Spend a good few hour moving the boxes, connecting the cables
and do other sort of things. Was looking for elegance and more symmetry. The
objective was to put midbass channel between the main horn islands and set the
horns, the midbass and LF in ...

I meant to have this post as a separate thread in the “Playback Listing section “– the “load” of it is well-deserve it but then I decided that it would be too easy for the readers of my site. The subject of this post is well related to results of...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

[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...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

A few days back an audio guy from Mexico-city visited me from. We did listen some music, talk a bit about audio. As usually I interrogated him about the problem he hears in my sound. The people who were in my room know that I do it with absolutel...

Well, I guess I have to pass some observations about the new Living Voice Vox Olympian.
I did not listen them, did not talk to the people who behind the Living Voice and all that I know about them are the Six Moans articles and a few threads ...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...

Ok, I will share with you some ideas that I have in my head how to deal with horn decay asymmetry. They are in a way the further development of the Haralanov’s idea of acoustic diode – the brilliant concept from my point of view.
Before I will...

Below is how my midbass horns feel in my listening room user normal lighting if evening listening. The horn look a bit too dart but they are the same density as the walls in the room. The horns feel darker because the Triangular wall is all white, fr...

de Charlus, this “are not afraid of cabinet resonance per se” is complicated subject. I have raised the topic in the “How to USE “Resonating Oops” in loudspeakers” thread:

[quote user="haralanov"] I think you have found phenomenally good sounding upper bass driver and you are going to build a dedicated quasi-bassreflex channel using it to fill the gap between your line arrays and the upperbass horns... [/quote]

Well on the upside, I suppose midbass woofer cost is reduced by Half..Seriously though, I'm curious what shape throat and woofer (or driver) Jeffrey used in the ~50Hz bass/midbass horns.Neil...

Excellent news regarding this morning's discoveries. jd wrote:"...Are you able to say whether the problem is due to the horn position relative to the room, or to throat diameter relative to the driver diameter?..."Yes, a stupidly phrased question, bu...

Mani, please keep us posted on your impressions of the bass and midbass. They look wonderful! Are they both in the corners of the room ? Could you please give room dimensions with seating position indicated? I would be very interested in hearing mor...

By the looks of the earlier photo, you will be bringing the LF and midbass channels quite a ways forward, perhaps 3 or 4 feet, but it is difficult to judge distance from the image. Will you have enough room for the midbass boxes to snuggle in beside...

[quote user="Romy the Cat"]Simply beyond any criticism. The Purepower bass was something that sold me on the very first unit in June 2007. The very first Purepower 1050 had the same type of bass. What kind bass? Well, if juts did not “improve” it and...

everything is there!was so focused on searching s2 and midbass i did not realize that you gave macondo a seperate section.was slightly off yesterday anyway, my friend crashed my motorbike, wanted to ride it to italy next week:-(anything wrong with a ...

A site visitor sent me emails saying:
“Johan Dreyer says he can hear no time delay with his bass horns…”
Well, first of all I disagree with it. The fact that Johan Dreyer can hear no time delay is not an indication that delay is n...

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...

I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....
|
|
RobertAren't those meant to be driven by 250W SS amps ? Did you chose driver for your midbass already ? I thought that for this range 8" Lowther DX series with its 50Hz Fs and its "lean" sound could compliment your GOTO drivers (16 Ohm version has 3m...

Hi Romy,1) What dimensions for 1808 baffle would you suggest? 2) Is floor-firing vs. front-facing cone useful or preferred?I believe you wrote LF channels should be placed in arc outside midbass channels. 3) Any *general tips...

I stopped by today in a local warehouse and picketed a 4x 16” fiber pipes and 2 two 20”. I absolutely love the effect. As soon I brought the tubes to the room and took the cover off in the hall room turned to be much quieter at HF. I did not expect t...

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...

but I'm not going to compete with "S2 people " Following recommendation of John Hasquin I ordered B&C 21EP8 -16 . I'm cured form Fane for a time being and don't have S2 but "obsolete " altec 288c 24 Ohm on 400Hz horn . I was counting ...

Gera, if you would
like to incorporate the Western Electric 13a with 555 then you need to make a decision
how low you will drive it. You chose the 120Hz but it might
not be useable frequency, it might be much higher in order to get “better”
sound...
|
|
Yes, Jessie I have thought about it as well but whatever you do with 40Hz horn you end up with horn talk with each other. It is very simple to measure – use one as a transducer and put a measuring dB meter across the VC of second driver, treating...
|

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...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...
