I have been using 2 of these for 2 channel audio and would like to install new drivers as to tighten things up a lot. has anybody just replaced the speakers in these sub woofers, and was there a improvement in sound ? if so what drivers did you use. kind regards

Have you tried running the subs in sealed config or using EQ 2, Q.3?

[kully560]

hi Kevin I am currently using eq.2 and Q3 and with 1 port open

I would try running sealed in that configuration and see if that tightens it up a bit for you. If you have it up against a wall, you could also try moving it a bit forward, but generally changing the port config, EQ, Q controls work quite well.

thanks Kevin I will try sealed and let you know kind regards

hi Kevin I prefer the eq2 and q.3 with both ports sealed as it seems to tighten things up a bit more for 2 channel audio. I know these are not the most expensive drivers for the price that these great subs cost . but would better drivers help out a lot more , or running a separate crossover with external amp be better?
