The issue is sheer cubic volume, which affects bass response, to overcome this you need multiple high output subwoofers and a way of rolling off the bass reponse that the smaller mid woofers or lower woofers in the main loudspeakers would see therefore, those drivers would not have to go as low which would increase power handling and provide enough sound pressure levels to provide clean undistorted sound to fill up the room. This can only be accomplished by an electronic crossover either in the preamp or a control processor.
Same things with panels they can only move a tiny fraction of space before they compress and hit the limits of their physical stops, which is why any flat panel loudspeaker needs to be gigantic to play loud and they still won’t play that loud, ever go to a concert and see a planer?
The way to accomplish this goal
1: Multiple subs 2 with an electronic crossover which can get expensive and most electronic crosovers suck then you have the cost and physical look of two large boxes in addition to the mains.
2: A horn loudspeaker which again tends to be big and ugly and many times very colored without the delicatness of a great conventional speaaker, but great for rock and EDM ala a Klilpsh Lascala
3: A high efficiency large conventional loudspeaker with an electornic crossover and dsp.
4: A Golden Ear Triton Reference is nearly the perfect answer but we think this gentleman wants to move into an even higher end loudspeaker.
4: Pro audio loudspeakers or PA or DJ rigs.
If room volume and desire to play loud weren’t an issue than almost any good high end loudspeaker would be fine.
So there are a number of issues to make this gentleman happy which is why we recommended the Legacy Focus and Wavelet combo.
The Wavelet’s Bohmer room correction system provides a phase coherent sound in the room at the listeners seat.
The Legacy’s high power handling and high efficiency means that there will be many nights of fun parying without melted drivers.
We are also not saying that our products are the only game in town see comments as stated above.
We also build professional theaters the concepts of high dynamic range, high output and room filling bass all apply.
