Yeah, I'm not using 2032H, and don't intend to.Originally Posted by johnaec
Here's what's going on: I wanted to try approaching this project from a different angle. Instead of pushing the HF response of a general-purpose mid driver, how about using a "real" tweeter like the new 2407H and pushing its low end to mate with the woofer? While a "similar" device (BMS 4540, 5/16" shorter "snoot" bottoms on some JBL horns,) has a manufacturer's recommended crossover frequency of 1.9 kHz, but can be used lower, apparently.
So, I look to what JBL is doing with 2407H, particularly in combination with my favorite PT waveguides, and find that JBL's using it at 1.3 kHz. I know from prior experience in this thread that's workable with extended-bass woofers like 2235H and LE14, but my first tries with it sounded bad, as confirmed by Toddalin coming by to listen. They're being pushed too low, perhaps.
Back to JBL's use of them as model. It's done with 24 dB/octave crossovers. I try that biamping with M552 active crossover. Much better, so I build the AM4212/00 crossover, with good result. That product uses 2023 as woofer, but I need 24 dB/octave on the LF as well, so I'm using AM4212's LF filter with LE14H-3 instead, is all, a mismatch. There are consequences, as outlined above. Not fatal, surely, and perhaps beneficial, even.
That's what we listened to last time you were here, using the inexpensive PT-F95 horns.
