I have 2nd order crossover both on the upper knee of the ob bass section and on the lower knee of the midbass section. My measurements show phase response and the summed spl is as good as it can get. Have you tried the direct servo technology or do y...

[quote user="Wojtek"]You mentioned it yourself that the most interesting midbass you ever heard was from corner horns. Why not utilize if you can a pair of K-horns (or clones) bass (midbass really) bins with sort of moveable fake corners? They can be...

From the time of the insertion and setting the proper crossover my midbass is growing and growing, getting larger, deeper and better in all aspects. I am not kidding and now, when I have no ULF channels operational, it is very obvious. I can’t explai...

[quote user="green heron"] I'm happy with my results midrange on up at the moment, but I'd like more slam from the midbass horns. The backchamber may be a bit too large, so I'm planning to experiment with the cabinet volume. Do you have any su...

Moron it is then...Anyways, seeing the back chamber of my midbass horn, you would say that its way to big, no? And you would recommend me to proceed with a similar tuning process as you describe in this link?http://audio-db.info/AudioDB/BazaPraktiki/...

I am sorry there is a mistake in my previous post, anyone who has played around with a dedicated channel for a 40 to 200 hz frequency know hat the only sound coming out is a wooo, woo, woo... Not much to do listening test by, we can measure, but te...

I do not know the “USSR made 2A9”. My feeling is that all USSR-made driver were crap but who knows, might be three is something did exist in there. It is hard to presume that if the guy changed from dual GOTO SG146LD to basically direct radiators wit...

[quote user="Jorge"] I need to care just one octave at my 25Hz bump,I have tried the same solution in a big room, the thing is that we not only got output at 25 hz, but a lot also at 50 hz! There was no way surgically cut it to what we needed and the...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

I was listening recently my Carl Schuricht’s Bruckner and I again noted what I am been noting for a while. I feel like my Midbass horns begin to sound a bit saggy. It is not too but and the degree of change is very minor. It is not even auditable...

Tubebuilder, I am not sure what you are trying to do. According to the “Romy’s Rules” (whatever it means) people do not build Midbass horns but they build an installation that might include the Mid Bass horns. You do not need to choose a project jus...

With Ming permission I post a fragment of his emails where he describes his midbass horn. It appears that he uses cone-drivers with ltooooooo ow Fz in non-compression application with no back chamber. Now it is obvious where he is losing his midbass ...

Hello Macman,Nice horns, I like that you finished everything properly! I am getting tired of seeing piles of horns.I think the ringing you are getting from your midbass horn is that the throat reactance is not balanced. How did you calculate the ba...

Jessie, there is another solution that you might consider, that might be viewed as compromise for one-side as might not be view is compromised from other side. If to allowed ourselves to close eyes to midbass timing-integration and if the geography o...

[quote user="Rewind"] The Fanes are the most detailed midbass speakers I have heard without a horn, but with the paper horn the detail was gone. [/quote]I am sorry you are naive. Fanes are not too detailed midbass speakers. Also, of Faned have lost w...

Dear Romy,OK, some more about the midbass.Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than w...

The mean KOTriode in his thread “A different breed of 6C33C amplifier“ jinxed me with his 6C33C vulnerability and today my output tube at right midbass channel went down. The characteristic pings, which via the midbass horn sound like house room is c...

user="noviygera"]Romy,
You make
very, very good points now I am re-evaluating this all-in-one horn concept. I
do know one thing that I learned from my current system. Midbass horn that
rolls off below 120 hz and integrated with sub is not...

Besides hornresp modeling, is there things to think about when starting design and build of midbass channel from scratch? The range I need is 60 to 300 hz. It will be used with 6db/octave crossover. It will be located under my midrange horn -- the mo...

First off, I forgot to mention an interesting observation: Before running the sweeps (previous post), since the drivers in the upper-bass horns are new, I decided to verify/optimize rear chamber volume (they are easily adjustable)... I wasn't expecti...
|

Thanks Romy,I was hoping to hear that you remain happy with your midbass solution and was surprised at the time about the small cabinets that you used for the Vitavox 15"ers, but having measured T/S parameters of the drivers here I can see that indee...

Thinking about the integration scenarios of my midbass horn I come to a realization that it highly possible that the horn in THIS room will do something very unique. I have wrote before that I was successful to set channels delayed but the delay ...

I have just started thinking of something like this for midbass/ULF: floor firing one-eigth horn (TuneAudio Anima inspired) with the scanspeak array (in green) attached to the side.There is the obvious problem of time alignment, but I can see no wa...

If you look that Jeffrey Jackson’s midbass horn then you can see two pillows stuck into the horns belly. Let presume that the pillows were placed there in purpose. So, here is homework for people who would like to flux their horny mussels: what is t...

[quote user="TonyB"]Romy, what are horn flare frequencies of your horns? I understand that both are Tractrix. My guess is that the midbass is 125Hz with a sealed rear chamber and 4" throat. Correct? [/quote]They tunes for 115Hz and pushed in room dow...

I would like to add this driver to a good driver list:HiVi D10G 10" Kevlar/Paper Woofer, it is sold at parts-express.com and it was one of a few drivers that I ordered for a personal shoot-out. Ignoring the fact that it is yellow and that it makes hu...

Of cause I can pull the midbass to over the carpet and I can tuck more rug under the couch but I have completely different things to negotiate now and completely different objectives to follow. Tucking more rug under the couch would not work as “rug ...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

The room is beautiful, and I love the tree stump "rack" with the amps, it is clearly a work in progress, but they already put in the "Western Electric" badges on! It talks a lot about their priorities I guess!They have what seems to be a midrange ...
