[quote user="Joe Roberts"] Interesting concept but let me point out a few considerations.
The diffusor does performs a mild "equalization" function if you want to call it that but it is also an aid to dispersion. It is light "EQ"...3dB might be abou...

[quote user="be"] "another big selling point to me was the 505 being a low resonance compression driver.. there just aren't many drivers with a resonance in the 80 to 100 Hz range like this driver... I have just begun my playing, but am already quite...

[quote user="be"]I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, ...

[quote user="Jeffrey Jackson"] so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet of plywood) and have a mouth roug...

Hi Romy, hi folksMy intro hello and first post, i just had to sign up. Just found the platform through googlin some hornstuff and came back too often.Especially the resonating oops was the latest topic that really cought my attention as im familar, a...

If you are going to build such a huge cabinet or put a hole in the floor to use the basement as a chamber, why not just build horns in the basement with a straight 8-10 foot section in the basement with the back chamber resting on the floor, cut...

I had today a long listening session. I listened a whole Mahler Second and I can tell you that I was the best upperbass I ever heard from a playback. I am not kidding. The upperbass literally despaired in the new room but what it is being called up...

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="Max Shatsky"] I find the playing by Orchestra of the Age of Enlightenment as the most boring, sorry, I don't get it. [/quote]
In my view the Orchestra of the Age of Enlightenment’s play it not boring but rather not flashy and not overly...

...deletd.The Mahler Second last Saturday was a wonderful concert to demonstrate how irrelevant BSO is becoming in lives of people who are interesting in actual musical results instead of paranoiac desire of feeding a parochial cesspool of smalltalk ...

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

[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...

Yes, the crossover looks fancy :) More than that it does the job. The vacuum caps are only for the tweeter and the upper-mid beryllium. Still they are bridged with micas as they wont do much alone. Adding vacuum caps smoothens the transitions and sou...

Maybe, some people would be interested in what I am doing with my system. I have been continuously listening and sparsely making changes and letting them sink in. For now, I feel more settled and think the biggest obstacle for me in reaching the ...

You need to decide what length of the horn you can afford. When I mean “afford” I ment the position of the horn in context of the rest of your system. You know the lowest cut off - 40Hz. So, the most suitable for you length and the mouth size will gi...

Yesterday I spoke with a guy at a Russian audio forum who reported that he played with addressing many problems of compression driver by pumping ferrofluid in the gap. I am not a big fun of ferrofluiding generally and in case of compression drivers i...

[quote user="Paul S"]Romy, is it a goal to make the horn strong enough to raise one end or turn it without having it fall apart from its own weight?From your earlier descriptions, I expected to see at least one continuous piece of plywood bridging th...

OK, now I am happier as I did my duty and the back chambers are ready to be attached to the horns and to be lifted up. Yesterday I spent 5 hours trying to build the back chamber displacement that Jessie and my carpenter recommended me. I bought t...

The folks from lencoheaven.com have a thread where they as most of the people online stupidly damp pictures of different horns, supplementing them with howls “gorgeous” and “beautiful.” One of the installations picked my attention:

[quote user="martinshorn"]The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flavor and „heart“ but also 3 dimensional projection. [/quote]I need to say that that very muc...

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...

Paul SI don't have vinyl playback at the moment. My source is an MSB Platinum Data IV transport with transport power base, fed into a Metrum Hex dac. The amp is an Ars Sonum Filharmonia. So there isn't much of a power drain. Also: cabling is...

[quote user="tuga"]I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter... [...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not t...

Wojtek, Yes, too late. Once you've heard a good "stupid horn installation", there's no going back is there?
Yes, something similar to what was shown in Jeffery's GOTO installation. It should work the same on the floor or ceiling, (...
