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! |

Depends on processing capabilities of your system. As long as impedance and Fs of the driver is suited, and motor force with available cone excursion is high, it will do. Or rather it can be "bent" to provide you good performance. I'd recommend this driver for almost everything from 35Hz upwards.

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? :)

Remember, Bl alone cannot be measurement of raw force of the driver. You rather use (Bl*Bl)/Re to get the numbers right, and comparative. As long as your amp can feed the driver safely, there should be no significant difference or problems.

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? |
