You're using a phase plug? Why? To try to get it to go higher? If using parallel drivers, and doubling Sd, it may be necessary to change throat area to not damage drivers... The third design type sounds quite differe...

Does anyone know where in the US I can purchase a new Electro-Voice DH3 high frequency driver (tweeter) and matching horn (perhaps the HP94--any suggestions?)? I can't find any vendors online that s...

[quote user="Joe Roberts"]The Manger is very different from Lowthers and other paper fullranges. It is very balanced and not peaky at all. Lowthers are lots of fun to experiment with but it seems the Manger is less idiosyncratic sonically, although i...

I once visited a Manger addict who had an active system with Mangers and corner horns (equipped with four eightinchers, not heavy pro stuff). I found the Mangers and the horns very well-matching, and one should be glad about every Watt...

A few questions. What driver is it? It looks like it is 15 Vitavox, is it 151 or 15/40? What the resonant frequency of the horn and driver with no back chamber? The most important: how the hell all of it sound. I do not be believed that you did not h...

actually this is not so much about horn loading ribbons as it is about curving them, but also horn loading. look at this horn: http://www.pioneerelectronics.com/pio/pe/images/portal/cit_3442/35960TH-4003_s.jpgnow imagine a ribbon of approximately sam...

Hey Romy,Goto makes 12" and 15" woofers at 100db. I recently found out they make a small two way system using an 8" woofer. The 8 incher's range is 55hz-8000hz so I'm thinking it might be a good candidate for use with 60Hz horns. Looking at Goto's 12...

I understand your point of view concerning 'vintage' in comparison to 'contemporary'. What I find the most troubling with many of the present/contemporary attempts in design is that many people claim to have a truly horn loaded system capable o...

I concur the objective to acquire performance in the desired frequency range must predominate most other considerations of design.My objective for the design of the mid/upper bass horn is to attain effortless, smooth, real-world horn-loaded response ...

The KOSS Electrostatic unit was still installed , so I removed and checked resonance .The resonance was 136 HZ. I then tested it in horn assembly and the result was the same : 136...

I was thinking and fantasizing about finishing of my midbass horn. My first idea was to paint it internally with the same color as my cathedral room. Perhaps a lighter grade of paint in the end as the horn goes dark. As the only mouths of the horns w...

I spent today couple hours to walk around my fist mouth. It is juts test-jointed with screws, not glue yet and it responses horribly to knocking. We put a few 2x4 brasses and frames. It looks like it will be 8” between the 2x4 and it will become some...

You might want to try covering a section of plywood with the modified cement/mortar recipe as a test before you write it off as too difficult or too expensive. Basically, it does pretty much what you ask, and it need not be 2" thick, either; 1/2" or...

[quote user="RF at Ona"] Personally, I think it debatable whether the mouth edge should be free or attached as there are desirable aspects to both approaches. If attached, it need not be attached with great pressure. [/quote] Robert, can you elaborat...

OK, on Monday my carpenter will do all necessary work to fine align the horns, to tight and to solidify what need to be. The framework with horn will be over and on Tuesday he will cover the things with sheetrock (drywall) and begin to apply the fin...

what you did in your horn : you coupled your horn and you added mass on cone. then imagine when the cone tried to make an impulse it moves forward and then in back chamber something stops it from moving(air pressure+-) your driver had been stopped fr...

Discussing the Jessie project we multiple times mention the idea of the large midbass horn handing above MF section. Where else the 7”-9” might be positioned? The rational was to have it positionally contra-react the output of the upperbass horn. It ...

Neil, I hadn't thought of it that way-- it would save money, only have to run one wire to each midbass too! You're too funny! The link Romy posted earlier: http://www.6moons.com/industryfeatures/vsac20082/vsac.html shows the throat.&...

I was thinking about a space-economical way to arm playback with midbass 50Hz horn. It is not that I am into it myself but conceptually I was wondering how to put all of necessarily things within a minimum compromise in minimum footprint. I came up w...

I am not and expert in wood construction, all the building we do around here is brick and mortar, but, If you get the Horn wall close to the roof you could fill that space up with that spray expanding foam. The side of the Mid bass horn will be sti...
