My hearing like my eyes is awful. But I cannot understand speech coming out of the laptop speakers To save space I am musing the idea of one powered subwoofer and a pair of horn midrange speakers for the stereo thing plus a midrange like the Peavy for 39 bucks at Parts Express. I'd bet anything my hearing stops at 4K and above. Midrange from around 400 Hz on up would work just fine. Yep, one 6-1/2" subwoofer, one 5" Peavy midrange and a pair of upper-midrange horns.

Or like I linked to earlier, these Celestion full rangers 95->12K hz and the box tuning in sealed config is .11^3 ft. (cigar boxes). The celestions are 89db efficient which isn't the best but not too bad. That is one watt at one meter for 89db. A T-amp will drive them to ear splitting levels.
FWIW, I have 15" woofers that are 105db and midrange horns, tweeters that are 108db. You don't always need big power to get loud.
