I have owned 32 (still have some) of Tom's U.S.A. conical horn products over time.Lots of low distortion sound in small packages is his jam. He still plays bass along with his music. I hope Roy still plays drums an wears hearing protection. LOL.
I just designed and built a pair of d'Appolito reflex, twin 15" Eminence speakers with the latest concentric 2-way compression drivers in a PRV horn to replace the Klipsch Forte 1, just sold to my brother for his basement system. Leaving his Cornwalls upstairs for his wife's living room.
I'm bi-amping the passive woofer & mid-tweeter section with 2 PA-5's. An original one (over 2 years old, never shut off) on the high end and a PA-5 II on the bass, which of course uses 10-12 db more power than the horn portion. At 100 db/W sensitivity,, I never worry about enough power. I have finer control of relative amplitudes vs. Autoformers or resistors (it's "dial a fractional db control").
It's also called "great, useful watts" for the dolar.
Always look for what it Good in a product vs. the bad REVIEWS everyone else seems to seek incessantly, which prevents them from progressing in their quest for better sound.
