The LFA's higher cone mass favored the bass end with less transient response at 700 Hz. The K-42, Delta Pro 12a, Kappa 12a, and the Celestion 1225 will all work with NUANCES of performance further overwhelmed by Room, and Placement within it. It's all Good Soup! It's also how much salt do you put in it for YOUR taste buds? Either way, it's a huge improvement over the original PWK version.
I have used both the K42 and Celestion TF1225 in Super Heresy builds and they both sound excellent. Best (real) bass you will hear out of a 1.65cuft enclosure.
I recently sold my Super Heresy I to a good home but had a few people reach out about modifying their Heresy II for the Super Heresy.
@claudej12000 do you have your recommended mods for the H2?
Dave Ault Large Mahl V2
Keep the crossover (just recap)
Add the 4 inch port
Egg crate on the inside
Which woofer is best? I’ve seen a lot of options

No. Not tested, I only work with v1's or 1.5's (not by my choice). You can't go wrong with THD+N's recommendation. I always showed curves and since I can't for this, you have a good shot on your own, though.
Hey curious if you made those adapter from 1in 3bolt to 1in 2 bolt how thick is it and what size bolts did you use because it looks like screws into your dukane 5a540 and did you listen to your dukane how do they compare and sound to others because I got a pair also
Hi
Sorry, I’ve really been in other things for a while.
The adapters were something I made to test mount the Altec 511 horns on the Dukanes just to see what would happen.
They are made from 1/2” thick Lexan/perspex. I believe the hardware is 1/4”-20 pitch.
In hindsight, the 511 were no where near “mint” condition…I probably should have just transferred the new bolt pattern and drilled the pattern into their flanges to avoid the additional 1/2” + gasket throat depth.
I don’t remember if I took any sweeps of the 511 with the Dukane at the time.
I do remember that I was testing the Dukanes and some Radian 760pb at the same time along with the 511, B52 buyouts and some wooden Edgar Tractrix horns.
Out of all the combinations the Dukane/B52 won in regards to smoothness and extension.
I think I came across some sweeps I took with REW…I’d have to dig for them.
