RLA Emerald drivers?

[BradKatz]

I have six that need to be reloaded.
I've been using McCauley, but they need special gaskets and are prone to failure. They do sound nice while they work though.
Any recommendations on driver's?

Thanks for any help!

Hi.

The Emeralds are folded horns. You can use any driver designed for a folded horn pending on your budget.

Most horn loaded subs should have a shorter voice coil woofer. Which McCauley's are you using? What is failing? What is this special gasket?

RCF L18P200-N for the old school sound.
B&C 18TBX 100 for the impact.

Both of those drivers would destroy themselves in a folded horn.

Muhaha.

The RCF is the original driver EAW used in there last BH882.
Two of my Bertha's working over 6 years now in a club with these drivers on bridged (and hard driven) Crown MA3600.

And the B&C is the driver Martin Audio put in the Levans @MOS.
Another pair is playing over a year now with the B&C without a single problem.

Are you certain that EAW used that exact model number you suggested? As far as I remember they used a different model number, which is obsolete by RCF. The B&C 18 TBX 100 is only popular because Danley used it in his design and, many are assuming it is ideal for a folded horn despite Danley not using the B&C 18 TBX 100 in a folded horn.

If you view the TS Parameters of the Precision Devices PD 1850 & Eighteen Sound 18NLW9600 you will see why they are the most popular drivers on market for folded horns that offer a sealed back such as emeralds.

Both of those driver models listed have pretty long voice coils for a horn loaded sub that has a relatively high low frequency cut off.

While I'm not sure about the RCF, the B&C is a pretty robust woofer. The TBX series had a splitting ferrite issue for a while, I'm pretty sure they've fixed it.

EAW might have used the RCF driver because at the time they made the BH882, they were all part of the same company.

It's certainly not the optimum driver for it nor is the TBX100.

What about the JBL 2242h... these thump.

[charles0322]

BINGO! That is driver in the Berthas at Club Stereo.. and since they use TAD for the dual scoops on top I think they are using the best for the thump.. a bit pricey but these fail very rarely

the dd is not, it front loaded horn with phase plugs in my perspective
