Newbie here. I need help.
I have a JBL (yeah, I know, I know) speaker setup for 6.1. I listen to mostly tv/movies and some rock thru this system (all top of the line Panasonic electronics...yeah, again I know...).
JBL S312's
JBL J350 surrounds
JBL N26 back
JBL N-center
JBL S120PII sub (400W)
The problem is the sub. I get nothing but rumble, and lots of it, but no punch at all. No sharpness. Is this the nature of my setup, a faulty sub (it HAS been in the shop...it's remanufactured), or just the nature of JBL subs? I've moved it everywhere, but still no sharpness. Do I just want $2K performance out of a $400 sub? You'd think I'd get at least a 'bonk' now and then...but no. My neighbor's cheap 8" Onkyo is WAY sharper sounding.
Please help.
