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 :)

GunSlingerGirl Anime Brief Review...

This week I finish watching GunSlingerGirl. At first sight, this anime is really boring. The opening and ending musics don't suit my appetite, the story is a liitle bit slow, etc. But the graphics is really good. Not awesome, but good indeed :).

The story is about 6 girls who have been granted artificial body because of several reasons. One is being told having bad parents who tried to kill her in order to have the insurance money. One is being told have a very weak body, etc. Shortly these girls have a super power because of the new body and they will have to endure dangerous mission.

If their body is hurt by weapon (bullet, knife, etc) then these girls have to go to special hospital in order to reconditioning their body. The side effect of this reconditioning is they will lose some memory and their live will be shortenen. Sad story, isn't it...

In doing their mission, each girls will be accompanied by an older "brother" and each couple then will be called "fratello". The background of the story is set in Italy, so no wonder there are many Italian style we'll see when watching this movie. As we know that Italy is famous for their mafia-like lifestyle. And this style will be adopted by the producer of GunSlingerGirl anime in telling the story (So please expect many gunfiring actions in this movie)

Overall this anime is average. For me who likes more actions, the storytelling style is quite boring anyway. But it is still quite acceptable. Well, is it worth to watch? Hmm, I can only suggest that if you have a lot of spare time then losing several hours for watching this anime is quite okay. It's not really entertain, as the climax is not too distinct. Sometimes in an episode, the story just flow flat without put empahize on some factors. But in the near-ending episode, the story is getting better and better, but can never touch the word of excellency ;)....
