Romy, thank you very much for very detailed explanation of your horn theory.Let me present some doubts about it. From physics basics when we have more than one springs (suspension, throat resistance, back chamber) we can consider it as one spring. Th...

It's too long ago for me to remember the sound of your system, but not too long to remember my reaction to your playback. I remember the bass being different. The adjectives that come to mind are only words, but for the benefit of readers who may n...

Romy's quotes in blue :"...Discussing the Jessie project we multiple times mention the idea of the large midbass horn hanging above MF section... The rational was to have it positionally contra-react the output of the upperbass horn... But do we au...

I laid my hands on WinISD speaker modeling tool, which seems to be quite popular and widely used. It can model passive radiators too.
Here are the simulations of my idea of the Dannoy bass: Scan Speak active + Scan Speak passive in the same bo...

This post is the phono-relevant part of info carried over from my recent "better tubes" post in the ML2 thread.Subsequent listening has established that the electricity during that session was better than I'd thought at the time (dammit!). ...

Gentlemen:I assure you, Infinite Baffle bass simply has no peer. Yes, you do need specialized drivers. The Infinite baffle bass concept is so old, it's rarely even considered anymore, plus, you are indeed married to the installation....

I think we have to subdivide bass into upper bass from 100hz to whatever your midrange does and bass under 100hz and then maybe infrabass.
Front loaded upper bass horns are fantastic and I would say if you never heard one, you really nev...

I've managed to make my own room treatments thus far, all bass oriented and although some broadband absorption has been used the bulk is effective 30hz - 500hz. It is an architectural type of solution where I have a covered the front and side walls...

Duke, you see, the lowering of output impedance is great but once again “how it was used”. When we hear the result do we hear the effect of a more infinite dumping or we hear the problem that coming with application of feedbacks, or we hear the probl...

Well, that is a small room, all right. Regardless, a "mid-bass deficiency" alone could literally evicerate big works. I have written up the Kubelik/BPO/Dvorak 9, because I think so highly of that performance. It should absoutely be loaded to the g...

Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use your upper bass horn to p...

Since my left channel along with midbass horn is more or less configured I made today a first rest of the full assembly - with LF section. The midbass does somewhere hear 40Hz and I set the LF section for 34Hz, drove it from B2 via the SMS crossover....

Gday I am building a horn system. Ihave 2 sets of plans .http://www.volvotreter.de/downloads/150Hz_Midbass_Tractrix_Horn_v1.3a.pdf this one is a 150http://www.geocities.jp/arai401204/Download_Page/Download.html and this one is the first in this page ...

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...

Rakesh,
Yes, life is too short but the definition of belter ULF channel is not something that one might learn during "a project next coming weekend". The most important in audio is a state of realization and obtaining this state is a matter of...

Zanon, at this point I do not think about specific of amplification. I more care about the transducer per location ratio and a filtration in context of it in order to get the “filling schema” of the room properly. The quality of the powerful amp will...

Bass arrays are considered infinite when they cover min. 70% of the room height. It is also important that they are mirrored (ceiling perpendicular to the array). Your new room is not ideal for bass arrays.I don't know whether you have read this pape...

Haralanov,
Here some raw cements of my on it, without any particular order of importance….
1) Sand damping it beautiful, it is well-recognized, but you do pay cost for it, in your case the cost is space. Sand is very little compressibl...

Mani,
I would leave the subject of DSET/horn setup for another thread and would drop a few words about Zu Druids. They are not the speakers that I would ordinary comment but since I have a local guy with Zu Druids and I had a chance to hear th...

Here is another one, quite serious... only this one is 109 dB efficient.http://www.danleysoundlabs.com/pdf/TH%20221%20spec%20sheet.pdfThink about this for a minute...Sure, those motors will still need some current, but you might be able to rev 'em up...

Unicon, yes, this subject will be very much continue when I am ready and have some actual data in my head. The good news is that I learn that ASC goes custom work, I did not know it. I just afraid that ASC is a large company and they would make me to...

I seem to remember that we've covered somewhere the sonic benefits of SET at lower frequencies, but I guess I never really thought of ULF as "bass", per se. If someone ever comes up with an SET that can be an effective part of an AuraSound circuit, ...

A friend of my after reading my comments about the EdgarHorn installation in Vegas (in here) asked me why do I think the bass in Bruce’s room behave as it behaved. I tried to think about it. Some of those thoughts intersect with some other projects t...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

[quote user="skushino"]Romy, please elaborate on your experience using a 2nd order crossover. What do you mean "rules of the game change completely?" Why did you try the 2nd order? Are you concerned with damage to the driv...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...

I pretty sure we are talking the same things, ie
Phase shift = frequency dependent delay - spreads a signal out
Geometric arrival delay is linear phase - delays all frequencies equally (obviously)
I was just hypothesizing that a slightly ge...

It is likely that getting any giant LF horn to contribute musically as part of a system will require a number of iterations, so it would be good to allow for this initially, somehow, to be at all realistic or practical. With...
