Who knows. Here’s the 15” woofer my new build gets.

It does seem to have the same surround as the JBLs.
Open baffle speakers
Open baffle speakers design is the simplest , to get bass response similar to other design , like ported, the baffle size must be huge to avoid low frequency degradations . Tipical size the baffle width 10-20" got weak bass performance. I am wondering how open baffle speakers design became so popular ?

No not quite, though it appears to be a "double roll" rather than a simple foam. It would appear that your selected surround is "applied" to the cone whereas the JBLs are a "part" of the cone and of different material. Of course the JBLs also have bigger voice coils, more tesla, higher BL, etc., but I don't think they are suited to open baffle mounts. Another qualifier when I put these together was that there would be no foams to rot and replace, again at the expense of deeper bass. |
@toddalin That’s very interesting because a lot of classic jazz guitar amplifiers also use Alnico speakers. They’re some of the finest tones to be had from a jazz guitar amp, of course powered by tube amplification. |
I have friends with Lii speakers. They think they sound great... meanwhile all I hear is "HONK". The primary factor for them cutting a piece of plywood and mounting a big Chinesium driver was... as usual: |
