Do we really need anything more than 8" woofer and 1" tweeter for medium size room?

Your question regarding the 8" woofer is perhaps more complicated the suggested. If you are talking about a two way speaker then it might be more advisable to find one that has a really involving midrange and nice smooth highs. If you have three drivers, a two and one half way or a three way you are more likely to find better tighter bass. Bass quality to me is far more important the the amount of bass, especially in a small room. 

Soundsrealaudio, yes I meant two way speakers, but we can expand the discussion, I think it could be interesting to many audiophiles and music lovers.
I agree of course about bass quality and its blending in with all other frequencies. The sound must be coherent not in pieces.

I have 7 inch 2 way towers that dig down plenty deep below 30 hz. However It’s in the volume that where they will never match a 10 inch woofer or multiple woofer system. Big woofer  doesn’t equal deep,  Big woofer equals loud + deep....but that’s just using my math.

We never did discuss Transmission Line enclosures either, or dual woofer scenarios.

Dual woofer's aren't quite as good as more diameter inches, but they don't hurt. :)

Eric i beg to differ ... I have adagios two 6.5 underhung transmission line . They share different frequency i have had probly 40 pairs if spkrs in 30+ yrs . There killer and go to 30 hz ribbon tweeters 2way
