Finally got this kit installed and had some time to play around with them.

Initial thoughts:
The light effects are a nice addition to games. The lights consist of three parts, a wall washer unit (with three separate flood lamps), and a pair of speaker top lamps. The wall washer unit is ideally placed directly behind your monitor facing a wall. If the wall is too far (more than 3ft.) the effect is lost. If your room is not dim enough, the effect is washed out. (Ideal lighting level is anything dark enough to keep you from being able to read effectively.) The lights on the speaker tops are made to be placed at the edge of your peripheral range to the left and right of your monitor on the top of your desk. If you place them too close to the edge of the monitor the brightness can be a bit distracting.

My Kit came with the Fans and Rumble wrist pad. For games like Farcry2 the fans and rumble pad was a cool effect, but it was rather gimmicky. The game has to have native support for this two optional add-ons. It take a lot of tweaking and fine tuning to ensure that the speed of the fans and the intensity of the rumble pad "fit" into the game play. Game like WoW do not have support for these functions. I am looking forward to seeing these two pieces usage in other games to see if it gets better.

The speaker set is a 2.1 arrangement. The sub is powered and has its own volume control. I found the sound quality from this set to be rather poor. The Sub does not produce very low bass sounds, and tends to rumble and rattle at higher volume levels. The front speakers did offer a nice range, but tended to be poorly matched to the mids and the lows coming from the sub. These speakers may be on par with average 2.1 powered speakers in the $40-$60 range. I do not recommend the 2.1 system.

My multibox setup totally did not work out with this kit. I am using a 2x3 - six monitor configuration. The cables were way too short to be able to reach the extra distance I needed and because of the height of monitor arrangement, the wall washer effects were obscured by the upper monitor. My existing speaker set was far superior in sound quality to the amBX set. I did find an acceptable solution rather than return the set. I mounted the wall washer to the backside of the upper center monitor and attached the speaker pair with the lamps onto the Monitor mount poles holding the left and right monitor pair. This raised the lamps up high enough that the effects are visible. I also added the speakers in as a set of Rear Quadrophics speakers keeping my existing speakers as the fronts.

If you play in a dimly lit room, have a single primary monitor, and often rely on headphones vs. speakers for your game sounds, and often play from the list of currently supported games the amBX might be workable for you. :thumbup: Otherwise, I'd recommend on passing on this gear. :thumbdown:
Make sure you shop around, prices on this gear varies greatly. The Set I purchased was the Premium Game kit, which listed for $279, and I think I got it for $149 at tiger direct.
