I would also suggest Pro Audio Gear. Designed to "Rock and Roll" large venues.
Suggest NOT Bridging. Back in my days most pro speakers were 4ohm. Amplifiers that are bridged do not like driving 4 ohms loads. I would guess there would be 8 ohm speakers available now. Buy 4 (2 pairs) of speakers. Drive each speaker with the two amplifiers in regular stereo mode.
Here's one thing your son can try right now to get his spl jollies. And not spend a cent. Move his Klipsch speakers into a bathroom or closet. Both speakers at one end and sit on the other end. Or each speaker on opposite walls and sit in the middle. Conveniently, might be the toilet. He may need it. CD player straight into the 7300, set the Gains to 11 and Rock'n Roll.
I do not condone listening of any music at high spl levels. Every rock concert I went to in the 70's, left my ears ringing. And notice it's effects now. Might be old age. But definitely didn't help.
