They will be going into Karlson cabs - so ported with horn loading - 3-4 cubic feet. I have a crown psa-2 amp to drive a pair ( 275 w/channel @ 8)
thanks

Have no knowledge of karlson cabs - can offer 15" woofer suggestions that work in bass reflex cabs as subs.

JBL 2235 is great. Only available second hand though as its discontinued. Adire Tumult is also good quality stuff although you need over 2KW to hit 120db due to its very low efficiency. Don't use the Tempest. I think TC Sounds also make some nice 15"ers. Again, no idea weather or not these are suited to karlson which I assume is a horn.

However, it's too soon for me to praise or damn, grin or grumble, because I still have to build cabinets and mount and connect the horn and drivers.

Here's the comments the aforementioned John Ridley sent me:

Assumimg [you're using a] conventional direct radiator in a box, and not horn loading, the general consensus of learned and informed opinion among the pro guys in the industry, recording/tv/radio and at home is that regardless of brand considered, it simply doesn't get any better than a pair of JBL 2235. These are ceramic 15" LF drivers with a 20hz fs and ran in ALL the JBL studio monitors for 20+ years without them being able to dream up a single way to improve them further. That is saying a mouthful.

If you're interested in purchasing a pair, there are a few options:

1. There's a pair on e-Bay right now that needs new surrounds.
2. Jammin' Jersey Music and Pro Audio in Northridge, California (www.jamminjersey.com), where I purchased mine (not cheap: US$500 + shipping), still has a pair advertised on their website--or at least a few days ago, when I last looked. In any case, it's worth phoning them, as their stock is also changing.
3. There is a place in the eastern U.S. (New Jersey?) that quoted me prices for brand new sealed in the box 2235s. I don't know if this means NOS, but the gentleman specified that the drivers came with warranty. The following is from the note I received about this from Mr. Ron Gold (sales@goldsound.net):

The following JBL units are new, in sealed box with full 5 year
warranty: 2235H, $369 each; 2405H, $298 each; 2382A. $298 each.

Hope this helps!

There are other good options too; It's kinda like like choices for good cars and good engines. If it's cool and fast, then it's cool and fast. But I gotta say I love the pure clean power of the 22xx JBL's, and the ones that are tuned low make really great subs.

I'd definitely consider the JBL 2235 for 15" subwoofer or the JBL 2245 for 18" subwoofer.

They're really sweet!
