Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

Hi Romy,You wrote:"They tunes for 115Hz and pushed in room down to ~95Hz one channel and 150Hz another."So do your horns have 115Hz flare frequency? (and have the rear chamber tuned for 115Hz as well)From the pictures the horns lo...

Any LF acoustic system has two SPL levels: the SPL of pressure and the SPL of tone.[/quote]Ahhh! Very good Romy. I don't recall you talking about Pressure and Tone SPL before. The tapped horn can be designed any 3 ways....

These are some theoretical questions, I guess we can only build them and see, but some would be clear no no....

I do not completely agree with you. You see, I do not feel that stressing of “physics and geometry“or “scientific concepts” leads to anywhere. In fact I generally do not feel that knowledge itself worth a lot. I value much more a presence of a co...

Approximately a month ago I patterned the horn on the other channels and I have to admit the “tweak” is working. It feels as it acts as a sonic defogger minimizing some stray HF dispersions from MF channel. Generally the effect is positive but not hu...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

Wojtek,Can you tell us the size of the 204hz Azurahorn?I am pretty sure that the 550hz horn is around 15" in diameter. AH-425 is the model number. Please correct me if I am wrong....

Hey Romy,The Goto drivers (505TT, 100-8khz) and horns (S150, 150hz round exponential) finally arrived. I've only had them for a week so I can't say much about them besides they're not a simple drop in replacement of the previous 10" TAD woofer (200hz...

An irrational dislike of MDF drives me to other materials. This, from http://www.cfoam.com/, seems promising, and is theoretically cheap, though whether or not one can persuade them to CNC something for less than the price of an entire orchestra is h...

It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

There is a pair on eBay of Vitavox S2 drivers with 400Hz Tractrix StereoLab horns, the item 300372010439. I usually do not like to make comments about eBay things but I think it begged to be said. The driver and the horns looks fine for 1000Hz channe...

Ok, the story about the Red Wall is getting stranger …. Further thinning about all of it I came up with a brilliant idea.
The Red Wall has two air-conditioner wants. So, if the horns are built on the Red Wall then why do not make the rents … ...

I made a few calls to a few horn makers with a perspective to build for me a substitute for the horrible Altec 19 horn. While talking with people I was given an interesting lead about the guy that I did not know. He is a Canadian and his name is And...
