Thought 2' drivers were 'THE WAY' to go Much more powerful than smaller ones.

Claude said DO NOT USE A 2' DRIVER with this. Hopefully you 'experts' A , A , and others can shed some light on this for an amateurġ. Yes, was looking for a horn slightly smaller than a K-402 (Have 510's with K-691 divers, and want a 'larger' one but the K-402 is about 4 inches too wide for my setup ) So was interested in this ME464 horn also.Ĭouple of things I do NOT understand. I simply dunno what to think, if diffraction slots are harmful of interesting thread.

Maybe this is due to working with straight sided conical MEH's so much, trying different secondary flares.īut even on something like the well known elliptical XT1464, a CD to throat mismatch has made nearly no difference compared to the effect of the baffle or box i put the horn into.Īlso use a RCF HF950 with a diffraction slot which measures and listens very well. What i find very puzzling with the horn measurements I've taken, is throat anomalies such as less than great CD-to-throat matching, diffraction slots, etc.seem to matter less than mouth termination changes. 'constant directivity' horns-which is the reason why most of us here don't use that term any more in favor of the term 'controlled directivity'.straight-sided horns without slots in the throat-like the K-402 and the K-510 series, etc. The horns with slots that cause frying bacon sound are like the old Altec, etc. I tend to avoid slots in throats, but that's because of the poor experiences with the D.B.

I think that there is a range of designs that are 'happy mediums'. With the old Keele constant directivity horns, goes too far in the other direction. With OS throat horns, I think Geddes goes too far. So it's the degree of HOMs that are generated that is the issue. That all reminds me of the old JBL horn lenses of the 1950s-70s, that were eventually abandoned in favor of slotted throat and baby butt designs of the 1980s. the polar coverage of a 2' throat horn above 6 kHz is most strongly a function of the driver's phase plug design, and not so much the horn-unless you stick a throat lens in to spread out the polars (like Roy is proposing with the 'new Jubilee'), but then you've got some big discontinuities in the throat again like the old constant directivity horns, and those old horns don't sound very good above 4 kHz (i.e., the horns having 2' throats). Make no mistake-the OS throated horns have problems, too, especially because you really can't listen to them on-axis, i.e. I'm aware that OS throats also have their issues (that Geddes talks about.but not as if they're defects, but rather as '.well, you don't want to listen to your horns on axis anyway.', which is BS). I always hesitate to talk about this issue, because then all the Geddes 'HOMs' people tend to appear to poo-poo any discontinuities in the horn throat, in favor of 'OS' (oblate spheroid) throats.

The horns with slots that cause frying bacon sound are like the old EV, etc. Haven't heard any frying bacon yet, but all my listening has been done fully processed.so that might be a factor.
