I've got 4 pairs of full range speakers with dual 7"s, 10", 12" and 15" woofers. Of these, the 15" Tannoys have the LEAST amount of bass. The ported 12's go the lowest, but the 10's are in a sealed cab, so they roll off more gently. The dual 7's are lightning quick, but don't have the 'gravitas' and punch of the larger woofers. BUT, since the OP has declared that 8" is the ideal size, I guess I will just dump all these great speakers and find some with 8-inchers.
6.5 vs 8 vs 10 woofer
IMHO I think the 8 is the ideal size cone for mid/small sized listening rooms. Even for large size listening rooms.
The lower mid hz's seem cleaner/clearer. And there is so little fq's in 905+ of the music we listen to, it seems to me the 8 driver is the most perfect size cone.
A 10 size cone has the potential to become overwheling, aggressive, attacking when amp gain is pushed just a tad too much, = Better volume control with a 8 vs a 10.
The 6.5 misses some of that lower bass which a 8 can voice superior.
After listening to several YT vids with a 10 FR, I had considered going 10, but i think staying with a 8 avoids regrets.
I listen at low/mid volume.
