Input:
I bought this product after reading the stellar reviews here and the professional sites. This is replacing a Bose Companion 3 Series II that I purchased about 3 years ago and went bust, and which cost me about x3 of what this system costs.
Words can't describe how superior this is to my previous Bose system, you hear every breath, every string on the guitar, every puff on the brass and every nuanced sound that was often missed in the Bose. Don't get me wrong, the Bose is a terrific system and was completely adequate at the time, but until I hooked these up I had no idea how incredible computer speakers can sound.
Warning: the sound is at FEROCIOUS levels! I have mine at about a 2-3 (subwoofer at half way) and it completely envelopes the room with rich deep sounds, and at half it has the windows rattling and the neighbors pounding on my wall.
Another plus is that the wires are at a very generous length and easily spanned both ends of my large desk.
