These speakers are the first 5.1 speaker system i have bought. before, i had a stereo, and i connected to my PC, with PowerDVD and with Trusurround( a 5.1 simulation service with a 2.0 system), there were no complain at all, although i wanted to give it a try with true 5.1 system.
I was checking on Internet for a 5.1 system not too expensive, in fact creative speakers are cheap,but the bad reviews made me change my mind. so i dicided to go on Logitech.
i was about to buy the Logitech Z-640 6 Speaker Surround Sound System, the price is low (40 bucks!), but i checked the logitech web site, and there were new speakers, this speaker were just 10 more bucks than z-640, and the review i saw on: digitalreviews.net
that practically says that this speakers were comparable with the Logitech's higher end models such as the Z-5300 that cost more than 150 bucks, so i bought it.
i have just tested yesterday, connecting with a dvd player, that has dolby digital decode built-in, maybe this kinds of dvd player has no good quality decoding, but the sound i heard yesterday was amazing, especially the subwoofer, it's like the theater sound really.
Although the power is only 70 watts, and with peak of 140, the sound power were outstanding.
I tested with, Return of the king, Das Boot, The impire strikes back, kill bill vol 2, and it's like to see a new complete different movie!.
Imagine how it's gonna sound with my Audigy zs 2(thx certified), that i have just ordered from Amazon.
Update()
Well i have just set up my audigy zs 2 in my pc, and i was blown away, you can clearly notice the direction of the sound, i was watching kill bill vol 1, and for the fisrt time i was listening new sounds, i have never listened with my stereo system before.
and the subwoofer is really unbelievable, you can turn the volume of every speaker off and up, and the subwoofer too.
but in high volumnes the bass loses....
there's also another problem with the sub, it mixes with the front speakers, so when there's voices in the front speakers, you can hear voices comming out from the sub. bad!
After reading the bad reviews for these speakers, i must tell you that these sepakers are what you paid for.for music and games, the sound would be not so good(because of the lack of mid range), but for movies, o my god for 50.00 bucks you never find something similar, every night i watch the lord of the rings (the pallenor fields) in DTS with the audigy zs 2 sound card decoding, you hear voices, sounds(behind you) you'll never listened in an stereo system. it's amazing what you get for only 53 bucks.
There's also a scene in Kill Bill Vol 1 when the bride wakes up after the coma, there's is a mosquito sound that makes you belive you have one behind you, i always show these for demostration of sorround sound to my firends, and i have a good time watching their reactions, amazing.
i gave five stars because of quality - cost. you will never find something similar under 100 bucks.....
if you don' like it, go to buy the Logitech Z-5500 ($300.00).
So what's 250 bucks HE!!!!
