Ofcourse Bose has an anechoic chamber. How else would you expect them to seriously test and measure their designs? I never said they don't have one. That being said, whatever their design philosophy, I just don't think it results in good sound. Their stuff may sound amazing to most "consumers", who will buy it, which in turn will pay the share holder's bills. All just fine. But that still doesn't change the fact that their gear costs too much compared to what you really get. Which is basically an inherently poor performing system, with small, light, underpowered, plastic speakers, with huge distortion figures and a DSP that processes the hell out of the signal in an attempt to compensate for these shortcomings. And, granted, viewed in the context of the package, it works quite well. The system as a whole sounds, as I said, okay and mostly just BIG. I just prefer a more natural sounding and more dymanic presentation than what Bose has to offer. If someone else prefers Bose, fine.
Don't ask me for measurements, because I don't have them. I trust my ears to tell me what's wrong with the presentation. But I do know for a fact that Bose up until not too long ago used production techniques found only in really cheap, chinese audio brands. How? By taking a blow up system apart. Today thay seem to have transtitioned to better quality components, which is audible. But... it doesn't change my opinion.
And speaking of Logitech: I'll take this Logitech set over anything Bose has to offer - any time.
Sorry. I just. Don't. Like. Bose.
