1x18 Horn

Not including heatsink fins, isnt this a similiar setup to labs?

Dont think the lab driver is touching alu pane, but it probably is much closer.

AB36 design include alu panel, so I'm presuming it would help somewhat?

I just got in touch with a marketer and hobbyist who did a bit of research on the CV cabs, he's very efficient.

'The Aluminium removable panel is purely marketing, they are all the same horn yet Cerwin-Vega charge more for ribbed aluminium in higher end models'

AFAIK, labs have tiny rear chambers and the alu panels are very close to the driver.
Still, with a big magnet woofer the panel may be close enough to make a difference, though I doubt it. Wayne Parham came up with a mod that made a little extension to touch the pole piece with alu pipe but many aren't convinced (heat in VC...). To the lab of course.

Simon, mykey uses your paras to do the WSX thing, I don't think he can post the Brute 45 paras for obvious reasons. The port being more efficient than the horn is amusing.

Well, playing music with "high sub content" will result in Voice coil/air in rear chamber getting hot and causing compression.

So I would prefer the possibility of some heat conduction out of the chamber, than none at all.

Maybe even more beneficial to alter the shape of the chamber such that the rear of the driver magnet is as close as possible to the alu panel.

I was thinking of making some protrusions on the inside of the chamber. In aluminum of course. Altering the rear chamber shape might be a bit much when regarding the other end of the horn flare's expansion. We don't see this (the alu plates) in many other 18" bass horns, so I'm not exactly convinced of whether it is worth the effort. But worth a try in any case, you never know.

If it didn't look like such a bloody chore to do so, I might be more inclined to pull of the heatsinks on my Stasys and see how Rog has done it.

chamber with a nice big port in it, driver won't get hot

Lev, i wish you would stop WISHING that by just putting different drivers in cabs you will hope for mirracles

Vega bins have had their day mate

it's simple, just get a piece of alloy machined to fit snug around the magnet thats attached to the heatsink

it's not rocket science

theres still no point if like the lab when you stack the cabs, all the panels are either on the floor and under upper bass bins, or flush against each other.. where does everyone think the heat will escape to? your more likely to hit xmax than thermal limit with modern glues.

That is a good point! never thought about that, why bother getting the alluminum panels for the labs!?!
