How about the 8" coaxial version in a small sealed box and an 8" sub on either side of it that is powered with a SA-1 amp?
I’m guessing the sensitivity of this combination would land in the mid to low 90s. That probably is not a big enough difference from a Neo3 to justify all the work to create it. I think what I’m learning is that there is no free lunch. You can’t get 100+db sensitivity which would be great for home theater in a package that most people would want in their home.
In helping my non-audiophile friend plan his HT, I think 3 L/C/R Neo3S with a couple of Rhythmic prebuilt subs will blow him away.
