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...

Hmmm, are you sure that you do not do a mistake?
Jessie, I do not know how to say it but looking at your last picture something does not work for me. The hone that you made are elegant and graceful but painted in glossy black with that very rough st...

[quote user="serenechaos"] By “midbass horn” I’m talking about a horn with about a flare frequency of about 60 Hz, to use with Fane 8” drivers, to start with.

One more thing I would like to add: what if despite of the oversized throat problems we have a task (as you, NL, proposed) to use the overthroat horns (overthroat - horn with oversized throat size, let it be one more Romynizm). I think the dealing wi...

[quote user="Romy the Cat"]I stepped away from the idea of horn tweeters. A horn is equalization devise that boost lower knee. If people need to spread a tweeter in MF then it is OK but in my case my tweeter sits at 12.5K and I do not need any gain a...

There is a guy named Ad in Netherland who makes looks like aluminums (but I am not sure) horns for 1.5 inch compression drivers. The first picture it looks like an exponential: W=39cm/15.4Inch. L=45cm/17.7Inch.
I do not know if Tractrix and the Fren...

Ok. I have some very good results to report. I've been stuffing my midrange horn (250hz lecleach with BMS4592nd-midrangeonlyversion) with some 20-hole-per-inch open cell foam. As per Mr. Geddes. Its not coming out. 1. I can now play louder with no sh...

Regarding vertical convergence :
I have often wondered about the effects of arranging horns vertically, such that their output converges relative to each other, toward a single point at a given height above the floor. I have seen Wilson Audio do...

What surprises me that no one express interest to the idea of making a bass horn with a fifteen incher. Many people did it, many peoples what to do it and most of their efforts were not successful sonically. The really is that to make a good sounding...

[quote user="jessie.dazzle"] Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling... I woul...

Thanks RomyI appreciate your advice re non single bass horn.When you say, 'good luck with a smooth response from 25Hz,'...does that mean it's not possible to get a smooth response...or, it's not so important to get a smooth response...?A friend sim'd...
