I was waked up this nigh with very load sound of thunder and lighting. The rain was gashing and I went close the left opened deck doors from last evening. Suddenly, totally out of blue, and idea come to me – why do not use the idea of Carlson Enclosu...

This is a pro audio company that came out with a nice looking system, supposedly they are more about SQ than others:http://www.voidaudio.com/product_detail.asp?id=42...

Looking that my attic place is very much triangle I am contemplating an experiment with triangular horn. The idea that lead me there was Balalaika. Balalaika is Russian 3-strings musical instruments that has unique sound. One of the attribute of ...

I would never believe that I would face this problem. My carpenter measured up all my space and give me a verdict that he can put in there two mouths 4 by 6 feet with a foot and a have between them. That is it and that was exactly what I would like t...

Today a brilliant and insultingly simple idea come to me. I was thinking about the way jointing my sections. The horn probably will be made by 2-3 sections, plus the transition please. So, the section jointing flanges are usually made. I probably go ...

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...

The units that i put in my pictures JBL AND ALTEC A7 both designs have a resonance just like all wood that you would rap your nuckels on even 2 inch thick plywood will resonate at a given frequency, that goes for glass, cement, metal, they all do...

I realized that this thread is slowly becoming the most sophisticated web recourse about Midbass Horn available. Trying to keep the thread educational I would like to introduce to my readers one more objective of my project. The subject is super ...

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"] 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...

[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 ...

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...

A horn basically directs acoustic energy in a single focused direction, maximizing the efficiency with which the air mass to moved by acoustic waves is coupled to the driver. The best thing is to read a good book that covers the basics in simpl...

I heard a friend's horn system recently and was very impressed. I don't have the resources to put together a diy system as discussed here, amazing as they seem, but am looking for recommendations for commercially available finished horn speakers that...

Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the acoustical length of ...

Paul,I have not heard the synergy horn or any speaker with that design. Here is what I am talking about:http://www.yorkville.com/images/products/u15_cut_sm.jpgIn this particular case there are 3 mids and 1 tweeter driver sharing the same horn.This so...

[quote user="noviygera"] I am NOT talking about single wideband drivers or any back loaded type horns. I am talking about properly made front loaded horns. For example, the Danley Synergy horns, that use single horn with multiple drivers to cover a w...
