The EBS alignment gets its name extended bass shelf from the type of response curve it gives. Response falls off up in the midbass or midrange and stays at this reduced shelf down to another point where it rolls off rapidly. So what you gain in extensio...

Re: Favorite flavors
Very good points. Good points indeed.But I will be very honest. I think the attraction of some of the round horn designs of the last ten years or so is mainly hype. I think some of them are attractive in an eclectic way, sort of retro looking and cool....

Re: Corner Horn Recommendations
There are two big advantages of the π cornerhorn configuration. One is the efficiency increase offered and the other is directionality is matched from the lowest bass range up when 90° HF horns are used. This creates a uniform reverberent field like no ...

Re: Favorite flavors
There is some debate as to whether reflections are good or bad. Reflected energies give ambience to the sound, albeit an artificially generated ambience. On the other hand, reflections cause intelligibility problems and response anomalies, so too much o...

Re: Favorite flavors
WayneThese two comments are not true."But the listening area just becomes too small. The reverberent field is usually non-uniform too, since the highly directional nature of a narrow HF horn is very different than the non-directional LF energies produced ...

Re: Favorite flavors
Hi Earl,I like using 90° flares in cornerhorns because the angle of the horn flare matches that of the walls. That's really an ideal solution because the low frequencies are directed by the walls and those higher up by their horns. Everything is matched...

Favorite flavors
I'm looking to get some opinions on favorites, specifically horn shapes and dispersion patterns. Or, for that matter, if your favorite configuration isn't a horn, I'd like to hear those opinions too. But more importantly, I'm looking for your reasons wh...

Re: JBL sub1500 corner horn?
That is a nice woofer. It works well in sealed cabinets, and is not underdamped (peaky) in even very small boxes, down to 0.5ft3. However, bass response isn't good unless the cabinet is made larger than at least 1.0ft3, where f3 is 60Hz. In my opinion,...

Re: Bandpass subs
Two things that are nice about corner placement are that room modes are energized equally and also that you gain directionality efficiency from π/2 placement. The corners become very large conical horns, similar to rectangular horns with 70o flare. I li...

Re: A few words of endorsement for Headphone Systems
Hi Gar,That's cool. I agree with you about headphones. I also agree with Mike Baker about sound systems outdoors for a similar reason. The sound isn't influenced by the room and all the stuff inside, sound bouncing everywhere. It just sounds different...
