You don't need to spend $10-15k to get a $10-15k speaker. All you need is Tekton Moabs. Of course, if it really is important to spend all that money there is always the Ulfberht. However, just so you know, when I was all set to buy Ulfs the one guy who has heard them both in his own system and who bought Ulfs (before Moabs came out) talked me out of them saying the Moab is so close to Ulf for half the money its just not worth it.
They have terrific bass, superb imaging, dynamics galore, and everything you throw at them sounds just beautiful because they have the best midrange, way better than you have any right to expect for such a reasonable price.
This is all possible because Eric has developed a technology so new and different hardly anyone understands it. But this is how he's able to build speakers with relatively inexpensive cabinets and drivers that far outperform anything similarly made. Others have to use expensive proprietary drivers and construction techniques precisely because they are working in the old outdated paradigm. Oh well.
Put them on springs, by the way, this will not only improve the sound but decrease structural transmission that is the real source of your noise concerns.
