I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA horns or horrible acou...

The Delta Pro-8B looks like a very fine driver, in fact on the paper it is even better then Fane (with exception of sensitivity and inductance) The problem is that no one knows how this driver will sound until it is loaded into a specific horn, no o...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

I'm also of the opinion that the bass is one of the most critical and most challenging parts of playback. Not talking about quantity, but rather the quality of bass reproduction. My approach has been to split the bass in two parts - Low and...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

Dominik, Jessie is right - it is irrelevant the precession of your profile if you horn does not go to high into HF. The LF gain of upperbass horn happens in the first half of horn anyhow. I do not insists that I am right but I have a hypothesis that ...

I spent some time with my back chamber, trying to drive the driver resonance heighted. I built a sealed sarcophagus as a back chamber (if somebody are interested I can post a picture) approximately 1.5 gallons but it moved Fs for 700Hz. Then I began...

None of the commercial speakers might relay on the Imbedded principles because the obvious reasons. They always look for as neutral as possible location because they mostly designed for anechoic operation. However, if the Imbedded techniques are used...

[quote user="skushino"]My desire is to use a pair of bass horns for each channel, both vertically oriented, one each exhausting to the floor and the ceiling. I have an idea that spatial presentation will gain a big boost with both up and down firing...

[quote user="Romy the Cat"]My right bass channel that that sited right next to the equipment bay has no bass. The left LF channel is sitting in a very good “hot” spot but the right is in bass hole. I would need 6-8dB of extra gain across the ent...

In reference to the two (or three) prototypes, the base design contains one (1) driver, a second proposal to the base design uses two (2) drivers (using almost the same exact enclosure--an increase of volume/area in the chamber containing the two [2]...

Hello all,Some time ago, I bought a pair of very early production ML2s for an ongoing horn project (see "Note at end").Rather than just let the ML2s sit and wait for the horns to get done, I of course tried them out with my "normal" 89db/watt@1m spea...

Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.

[quote user="noviygera"]And one last thing for now I'd like to ask you. Would you know of a builder in the USA that can design the horn based on my requirements so that I do not attempt to be a horn designer? I can get the design built locally.[/...

It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...
