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


With the right electronics good 8" can go down very low and relatively clean. And if that's not enough, well, two 10" subs would do it. 
Opinions?

X2 on show me the music .
What constitutes affordable? I will say it till im blue in the face there are numerous spkrs with smaller drivers that are beyond killer . I have had probly 40 pairs of spkr in my yrs . Again my cerwin vegas in the 80 would peel your face off audiophlie nada . Kef,infinity,polk,logans,ads,ar, maggies,proac etc. etc rel velodyne hrs sunfire 8-15" subs etc . Jazz progressive rock and Rock mostly,guitarist arist for 30 yrs . I have adagios in my audio room 2 6.5" underhung transmission line floor standers love them . Sunfire hrs12" 1000w sealed spiked sub . Rarely turn it on treated room . Earth shattering bass no, bass hell yes. Room treatment and eguipment play a huge roll . 500-700 bks does not make a world class sub lets get what the goal and budget are first . A serious 12" driver alone is 500bks if you want to rattle the walls go big if you want accurate ya better be ready to drop big bks if your talking audiophile quality. Jl is the mark imo for the bks around 2k for a 12" . I would rather have two 10" jl audios then dam near any single any size sub until you start talking serious bks 5k up each .classical music generally goes much deep then rock as most of you already know

If you listen to big orchestra and opera you are in trouble from all directions beginning with the recordings and the size of the room. Any system that can convincingly separate and reproduce 100 instruments? They don't even quite know how to record it. Understandable, that's very very tough. Suppose they managed to get it close, you will need half a million dollar or more system in a giant room to make it more or less believable. One can still enjoy it under more achievable circumstances provided the expectations are not high.
Maybe I don't anything over 8", but extremely happy with my 10" paper cone woofers, 5.5" Kevlar midrange and 1" aluminium dome tweeter of Aerial 10T speakers.
Obviously no need of any subwoofer. They go low-enough.
