id imagine with it being twice the power handling that would be the case

good point

Yep, the SoloX 18" uses a 3.5" voice coil. =]

what would something like this cost in a 12" version?

why do none of your coils have drilled holes between the coil and triple jointt? this can make a big difference in cooling..

Sick thread, if I knew you guys could recone my OZ Matrix Elite 10s, I would send them in ASAP. Even they are currently working. Lol.

Eh, not really. My experience with holes in the former has been more bad than good. Cooling isnt't helped all that much (unless the motor and frame are specifically designed to make use of them), and crush strength is definitely affected negatively.

I see no real benefit to them IMO.

My testing shows the same... unless the driver was designed around using the holes to direct air-flow in a certain fashion they will hinder cooling.

I've used them before to pick efficiency back up in solid core drivers -- NS v.1 was up 0.4 dB with a vented former -- BUT the thermal handling was decreased a bit in the process... as the design was already well in excess of the rated 1500 RMS we did use the vented formers on production, though.

Thanks guys!
Mitch - Did you build an MTX 9500 18"? We'd love to see it!

No, but I saw a MTX 9500 motor for sale and pondered the idea of building a custom 18" with it. Until this I hadnt seen a custom sub built from the MTX motor. Great work!

same with that RE XXX.. fusion looks interesting.

also the DIYMA r12 has a sweet looking motor there.
