I still do not know if it will be doing at in my attic and I already bitch that I do not like something. Well, it is me… Considering the cost, objectives and the level how my midbass horn will be implemented (if they will) one could feel that it will...

I just wish before I start my project I read a few detail descriptions of the similar projects. Unfortunately they do not exist and I well understand that my project is in away an exemplary for the horn-minded people. All midbass horn are different a...

Probably not one subject among horn enthusiasts does not arouse as much fantasies as midbass horns. This subject in one way or another was discussed at my site (look for the linked threads) but I would light look at the subject of the Midbass ho...

I would like to share more of my troughs about the ESD
acoustic. That are not truly the troughs about the company but rather the troughs
that come to mind inspired by the company come to existence.
I do feel that it is an ultimate we dream of et...

Jessie, a few comments.
The back chamber mechanism is good. Are you planning to do the same in the midbass horn? Since you most likely will not drive your upperbass all the way down I think that the back chamber mechanism will be more effectiv...

Yes, if you have a midbass horn that more or less properly built then modesty and humility of the horn setup is the key ingredient of the horn sound. When I have my old transformer 11:1 then I had the midbass horns calibrated so perfectly that you ...

I is funny how my listening attitude is working. While my midbass horn is not built I do not listen music on my main system. I listen in via my MiniMe (Dunlavy 3) or in my headphones at work. At my home system I do not listen but rather think how it ...

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

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...

[quote user="Rewind"] I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression driver...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

Romy, what is your thought on using a Tractrix flare on a Midbass horn, Fc 140HZ then maybe a Le Cleah horn above, say 400hz. To me this looks on paper to be the best of both worlds and avoids the 1metre plus midbass Le Cleac'h horn.I am putting toge...

I need to say that with all huge advantages I have in my room with my midbass horns there is something that lost. I lost a great impulse response that I use to have on my old room with my direct radiating bass array covering up to 70Hz. I did not...
|
|
Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the le...

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...

I changed the new flash at my site to “Ok, the midbass horn project is successfully over. Over 3 months, over 400 posts, over 180 pictures… all publicly available…” The project started physically on July 16, 2010, ended on October 28, 2010. The prepa...

Since I got my stable and good quality electricity back I recalibrated my bass horn. Again, I set it up with very precisely and absolutely without any measurements, juts by ear, to sound exactly how I want it to sound. This is in a way my crown jewel...

Since I started this thread I have received a number of emails from people bitching that I do not like this, criticize that and that they can’t figure out what I do like. I reply to them invariably – “Do not read my site as you are too much a Mor...

I initially meant to put this post into my midbass thread (linked above) but then I decided that the subjects is self-important and it worth to separate in standalone thread. In fact this idea was formulated to months ago but I was holding to po...

[quote user="skushino"]My desire is to use a pair of bass horns for each channel, both vertically oriented, one each exhausting to the floor and the ceiling. I have an idea that spatial presentation will gain a big boost with both up and down firing...

Hi All,This is Ming Su and I am the US distributor for GOTO and J.C. Verdier. I thought that I will share with you about my new midbass horn. As you know by now, Jeffrey Jackson from http://experiencemusic.net/ help me on this project.&nb...

Thinking further about my "Hanging" inverted Midbass J-horn presented above I asked myself: where is to cut this 12’-13’ horn hypothetic horn. Initially I thought to do it in order to keep the parts smaller to be able to fit them through the doors an...

Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

[quote user="JLH"] Other than being completely ridiculous in appearance, this guy didn’t even bother to time align any of the drivers. [/quote]
This exactly what is the most fun in that system! Sometime people do not do the time alignment because it...

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 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...

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super t...

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...
