I went ahead and bought a pair of Audiopipe ATQ1000ND and disassembled them. They are definitely not clones of anything in the 2408h series - the phase plug, such as it is, isn't close to JBL's design. If you're looking for a 2408h-*, I'd go to Full Compass or Speaker Exchange and pick up one of the ~$50 ones with the JBL logo on it and a major distributor's backing.

Clones of the B&C DE250-8 available in polydamine and titanium. Anyone has experience with the b&c clones? I want to build an econowave active with these drivers, using the B-52 PHRN-1014 1" Horn 10" x 14" from Parts Express recommend by Patrick on another post.

^^^What is the CD you tested.


These clones are getting as cheap as chips. What are the two favorites?

I found on tmcelectronics.com another B&C 8PE21 clone. They do not mention of it has the copper core. It looks the same as the one from audio pipe.

Seller part number:MB-8PE2

I bought a couple of MB Acoustics 8PE21 clones a while back and found they sounded awful. Ripped the cone and spider off of one and didn't see any copper in it.

Regarding B&C DE250 clones, another relatively cheap route to that might be the B-52 COMP-4CLS compression driver. It's not just a clone of the Celestion CDX1-1745 that some people have called a drop in DE250 replacement, the Celestion and B-52 are actually the same thing - I bought 3 of the B-52s for $20 each and they came with stickers on the side that said "CDX1-1745"! Currently using them as tops with Parts Express's closeout B-52 clones of the QSC HPR152i waveguide and they sound great.

P-audio is a pretty big company that's been around a while and makes its own products in Thailand. Quite a lot of the horn flares are copy's of older JBL designs for a fraction of the price. I have been pleased with the the horns and compression drivers I have used from them.

Default Audiopipe redux

Patrick, it's looking like you were right that the Audiopipe ATQ1000ND may indeed be a JBL clone, just not of anything in the 2407 or 2408 line. I was researching other JBL compression drivers today and happened across the 2414h:



2414h

that is what I meant by the phase plug looking different. Seems to be a very different design - the ATQ/2414h is a mylar dome like that thread mentions. I'm also reposting some of audioheritage user pos's pics of the 2414h here, because they look exactly like the ATQ.
