I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...

Thanks for your comments, Romy.Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems ...

2) I do not think that you will be able to time-alight the upper bass channel but you need to wave-align them. Make sure that upper bass and MF tit the top of the wave at the same time. the w...

[quote user="jessie.dazzle"] There may be better drivers out there, but with my level of experience, I doubt my abilities to recognize them. So though it may resemble laziness on my part (remember, this is the same person that will be constructing a ...

Here is the update as recommended by RomyTheCat, the listening position is about 4 m from the upper-bass (I think it may work depending on how the >50 Hz mouth end up) and I also become creative with the bar. :-)Do someone eventually know what wou...

If we conditionally accept that the word “High End Audio” means anything then the High End starts from the upper-bass rigion ....and then refers to the balance between the upper-bass and the upper mid-range. If those two regions of Sound are taken ca...

"The top response of the upperbass channel is challenged. I do not know why it is – a wrong driver, a wrong curve in J-horn or wrong made filter… "
That sweep mirrors what I hear - specifically tepid and weak upper bass in the presence region betw...

[quote user="Kerry Brown"] Bruce says his folded upper bass horns work much better though - and he's usually right...[/quote]Well, let do not contaminate ourselves with superficiality. If Bruce suggests that his folded upper bass horns works better 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...

[quote user="jessie.dazzle"] Are you suggesting : 1) Running the upper bass horn from a second ML2 ? 2) Running the lower bass enclosures (sealed boxes) from a second ML2 ? 3) Running both the upper bass horn and lower bass enclosures (sealed boxes) ...

I too want a monitor speaker to play with, especially for amplifier experimentation.I put another 4" Fostex in a sealed "box" (globe actually) and crossed it over at 150hz to one SS 25w/8565 on the side. Wishful thinking? -Yes.About 88-90dB sensitive...

A friend of my told me a couple months back that CEC introduced a new version of their top of the line transport. It was kind of strange as CEC was abandoning to manufacture TL0 for years, or it was at least what they were claiming. Then I thought th...

[quote user="peter foster"] I mention this because your comments about Playlist 07; Song 02 and Song 03 are difficult for me to reconcile. On my system the upright bass is heard with very fine detail and all of the complex harmonics that follow...

Danvprod, I hope you understand that “proper four or five-way system” is some kind of Unicornnish type of animal and we could talk about it only abstractly. Still, since you have mentioned it – what and how are you trying to accomplish with your five...

You and I now have what seems to be very similar situations; similar MF and HF channels, in a room of similar size. However, I still have no operational dedicated mid-bass channels; you do. I have dedicated lower-bass channels; you do not. As is ...

In considering integration of my own mid-bass horns, and how I'd ideally like to do it, I too passed by the underground, up-firing solution, and very much like this approach. I do however have a preference for inverting the concept, resulting in a do...

[quote user="Vasyachkin"]has anybody tried a horn speaker with a dipole bass section ?[/quote]Well, I must say that I have tried dipole bass in a few configurations, including dipole bass plus horn, however I think this is completely immaterial to th...

I was rushing when I made the last post. Wanted to share a little more about my thought process and how I arrived at doing another large-scale masochistic audio project. Making a bass horn is a huge risk - the results can vary from exceeding expect...

Quotes from Romy in blue: "...Anyhow, I do not know at which stage your project is what I think you are somewhere in a process of integrating the drivers..."I would like to stabilize the system, and listen to the existing horns, while ...

Merlin, I wonder why you need more information if according to you: “the solution that has not been heard and is not intended for your ears”. You migration from sightless denial to desire of self-education is very… I would say fast but st...

Drdna, generally I would not agree that your assessment of the EdgarHorns is correct. There is nothing fundamentally wrong in them that would prevent them to "disappear" in the room. [/quote]Well, this is good news.&nbs...

When you say, your horns are 11feet apart, does this mean from acoustic centre line, or the outside perimeter of the upper bass horn. If it is from the outside perimeter of the upper bass horn you are having a similar setup with mine. When they are a...

This is our first offering; we are indeed working on another two higher priced models. One will have an additional channel on top, the other one will be front horn loaded down to 40 hz. Optional finish and colors, both for horns and supports, a...

Angelo, I do not think this site add anything applied to the subject. I personally do not feel that upper bass horns require any phase plugs; quite in contrary they are dreadful for upper bass horns. When a straight horn employed then the horn does n...

Thank you Romy, I wasn't aware of the 30 day trial...I though only PS Audio had this policy with power regenerators...The 25% load is a nice tip, thanks again, I trust you judged this value according to personal tests and measurements. The sad news i...

[quote user="Romy the Cat"]I do not understand what does it mean. Are you saying
that you lost bottom response with closed exit hole on the driver back? If with
the closed drift from back you have a (loaded!) response no lower than 200Hz then it i...

Skushino. Yes TH is designed to play 2 octaves and no more, this derives from the design which actually uses a labrynth, in the shape of a horn, to return (and amplify) the back wave of the driver to the front and add its strenght to the output, no...
