Your definition of concert level sound and the rest of the world may be a bit different.
As per Home Theater your definition of what constitutes a Home Theater again I am willing to bet is different then ours.
Take a look at what a real Home Theater looks like in the video and our flickr. What you are talking about is a Media Room.
A real Theater is both about quantity and quality, and we are trained professionals in Home Theater after taking courses with Toni Grimini, Keith Yates and Russ Herschelman.
An 85db loudspeaker will go into compression at realistic theater levels which can routinely hit 105+ db, unless that speaker can handle a lot of power which means big voice coils the only 85db efficient loudspeakers that we have suitable for Home Theater are the ATC which can play all day loing at 108db as they are deigned for professional applications.
Would you also like a quote from John Atkinson, not about a $62K speaker but a $20k one that also includes a preamp, a dac and a room correction processor: The Legacy Aeris:
The combination of the Aeris and Wavelet provide some of the most musically realistic sound I’ve ever encountered. They take digital processing and room correction a vital step forward, and show they can reach levels that are competitive with even the best purist speakers.
You would be amazed at what a $7,000 pair of Legacy Focus Signatures can do compared to many of the $14k loudspeakers out there.
If you are in our neck of the woods you should experience the Legacy line they are unbelievable loudspeakers and an incredible value.
