Got the ultra low DCR toroids coil and pit them in use. Yes, it was very right move and they a bit trimmed the midbass tail. Playing with inductance and listening how the midbass decays (measurements are worthless in this case) I ended up with 4.8mH ...

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 ...

[quote user="msaudio"]I have built quite a few bass horns and found any thing over 1/2 inch ply wood reinforced is all you need, in front of your baffle. If you had ever built a few on your own and had the right equipment to test you would realiz...

[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...

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...

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...

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 ...

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...

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 good. I have struggled with t...

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...

Say whatever you want but some of the vintage drivers has
it. Not all of them but some of them do and the question how to get it. I

now but there are some topological ...

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="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...

Thank, Manolis, it did address some concerns. I think I even know what you did with the MF driver. You were able to get 50Hz out of this looks like horn? This is impressive. The boundaries-loaded horns sometimes allow doing away with the horn siz...
|
|
I realized you meant Midbass when you wrote MD. I agree that letting the midbass horn run full range on the bottom is not a good idea. My point was try the bass channel (Aura 1808) run much higher and share the same crossover as the midbass when cros...

Today a guy I know from south coming to my listening room to hear my payback. He is mingling with horns, he heard my installation in city and he is very much interested to hear my new listening room and the most important my new midbass horn. He actu...

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...

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...

[quote user="Antonio J"] INTEGRATION that's the clue and that's what I always feel lacks in my room, I mean extreme integration, real integration, the feeling that the recorded bass sound has its own boundaries, not my room's. [/quote]

Jessie, I have moved your post to your 45Hz horns thread but then decided to keep it here as some of my comments would be about entire system not only about your midbass horn. Anyhow, there is nothing there to laugh and it is pleasant to see that som...

I asked Alex who got those tweeter from him and he said that it was Stavros Danos from Cyprus. So, it was the Greek guy that we have meet before on the pages of my site:

Jessie-Good to hear from you. I am very motivated following your progress. Thanks for the inspiration.My room size is around 15' x 18' x 8'. At this point, I feel that a proper 60 - 70hz midbass horn is physically the largest I am realistically pr...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

Sure, I’m very much done with Macondo and the late frame is the last straw that I load to this camel. It took 60-7 years come up with where Macondo is now and I do like how it turned out to be. In a week or so I will be done and I will post the pictu...

OK, this morning I tuned the playback and did some listing, trying to understand what was the problem. Sound was not just bad but it was very strange, it was almost as a mechanical replica of sound. I took my phase meter trying to set horns in ph...

Rakesh,Thank you for your kind remarks. I appreciate the close scrutiny you have given my previous post but I think you are at a stage of system design where many basics of your system should be considered and evaluated before the issues of my po...

As we are looking for our new home I am slowly simmering in
my mind the ideas about new midbass horns. It is not that I am short for ideas
but I am not sure that I will take my family on a bumpy and costly ride to build
new horns. One way or anoth...
