Maybe not exactly what your striving for, but there is a kit that Danley SL sells called the DTS-10 that supposedly has a lower knee of 11hz. Its down a bit at that frequency but given some room gain still very useable output down low. ...
|

Yes, it is a standard SH-50 run as Danley suggests. I have little experience of traditional horns beyond a macondoesque 3-way tractrix stack I created so as to get a feel for horn sound. I'll drop you a line about the melq builder....

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

I remember reading about a turbine subwoofer 15 years ago called the Phoenix Gold Cyclone or Typhoon. That was for kids in cars.Tom Danley the inventor had some comments:http://www.diyaudio.com/forums/subwoofers/55122-pg-cyclone-non-cone-subdriver.ht...

This is a synergy horn, a topology that Danley has a patent on, I believe, and certainly the most expertise. There have been extensive discussions on this site about it, including Romy's theoretical objections to the idea. In a synergy configuration ...

But efficient (in terms of space usage) and radical.put woofers in the sides of flare of your attic horns, sort of like Danley Synergy horn, not near the throat but towards the mouth area, using the attic as the infinite baffle.But will the pressuriz...

There is a thread about unity horns featuring Tom Danley himself on diyaudio.com.http://www.diyaudio.com/forums/multi-way/195955-unity-horn-budget-drivers-active-x-over.htmlImpossible that his speakers can be good, as he uses BMS drivers ;)...

Danley, however narrow his focus, is intelligently inventive. It is hard not to wonder what he would do if he had a refined ear to hand, so to speak....

Here are some real world measurements made at the 2007 NYC sub shoot out. The distortion numbers and characteristics should help us understand the difference between tapped horn distortion and conventional front loaded horn distortion.
The fir...

I suspect that the 8" and 5" cones and 1" compression driver are in the Danley Signature Synergy multiple entry horn. This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an ...
|
|
John, I have to confess that I feel very not easy about the idea of Synergy horn. I did not hear the Danley Synergy horns and I have very superficial understanding of what he is trying to do with the whole Synergy/Unity idea. The whole idea does ...

MoreartDouble-driver "back horns"? I am not sure what you are asking about, or what exactly you are promoting, but I do not agree with lightweight, square-section horns, because I have never heard one that worked, apart from shifting certain frequen...

With all my respect to Tom Danley to release a loudspeaker
with onboard DSP and to claim the “highest quality of home audio in the
industry” is kind of ridiculous. The people who know about digital as much as Tom
Danley knows about loudspeaker fee...

Thanks, Josh. I looked for it and found a good link that accumulates a lot of recourses about Danley DTS-10.

I did not know about DTS-10 but this morning I did sent to Tom a...

No, I have not pushed it hard at all: I am just trying to understand it in the mean before I look at the extremes. Though 100db sensitive, the SH50 is designed to handle 1000W or some such absurd power, so it is surprising that it works so well. It i...
|
|
Josh, I never tried exactly what you are describing, and I don't understand how it would "cancel errors" in real life, but you should try it. For a similar-but- opposite take, have you seen the Danley multi-driver horns yet? There's more on these -...

Romy, apologies for being unclear: the amp is not yet built: this is just a spare chassis I am offering for others who may wish to build it too. Inputs and outputs have not yet been added to the chassis. I therefore cannot comment on the sound yet bu...

I have to admit that Tom Danley is one of a handful of audio Svengalis that hypnotize me. This effort appears to be aimed at home audio, for a change, complete with built-in amps, more or less plug and play. This speaker will likely perform to PA spe...

The Danley idea - or something quite like it - does look good for LF, but maybe less good for MF and up, I think.Which takes me back to the whole "point" of the imaginary "single driver"...Effing around with mix-n-match "systems" back in the day...

Sure, I speak of amplification here because that is what we are talking about, but naturally playback is playback, not any of its elements taken alone.I am not sure more detail about the entire system is helpful because no amount of detail is really ...

I think we are all agreed that if time alignment and space were not issues, a bass horn would be the way to go.Now, I'm fairly convinced that the overwhelming benefit of horns in this range is the phase response, ie flat group delay vs frequency. Mos...
|

One thing to bear in mind with the bass horn delay - I thank Tom Danley for explaining all this a while ago - if I understand it right, a small direct radiator (ie small in relation to the wavelength - which will obviously be the case with ...
|
|
ahh yes, tapped horn is what you would call "close bottom." It has to be designed around frequency response (which is very narrow band). It isn't a problem getting one to go low enough though, and the quality of sub bass produced, smooth yet dy...

[quote user="decoud"]For what it is worth, unless you are irradiating a concert hall, the SH50 is perfectly adequately driven by a 15W single 845-based SET, and I will shortly find out what it sounds like with a full range Melq. [/quote]Probably 15W ...

There is site out dedicated it infinite baffles subwoofers. I am not sure how serious they are as they use mostly metal in rubber drivers as got thrilled when “Apollo 13 takeoff, my doors move back and forth 1/2", and the frequency is below 5 hz...

I am NOT talking about single wideband drivers or any back loaded type horns. I am talking about properly made front loaded horns.
For example, the Danley Synergy horns, that use single horn with multiple drivers to cover a wide band...
