Not really. Not unless you have a really big room. You can put together a full range, low distortion system for the average American den or living room for less than $7 grand. We can argue over soundstage, scale, brittle vs smooth and all the rest of the unqualifiable stuff that subjectivist audiophiles discuss and civilians are unaware of. And we can argue about tonality till the cows come home because even if we could get transducers and a room perfectly flat, neither one of us would like it and we'd enter the personal taste zone. But low distortion, full range, realistic volume in a moderately-sized room? 6 grand. 7 if the room is getting fussy and you need 2 subs.

I'm not sure what you consider a "moderately sized room". Assuming it's something like Bruce B.'s studio (about 23' x 13' x 10'), I think you'd have trouble doing it for $30k. 2 "good" subs alone would likely run at least $4k.
