I agree with with Larryi. As a speaker builder I respect his angle on design, implementation as in the right woofer for cabinet volume and other factors as in component selection. Cross over selection. Internal cabling, internal damping materials. There are advantages in smaller drivers, and larger ones. My first were 14" Alinco Aquadag woofer with 5" mid ,2" tweeter. The woofer had been in a larger room and was great . I would not want them in a small room. Now I live in a smaller space and the less efficient 8" towers I built are better suited for that room size. The bass actually goes lower on the 8" towers but in a large room would not have the same impact as compaired where they now sit. Placing a pair of Klipshorns in a small room would be a disaster. Matching components to the living space is very important.
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.
