Romy If you would thank about what you are building and what it does, you would grasp the concept of my thanking. You have a 7inch hole on your bafflle with your woofer on the back side of it in a sealed box. The only presure that this device h...

Scooter, many houses in the Northeast were roofed by people who understand how this works, and the first few courses of shingles are "underlain" accordingly, to preclude such seepage.In Romy's case, I believe he could simply treat the entire horn lik...

HelloI've always wanted to try an ESL as a horn driver:So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.Horn is old closet that had a trapdoor...

[quote user="Horn Savant"]Before experimenting with the Hi power Electrostatic module, I used 416's in my large corner horn. They sounded extraordinary (ran with inf baffle to basementand made me realize how much Altec/JBL enclosures suck with their ...

[quote user="Horn Savant"] I then tested the two 416's in free air and they were 28 HZ each. Then I tested them in the horn - both drivers driven with signal and measured 23 HZ resonance. Better throat coupling - better than, say, a Shearer or Mirrop...

It is hard to see from the picture but the inner walls of the horns are not parallel. In fact there are no two parallel surfaces in the horn – that was the requirement. Some when any kind of roll lays on the section 2 or 3 surface then it is expected...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

Gera, is this an idea you're familiar with from a sonic standpoint? The horns are supposed to boost lower frequencies within their pass bands without adding their own sound, or - more realistically - allowing for their own minimal contribution to th...

Romy,When you say that the Vitavox 15" was the best midbass you heard, was it in a Vitavox corner horn? I'm think about acquiring or building a pair of Vitavox corner horns as I have a perfect room for them. ...

12” the Goto 4” how did you convert one into another? You would need a 3-4 feet

Yes, although the typical cork sheets might be too smooth and hard to apply. However if you were to crush the cork into granules... then apply to the horn, that should be feasible. Can you tell us anything about the picture you just posted? It doesn'...
