what u mean by processin cap? and with "bent"

thanks

as told allready many times 18sw115 (same spider for ds) won't fit in normal size scoop, is too deep u need to have a deep front chamber... possible but not for plans like super scoop!

Hi, could someone please give me a suggestion on what would be the minimum gap/clearance size between magnet assembly of a Nd driver and front chamber's rear wall? Is the efficient cooling of coil the main concern or are there some other factors to be worried about?
Maybe someone has tested this already, which would save me some precious time. I'm looking for safe long-term operation.
Taking the SuperScooper plan and suggested PD1850 driver as a reference, there is 45 mm gap.
My question is, if 20 mm gap and Nd driver would do the job as well.
Thanks for you opinion!

Hmm, friend of mine now wants to trade my single 18sound 18LW2400 to two RCF LF18X400's..   has anyone any experience of these RCF drivers in scoops?  Maybe I should change that anyway. One good driver to two good drivers for free, not too bad? :)

pretty much correct indeed, oh well..  I'll go for it then :)

Would be nice to have some of those very early cerwinvega "cinema" horn subs from 70's :)


LOL, I've had 16 pcs of these and 16 pcs of the keeles W-horn.
Nice not to have that anymore :-)

Hey, I have opportunity for cheap 18sound LW2400 but it has 4ohm voicecoil.. is it worse than 8ohm version? As far as I know, 4ohm has lower BL than 8ohm?

So what do you think, if it is any good for scoop?
