I am currently running a Cerwin Vega CLS-15s subwoofer. I really have no complaints with the subwoofer aside from the gawdy surround and dustcap. I recently switched my main speakers to a pair of JBL LSR305 studio monitors and the sound is amazing. I found JBL GTO1514 car audio subwoofer being used in other home theater applications and on the surface it appears that it would be a nice drop in replacement. Here is the tech specs from JBL:

And the manual on the CLS-15s:

I believe the enclosure is 5/8 mdf and there is one vertical internal brace towards the rear to seperate the 300w bash amp, and two ports that I believe are 3"x12".

What's your opinion on this swap? Am I wasting time and money?

Without the TS parameters of the cerwin vega sub, it's going to be difficult to do a proper comparison.
The jbl sub on paper looks like it would be best suited to a sealed enclosure. An optimum sized ported box for HT use is going to be quite large.

That's what I'm seeing on my winisd box software. I'm going to take some measurements tonight with the rew and see what my actual is now.

I've just plugged the jbl specs into winisd. Sealed 150L will hit Xmax with 250w and give 101db @ 20hz. Ported 320L will hit Xmax with 300w and give 112db @ 20hz with roll off at 18hz. So the ported box would be way better but at over 11 cu ft, it's massive.
