Hi Romy,I understand the need to determine if the upper knee of channel A sounds better, or the lower knee of channel B sounds better, to cover a given range.However, I'm contemplating having a 1.4" 250Hz Edgarhorn built and am curious if you determi...

Hi Romy,I do not know how much experimenting you have done running a compression driver with no LP filter through your 250Hz tractrix. However, in consideration of a given driver employed, irrespective of adjacent channels and by your various criteri...

Hello Jeffrey,BUILDING UPON the inherent/latent Lloyd Wright-esque and Frank Gehry-esque aesthetic potentiality of your midbass horn design, and visually integrating the total horn package as a system within these aesthetic schools (or derivatives th...

Hi s e r e n e c h a o s,Ok, now I see from the 6moons VSAC photos how the woofer was loaded...I was 'worried' Jeffrey sliced his woofer into two equal halves and then placed a 'dividing board' straight through the woofer (as in midbass horns '...

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...

What I seek to know is: how did the midbass woofer Thiele-Small parameters change by cutting them in half to fit into the half-moon throats..?I'm Horrified nobody has brought this up yet!!http://www.youtube.com/watch?v=NzJ7Km1tXKI&feature=related...

Hi Romy,Interesting direction. Sounds like minimalism (though not necessarily in the typical musical sense, e.g., John Cage).http://en.wikipedia.org/wiki/MinimalismNeilPS: Please excuse my being way under the 165 word 'minimum'....

Hi Skushino,1) In your post above regarding certain(?) of Bruce's products, can you please identify *what* crossover parts you received or heard (in context of given system) which you feel are "low quality" ..?2) Which model & ...

Thanks Romy,Yes, I received your advice in the past privately regarding proper size for 1808 enclosure, and I thank you for pointing me in right directions. Yes, sealed box is simple calculation using e.g., WinISD. I am experimenting with&n...

Hi Romy,
I'm not sure if you're looking for a seperate 'mini system' amplifier, but you might want to look at the handsome little T-amps from www.audiomagus.com

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...

"Do not use plastic caps ... but go for a tandem of electrolytics Nichicons with active biasing."
Hi Romy,
Please excuse my ignorance. Can you please clarify what you mean by "active biasing" -- in relation to the caps?
I'm thinking to get...

Hi Romy,
Since you have certain opinions on TAD/Beryllium sound, Im curious:
1) Which TAD drivers you evaluated (2001, 2002, 4001, 4002, 4003) ?
2) With what Fc horns?
3) With what horn materials?
4) With what Xovers?
Thanks!

Hi Romy, If you scroll down to the bottom of the page, there are 3 units supplied by Fostex: http://www.madisound.com/cgi-bin/index.cgi?cart_id=1455929.29661&pid=315 Neil...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

Hi Guys,An idea I've had for damping thinner horns in a more or less aesthetically pleasing manner is to house the horn in a Sonotube rigid cardboard cylindrical concrete former, and then apply the desired damping material inside the Sonotube.&n...

...Or plug all but the desired LF exit path? This might not have the same compression ratio a stock though. Well, I am still learning about how phase plugs operate.Neil...

By "flat ended", I assume you mean how the mouths of his current 650Hz and older 300Hz horns have flat edges, rather than even more gently rounded ones?
From memeory and a photo, Bruce's current 350Hz appears to be 'slightly' more rounded at the fro...

Hi Romy,
FYI: The previous photo of some unknown persons "pile o' horns" appears to be:
Upper midrange: 1" TAD TD-2002 mounted to 650Hz Edgarhorn
Supertweeter: Fostex T90A or T925A.
Lower midrange: ...
