I currently own 2 gnx124's, I came across some 2- JL 12w3 v1's. The weak link in my system is my sub amp it's a Jenson that claims to put out 200w RMS x 2 bridged into a 4ohm load. I know this is a Polk forum but I was looking for some honest opinions. Would the 12w3's hit harder with my current amp??? The sensitivity on the gnx124's 93db, the 12w3's 87.2 db I think. What do you think?
