I'm skeptical of any website using testimonials. Testimonials have no value whatsoever unless given by reputable sources, and in the vast majority of sites I've seen online offering them, there is always something gimmicky or shady going on.
I'm not saying that this is the case with this company, I'm just saying thats my gut instinct on it. I'd gladly give them a try to see what they have to offer, but not at my expense. I'd gladly hope on the bandwagon if after I've heard them in person and tested them and felt they were a good quality speaker.
Interestingly, I checked out their sub's specs.
Here and I think this pretty much says a lot. The quick blurb states the subs FR to be 35hz to 200hz, and when you go down to the page to the specification tab it states 65 Hz – 20 kHz. Its obviously a typo, but that leads to some obvious questions I think. A company that is legitimate, thats trying to prove itself, and is offering good quality products will want people to know that. They will provide as accurate as possible data, and make sure (especially when its an ID company) that the information on their webpage is as accurate as possible. Anything less is not professional, and does not bode well for them.
So like Johnd stated, they have to prove themselves first. So if you have an extra $200 lying around to try'em out, then by all means please do. And let us know your thoughts on them.
