I have 1 room: 2 channel music one end, small home theater across the other end of the room. the 2 chairs in the middle simply turn around as desired.
dbx soundfield 100’s are for the home theater.
I use their principle of cross dispersion with my music system sealed box speakers.
They are Custom Made, similar to Cornwalls, 15" woofers, horn mid; horn tweet, but the innards are all electrovoice drivers, crossovers, L-Pad controls.
here’s the innards
the parts all came from a 1958 Fisher President II Console I inherited from my Uncle Johnnie in 1973. That’s how I got hooked on great sound and tubes

The unit was up on 8" bronze legs, the woofers fired downwards, I made taller enclosures to face them forward, increase cubic feet, and a rear vent that is closed here, it was open in prior location with no wall behind.
