hello again Romy, cats, friends...
I built this horn for Ming Su, the Goto USA importer... I have posted on your site before about midbass and bass horns... I listen to eight foot straight 45 Hz horns... and as partial payment on this commission ...

Hello Members,i am new in this forum,and want to share my experience in horn building until 1980,my newest construction feature isbass horn mouth distance and membran movement cross settingby my new double horns....

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

BTW, purely hypothetically, Jessie, if you have a long harrow room then did you consider to put your bass horns vertically, facing them mouth up, pretending that they are large vases? It might be a new kinky surreal home decor and you can make the th...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

Yes, I should have said modular like your bass horns, but with much smaller segments, e.g. 36 segments of 10 degrees. Assuming one keeps the profile the same, the only difference between different sized horns is scale, so a single mould "capped" at v...

I kept thinking about cats and cat food (also known as birds) listening habits this afternoon. That's why parrots bob up and down, as well as (less often) twist back and forth on one leg sometimes-- to triangulate and pinpoint a location in all...

Room is extra nice, better then most i have seen on the web. We all will hear from you telling us there is no bass, in your new room. It looks like 300Hz down will suffer because square footage increase like 10 fold from last room. You will have much...

I will be dubiuos about the slanted enclosure if not done properly, all drivers must be time aligned and since they are playing the same frequency, deficiencies in time alignment become more obvious. I made a slanted enclosure but with the drivers ...

Khorn has about 2meters path length so they have to be positioned closer with false corners in Romy's case to be aligned. If they are at the back one has to add the distance from horns plus the path length of the khorn bass bin and delay the rest of ...

Well, yes... I've not been to prison in over two years! Apart from keeping me off the streets at night, the results when listening to one of the 40Hz horns were, dare I say, encouraging, though I do hesitate to say so, as the "evaluation" was carried...

[quote]might I ask why[/quote]1.)the bass will be pretty coloured...mouth not large enough for proper bass response..
2) numerous horns--imaging all over the place!
3) All those tubes in the mouth of the horn??? disaster..microphony!
4) those horn...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...

[quote user="Horn Savant"] I think it's about the same as free-air resonance - backwave to entire basement. Precedent: pre-war theatre horns(open rear like Shearer/ERPI)(unlike post-war reflex tuned designs like Altec A4)(I don't like reflex boxes - ...

I pulled a mono set of these exact looking horns out of a movie theater they were installed in 1946 :)the system consisted of 2 of these bass cabs and one gigantic dual compression driver horn on top for the entire theaterI am no horn guy and looking...

Rewind, this is funny because it is not at all terrible. I have thought for some time I would try paper mache "wings" on a WR driver, but I've never gotten around to it. Believe it or not, your little demonstration has rekindled my interest.At some ...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

Hey Romy I read your requirements of a mid bass horn. I am using jabo tratrix KH-55A(320hz) with altec 288 and I want the mid bass to go under that. I would use a trattix round midbass if it was possible. But it's just not with in my abilitys to buil...

I would worry that there could be an interaction between your electrical filters and the filter formed by the horns themselves.I, too, like to trust my ears and I would ten to trust yours more than mine but nonetheless you have created quite a compli...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....

I confess that at one point I tried PM6As in 2.5 cu. ft. vented boxes. Lousy, tipped-up balance and soggy, one-note "bass", contrary to the designer's claims. The only thing good about it was that the box did not add c...

I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you. Let pretend that I went for exponential midbass profi...
