Notice the driver has a 750hz impedance hump, but the combo horn/driver has humps at 1khz and another near 3.8khz. Notice no rippling in the freq graph (bottom right page 2). Look closely on the 2426h pdf plane wave. You can see the rippling between 1 and 5khz on page 3, and that is even with your 2426h driver.
Even then, it is a better sounding horn than most, but there are better. The problem with it (2344) are the slot (parallel), then the drastic break. I saw a post where someone love his stereo-lab until he stood up. I've been lusting for a jbl 2384 or a larger than stereo lab 400hz (um, 1' across horn won't hold directivity down that low), but I don't want the narrowing in dispersion that the stereo lab tractrix does (3 octaves wide). If they look like that Bi-Radial but-cheek, I would." Hell I think I'll just throw all mine away. But maybe some open cell foam would work. You probably don't have room to play with that in a 2344 though. Try the mouth edges, try near or even in the throat. You may/will have to add eq, but you start cleaning up the sound. If I remember, a newer jbl horn(one of the progressive waveguide) had a cleaner waterfall than the 2344 horn. That "live" sound is echo/reverb added (pleasantly hopefully). When you fix all these things, you pick up detail, like electrostat detail, instead of the "live" sound you get used to hearing. And to me you want a bit of curve, not a flat conical. You don't want "breaks" where the path (instead it bends and does so slowly). You don't want parallel walls (standing waves). Think of the sound leaving the hole in the throat (at the compression driver). But exposure is probably the best, so we can go and seek out, try, and learn. We are here to discuss, share, disagree, and maybe even learn a thing or 2. Opinions are like a holes, everyone has one. Nope, I'm not offended nor feel attacked. I recall reading that their sound was rather unpleasant as well. JBL 2370A Bi-Radial Horn seems a bit pricey $250.00.
It sounds nice enough, especially given the price of $15.00 each, but response falls off the cliff under ~2khz or so and the woofer needs more room than that to crossover. Right now it is using a JBL Econo.thing horn that I picked up on from another thread. My living room is not so big, so dispersion is not such a big deal either.Ĭould someone recommend a horn (or similar) that will extend to the ~500hz region, allow relatively flat response in the extreme high frequency range without lethal beaming, and do it while not adding any new flavors to the brew? It is for a HiFi stereo that has been evolving for a number of years so the most important qualities will be the lack of coloration and the preservation of detail in recorded music. Teaming a JBL 2206H woofer with a 2426H high frequency compression driver calls for a horn, or waveguide.sort of device. Hi, I'm a new kid on the block and I need some advice.
