Except that things such as comb filtering will take place when you run more than one speaker from a single channel. In that case, more isn't always better.
In all reality if you’re wiring up two pairs of Heresys to two amplified channels you’ll be much better off selling them and getting a single pair of Cornwalls, forte, Chorus, etc.
This is Lady, a Cavalier King Charles. On the right is shortly after we got her. On the left is a pic from a few days ago. She’s about 5 months old now.
She loves to play, run and play tug of war.
Congrats on the awesome deal! I’ve had a couple pairs of RB-5s and they are really, really nice.
A sub pre-out will only send low frequencies so unfortunately that won’t work.
