Pimp my speakers

Well having blown the crossover in a pair of JBL JRX125 I have decided that enough is enough. By the time I finish with them the only thing JBL about them will be the cabinet itself.

both have already got, Paudio BM2-D450S comps

To this I am going to add 2x SOVEREIGN PRO 15-600N it will be my first dealing with neo drivers.

I simed them in win isd and have found that the ports on them are nowhere near big enough, (might explane the port noise at very low frequencies) so I am going to add two more at the bottom of the cabnet. This gives me a tuning frequency of 63.58Hz in a 140L cabnet, the graph looks nice and smooth and the vent mach is 0.10 so hopefully no port noise.

I am going to put a bit of MDF over the back pannel, and put 2 NR4s there and run the cabnet bi-amped with a crossover of 2.5k. under it will be two fane 18xb reflex cabs I will cross them at 120Hz.

Finally I have stripped the carpet off rubbed them down (the fit of the pannels on this cab is quite bad! you don't notice with the carpet on) and applied some turbo blue paint.

Going to run the comps on a C-audio GB202, the mids and bass on a C-audio pulses.

anyone got anything to add that may be helpful to me?

yep,  and the cabinet.

maybe you should of built some new cabs, and sold what you had

yeah, opening out a driver cutout by a few mm is no fun. i haven't yet worked out a good way of doing it with a power tool that i have.... i have succeeded a few times with a lot of effort and a surform though..

running a shallow semi circular file around the hole consistantly seems to work, enlarged my behingers to PD186 easily enough - just filled old holes, filed about 1.5mm out and added new holes+tee's.

Took all of 15-20mins!
