Comet series from Divoom, affordable home theater speaker system

Divoom always continue to provide us cheap and affordable speaker with sufficient quality. For the home theather segment, Divoom has their comet series product line. Comet series are really cheap for home theather speaker class. For example the Comet-D2 is bundled with price tag at approximately Rp 1.350.000,- while Comet-A1 is bundled with price tag at approximately Rp 2.300.000,-.

How about the specs? Each Comet-D2 and Comet-A1 come with similar specification. The most obvious thing is the subwoofer design. They are really look alike! And both speaker are featuring 100 Watt RMS output. However Comet-A1 do come with hardware decoder for Dolby/THX which makes its price higher than Comet-D2 ;). And Comet-A1 is bundled with speaker stand as well which will make the satellite allocation is easier than Comet-D2.


The specification for Comet-D2 and A1 series is as follows :
  • Total RMS Power : 100 Watts
  • Subwoofer : 50 Watts RMS
  • Satellites : 50 Watts RMS
  • Total Peak Power : 200 Watts @<10%>
  • System THD : Better than 0.05% THD before clipping
  • Signal to noise ratio : >95 dB
  • Frequency Response : 20Hz - 20 KHz
  • Driver size : 3"x2 + 1" (tweeter) high excursion satellites, 8" high excursion subwoofer
For small home theather system, these speakers may be the right choice for anyone in tight budget. If you have a lot of $$$ to spend for home theather system, you had better go with famous brand like JBL, etc. But considering its price, Divoom always offers us the best from their pocket :).

Monster sound from edifier!

Edifier, a chinese speaker manufacture, recently release a super montrous heavy metal speaker for music lover. It's S550 and S730 that will captivate heart of enthusiast people around the globe. Let's take a look at both of them ;)

S550, as we can see from the image on the left, is a really nice-looking design speaker. The speaker is designed and inspired by Phil Jones, one of the most famous audio artist who settles in Japan currently (if I'm not mistaken). Except the design, Phil Jones has fine-tune the overall sound of this speaker too, to be sound as please as possible for everyone.

But how about the specification. Below is the specification for S550 taken from Edifier website :

Specifications:
  • Power output: RMS 5 x 35W + 120W (THD=10%)
  • Signal to noise ratio (amplifier): >=85dBA
  • Input sensitivity: 5.1Ch: L/R: 480mV +/- 50mV SW: 175mV +/- 30mV
  • Stereo: L/R: 520mV +/- 50mV SW: 200mV +/- 30mV
  • Frequency response: L/R: 140Hz ~ 20kHz SW: 20Hz ~ 133Hz
Features:
  • Luxurious 5.1 speaker system with 10 inch subwoofer- Wooden MDF housing for all speakers
  • Passive radiator on both sides on the subwoofer to exaggerate bass performance
  • Magnetically shielded drivers for all speakers
  • Switchable dual input ports for both 5.1 channel and stereo inputs
  • Multifunctional wired controller with 2.5 inch LCD display (dimmer included)
  • Headphone output on wired remote controller
  • Master volume controls both speaker output and headphone output
  • Volume booster for extra power output
  • Separate bass and treble adjustments
  • Multifunctional wireless remote controller included
  • Dolby decoder circuitry included in digital version
Edifier S550 will be sold around Rp 3.800.000,-. Will the price worth it? For bass lover who need 5.1 speaker for their small home theater system, this S550 really can rock your room. Equipped with 10" subwoofer with 2-way design for each sattelite and 3-way design for its center channel will make S550 not disappointed.

Meanwhile S550 will be targeted to hit small home theater market, S730 is another beast from edifier targeted for music lover. This 2.1 speaker with its total 300 RMS has the power needed for shaking your small room!

The design looks similar with S550. This is really obvious because this one was also designed by Phil Jones! Phil Jones interference in the design and fine-tuning process will ensure S730 will have a maximum overall sound for music lover. Especially bass lover since it's using 10" subwoofer for 2.1 configuration. Only logitech with its Z5500 has doing the same thing. (Well, audiophile will say it's really overkill to have 10" in 2.1 setup, but who care anyway :P)

Okay, let's take a look at the specification, shall we?


Specification :
  • Total Power Output: RMS 75W x 2 + 150W
  • Frequency Response: 20Hz~20KHz
Features:
  • Heavy metal 2.1 speaker system with 10 inch subwoofer
  • Wooden MDF housing for all speakers
  • Multifunctional wired controller with 2.5 inch LCD display (dimmer included)
This speaker will arrive in Indonesia market around June. That's the information I got from official Edifier distributor in Indonesia. The price will be tagged at around Rp 3.300.000,-. Can't wait to audition this one. It should sound awesome!

With both speaker, it's clearly seen that Edifier has put so much effort for entering new level of computer multimedia speaker market. I think now they can be put at the same level as Klipsch, Altec Lansing or JBL in this criteria ;).

If only Edifier put the lower price tag for this speaker, I would be at the front row of sales queue, then :P. Absolutely!

Logitech speaker update...

After a while, Logitech updated their speaker product line. And this time, Logitech designs their can very neatly. This is a vast improvement from Logitech's previous product line. But is it only design or the sound quality is improved as well? Let's find out real soon!

Logitech has been a major player in computer speaker for the recent years. Their speaker characteristics are best suited for gaming and video purpose since their bass capability is able to shake room! And it seems that Logitech keeps their speaker characteristics to be just like that in the current product release. Enough said, let's take a look at two speakers worth buying from Logitech :)

The first one is Logitech Z4. Priced below $100, this speaker product will hit the market for gamers and movie lovers on budget. Why? Because there are no competitor so far that seems to offer 8" subwoofer on their speaker products for this price range. This is the main strength for Logitech Z4 - Bass. You may wonder, why size does matter for subwoofer? Because the larger the subwoofer, the lower frequency it can produce...

Logitech bundled their 8" subwoofer with 2" dome driver in Z4's satellites. Somewhat, we feel that this is unbalanced system. How can 2" satellite driver keep up with 8" subwoofer? The mid and high will be easily overwhelmed by bass the subwoofer produce.

To tackle this problem, Logitech invent a new technology which they call it pressure driver. Pressure driver is a passive driver whose membrane will be moved along with the real active driver. If we see from the image below, we can see that in each satellite, Logitech included 2 pressure drivers. And to reduce the massiveness of bass produced by Z4's subwoofer, Logitech apparently uses 8" pressure driver in their subwoofer with unknown size of active driver....







Something that is missing from this product is tweeter. If only Logitech include tweeter on their satellite, maybe this speaker will have more musical characteristics, but anyway this is a really good multimedia speaker for gamers and movie lovers. Just take a look for its specification and you'll realise that for its price - below $100 - this is a really good offer.


Z4's Specifications :

  • Total RMS power: 40 watts RMS - Satellites: 17 watts RMS (8.5 watts x 2), Subwoofer: 23 watts RMS
  • Total peak power: 80 watts
  • Frequency response: 35 Hz–20 kHz
  • Drivers: Satellites: 2-inch dome driver, 2-inch pressure driver, Subwoofer: 8-inch pressure driver
  • Speaker dimensions (H x W x D, inches): Satellites: 9 x 3 x 3.75, Subwoofer: 9 x 9 x 9.37
  • Signal-to-noise ratio: >92 dB



Another product worth buying is Logitech Z2300. This is Z5500's sibling, another great product from Logitech which is highly recommended. Catch a glimpe at the image below and we can see that the design of Z5500 is superior than Z4's. But how about the specification? Is it really superior? Let's see it!


Hardware

  • Drivers: Satellites: 2.5-inch polished aluminum phase plug driver
  • Subwoofer: 8-inch long-throw ported driver with sixth-order bass reflex enclosure
  • Speaker dimensions (H x W x D, inches): Satellites: 6.75 x 3.5 x 6, Subwoofer: 11 x 11 x 15
  • SoundTouch™ wired remote control: Master volume, Subwoofer volume, Headphone jack, Power/standby


Technical Specifications

  • Total RMS power: 200 watts RMS Satellites: 80 watts RMS (40 watts x 2) Subwoofer: 120 watts RMS
  • Total peak power: 400 watts
  • Frequency response: 35 Hz–20 kHz
  • Signal-to-noise ratio @ 1 kHz: >100 dB
  • Amplifier: Ultra-linear, high-capacity analog
  • Compatibility:PC or Mac, CD playerDigital, (MP3) music player, DVD player, PlayStation®, PlayStation®2, PLAYSTATION®3 (with provided game console adapter), Xbox®, Xbox 360™ (with provided game console adapter)



Z2300 has 200 watt RMS power! It's more than enough to make your computer table be shaken when you turn up this beast to its maximum. Z4's with modest 40 watt RMS really looks pale compared with Z2300. Being high in RMS power means that this speaker can be played at loud volume without have any perceived distortions. Logitech Z2300 also has been THX's certified which marks this speaker capability as small home theater speaker.

This speaker is offered in price range $160, making this speaker will face Edifier's C3 directly. Who will be the winner? You'll decide :)

Current top line of Altec Lansing Computer Speaker...

Just like Klipsch, Altec Lansing had being been famous in the home theater speaker systems first before they entered the computer speaker market. Later on, Altec Lansing is ultimately known as well-known computer speaker vendor because of their build quality and sound quality. Altec Lansing is close to Klipsch in terms of sound quality, but slightly cheaper at that time. So in this case, design is the determine factor for most people for choosing one. Besides for people who are willing to spend more than $250 for computer speaker, the difference of $10-$20 would not be a major factor anyway ;).


FX-6021 is the latest and the current top line of speaker Altec has right now. It features an unique design by introducing 12 microdrivers, 6 on each satellite. While the subwoofer design is minimal, it complement the satellite perfectly. Altec also include a wired remote controller for this speaker system. Just take a glance at this speaker and we easily become interested for its design. But how about the sound quality? Just take a look at the specification below first ;)

SYSTEM SPECIFICATIONS :
Altec Lansing’s superior sound comes from our proprietary technology, which utilizes custom-built, high-fidelity drivers, state-of-the-art equalization circuitry, and a harmonious mix of the following specifications:
  • Sound pressure level (SPL): 105 dB
  • Total continuous power: 75 Watts RMS
  • Front Speakers: 12.5 Watts/channel @ 4 ohms @ 10% THD @ 180 - 15000 Hz 2 Channels Loaded
  • Subwoofer: 50 Watts @ 4 ohms @ 10% THD @40 – 180 Hz Single Channel Loaded
  • System response: 32 Hz – 18 kHz (-10dB)
  • Signal to Noise Ration @ 1 Khz input: > 75 dB
  • Drivers (per satellite) : Six 1" fullrange Micro Drivers
  • Subwoofer driver:One 6.5" long-throw woofer
The subwoofer can only go as low as 40 Hz which is not too bad anyway as this is only 6.5" subwoofer. The configuration of 6 microdrivers will make FX6021 emphasizes high frequency and slightly lower mid frequency. Even the sound pressure level is stated at 105 db, I don't think there is anyone who wants to play it that loud. Our neighbor must yell at us before we can reach that volume....

In my opinion, this is a good speaker system. Excellent design with absolutely famous Altec Lansing sound quality in mind will certainly makes this speaker find its way into its lover ;).

If you're in tight budget and want to have a decent computer speaker, then I suggest you to take a look at Edifier R401 and M3300. Both are priced below $50, a modest price. But this is the cheapest price I know for speaker systems featuring 6.5" subwoofer. Even better, R401 and M3300 are equipped with tweeter on its satellite make this is a very good speaker for listening to music.

Let's see in details about what these speakers offer:

It seems that Edifier now discontinues its R401 model, so if you find this one in store nearby, go get it while stock lasts. And M3300, many says this model is a steal for its price range. M3300 is being said to have the best clarity and treble sound quality for speaker at its price range...

Edifier Speaker Update...

Just realise today that Edifier has discontinued some of its products, include S5.1 speaker. It's so pity because I think this model is a very good speaker system in its price range. But Edifier has added a new speaker series, they call it C series, into his line. Let's see what improvement Edifier made for the new series ;)..

The C series, unlike previous Edifier series, featuring separate amps for more better design. We do know that separate amps usually is present in home theater speaker system. It's a good idea for implementing this idea in multimedia speaker systems. In theory, separate amps will bring less heat to the subwoofer (as amps usually integrated there) and this will preserve the life of amps component. The front line up C series is C3 speaker. Just take a look at this beauty below!


Here is the details of Edifier C3 speaker

Specifications:

* Total Power Output: RMS 8W x 2 + 30W
* 8" Woofer Driver Unit
* 3.5" Mid-range Driver Unit
* 13mm, silk diaphragm
* 16.6Kg for single gift box

Features:

* 2.1 channel multimedia speaker with external amplifier
* Stand-alone 48 Watt external 'component' amplifier
* Complete wooden housing for all speakers
* Electronic Intelligence Distortion Control (E.I.D.C) inside
* Built-in MCU control with multifunctional digital display
* 8 inch driver for subwoofer with 2-way designed satellites
* Magnetically shielded drivers for all speaker

And Edifier also added S530D into its S series line. S530D is intended mostly for audiophile and music lover as its design is simple but elegant. It's equipped with a very nice-looking wired remote control and small wireless remote control. In fact, it is being said that the development of S530D series took almost 2 years. Enough said, just take a quick look for its appearance and you'll fall in love with it :P

Very nice and sturdy look as all speaker are made of wood! But how about the specification?
Below you'll find what you're looking for...

Specifications:

* Power output : RMS 35W x 2 + 70W (THD=10%)
* Signal to noise ratio : >85 dba
* Input sensitivity : PC: L/R: 600mV +/- 30mV
* SW: 200mV +/- 30mV
* CD: L/R: 720mV +/- 30mV
* SW: 330mV +/- 30mV
* Frequency response : L/R: 158Hz ~ 20kHz SW: 20Hz ~ 130Hz

Features:

High-End Computer Speaker for HTPC..

Nowadays, computer is more than office tool. Because of advanced technology, computer can now be used as home theater replacement or also known as HTPC (Home Theater PC). In order to build a HTPC, you'll need to fulfill several requirements by choosing the right components as follow :
  • VGA Card that has hardware acceleration for decoding video compression (H-264, MPEG-2, etc)
  • Processor with decent speed

  • High-Quality soundcard which support multi-channel (5.1, 6.1, etc) playback

  • A high-quality multi-channel speaker set

  • A huge monitor or LCD TV for displaying the movie

This article will focus only on speaker. Why do I only discuss speaker? Because I believe speaker is the heart of HTPC. You cannot enjoy any movie if you cannot be immersed by the movie's sound effects. And the main device for giving you the right sound as wanted by movie producer is speaker because the quality of sound-card onboard nowadays has been very good. So in this article, I will try to show you 2 high-end computer speaker products with best price/performance that can be used in HTPC.

First candidate is Logitech Z5500. Let's see the speaker first from the image below :

I would not describe in details about Z5500 technical specifications because it would be too long and besides, there are a lot of reviews there you can easily find about :). I will just tell you what make me think this speaker does deserve to be in your living room.

Ok, first is 10" subwoofer. Well, it is the biggest subwoofer in this class and price range. So when you choose this one, you'll be sure of have an enough bass to shake your neighbors' wall :P. Just kidding. Logitech speaker is famous of its huge bass. Well, sometimes the bass is boomy but this can be tricked by placing them in the right spot and help from equalizer :). But with the big size of subwoofer, you'll be sure to know exactly what the explosion should sound in the war-action movie.

Second, Z5500 is equipped with hardware decoder in it. It's capable of decoding Dolby Digital, DTS, and Dolby Prologic II signal. It also have 6 channel direct, StereoX2 and Stereo mode if you don't want to utilize the hardware decoder capability. This will add more benefit when you have, for example, a stereo sound card but you want to hear 5.1 Dolby Digital sound from your movie. Well, you can merely use passthrough mode of your sound card so the signal will be delivered as is to the speaker and then let the hardware decoder in speaker do its job.

Third, Z5500 offers wide range of compatibility mode. You can use this speaker for PC/Mac, CD, MP3, DVD, Playstation, Xbox and other gaming console. It's very nice to have such a versatile speaker that can be used for many devices you want to plug in. You will save room and money because you won't need to buy another speaker for every devices you have.

Overall, because of its configuration, Logitech Z5500 is most suitable for movie (THX certified) and gaming. It can also be used for listening to music, but for some genre music which need a pure-flat frequency response before it can sound enjoyable, you'll have to tweak the equalizer enormous times before you can find the right configuration...

Now the second candidate, Edifier S5.1. As usual, let's see the image of this speaker first ;)

Wow, now we see how the speaker should really look :). Edifier S5.1 is really elegant by having wood finishing instead of plastic/alumunium material usually used in computer speaker. The configuration is almost the same like logitech, i.e : 5.1 and have remote control. The main difference between this speaker and logitech's one is edifier S5.1 does not come with any hardware decoder in it. The other difference is the subwoofer in Edifier S5.1 is smaller than logitech Z5500 has (8" vs 10"). But it won't hinder this speaker to be in your living room as it has several remarkable characteristics as follow :

First, looks! In my opinion, this speaker shows us how the speaker should look. Simple and elegant. The choosing of wood as finishing material is brilliant as wood is also known as an excellent material for reproducing sound. It also have LCD display, but in this case the control center from logitech is far better :).

Second, tweeter! The satellite of edifier S5.1 are equipped with 3/4 inch cloth dome tweeter. This will ensure that you'll be able to hear high frequency sound like you often hear in classics music.

Third, price! What can I say? For a price below $300, you won't ask for more as this speaker currently is the best price/performance speaker set. But keep in mind that this speaker is most suitable for music. If you want to hear *boom* as *BOOM* then you'll have to tweak equalizer a little bit. Just make sure your sound card support equalizer or at least treble/bass configuration.

Overall, Edifier S5.1 is an excellent choice for anyone who wants to have a nice-looking speaker and listen a lot for music in their living room. The setup features smaller subwoofer than logitech, means that edifier's subwoofer won't be stand out as above its satellites. It will be balance instead.

If I have hot money to spend and should choose between these two beast, then I'll choose Edifier S5.1 as I like music more than watching movie ;)...
