Here are a couple of measurements of S2's (not taken at the show).Both are taken at the listening chair, ear position in my system.This one is on a 2nd order passive, spec'd to cross at 1.25KHz.(This was Coco's S2 with new surrounds on a Le Cleach 55...

I have also designed my bass horn to operate between 160hz and 600hz and it will use a supravox 285-2000. It is a 110hz cutoff tractrix horn. However I found out that, there is a modified version of this driver that suits my purposes better. It is by...

I have to admit I have no idea and did not experiment with matching horn loaded tweeter to big ,direct radiating "extended range' MF channel. I'm not sure it's doable. I was speculating on the reasons why the owner of Moscow instalation switched from...

Hi Romy. Confused by your statement i flipped a few pages back and just noticed you changed / corrected your opinion along the course. So you're back to white polyester? I have 6 different dia's in my storage, all different surrounds, but did not ...

I would like to post it into this thread, as somebody who cares about S2 should know what I ended up.
Anyhow, now it is officially: I permanently removed a tweeter from Macondo. The properly voiced S2 driver (with a transparent enough track- h...

You have identified the tricky parts -the transistion between the front and back horn as well as the throat of the front tractrix horn. A one to one throat with the front horn works best with my coaxials and a short 1.25" straight 'ring' ...

For now I'm quite sure about one very important channel - 1200Hz+.
JBL2453 in 550Hz LeClech horn works perfectly for me!
For the lower channel 500-1200Hz I've tried the same driver JBL2453 in 350Hz Tractrix and result is not bad, but not pe...

...this interesting point has no practical answer. First of all in the case of Rakesh horn what N-Set proposed is not necessary. Those 115Hz Hasqiun-style horns that Rakesh emulates are well dumped with own mass and own ...

Hi Romy,Got my new Le Cleach tractrix horns (320hz) for the Vitavox S2's. I'm x-ing over at 600hz with 2nd order 12db/Octave which I know is barbaric for you but it is all I have for the moment. With the new horns the S2s are puttin...

Phil, as I can see most of your horns, if not all of them, in one or other way explore the baby-cheek idea. Are any specific reasons why you employ the baby-cheek so heavily? I know the basic theory about the baby-cheek radiation pattern (something t...

Hello to all Good Sound Club Members, and special thanks to Romy The Cat.
We are a Polish audio company started in 2011.
For now we have two tractrix horns available - 400 Hz and 600 Hz. Next week we also should have 115 ...

Romy dropped by yesterday. He goddamn demonstrated how "yellow" and compressed the Lowther (Reps-1, in my case) is, using my system, by simply playing other channels and the Lowther channal separately (mine is a 4way multi-amp set up, so it's v...

hello kids, a few weeks ago i started my hunt for a pair of speakers....i've been attached to my big system with a pair of headphones for the past year and feel its time to get some speakers to listen to music with (plus, i think my ears are now...

Hi Pete,You have a similar size room to me. I'd rather like a large 4 or 5 way setup but don't have the space. I use the S2's (in barbaric stylee) in damped RH330's. Beneath them I use a frontloaded (folded) bass horn Vitavox made called the Oracle. ...
|
...if you want to use it "pure" as it were, without any in-between equalising. Or you could tailor the amp accordingly. I would see a lowther working well mid-high rather than mid-bass.My experience is limited, however, to EX-4 used with wizzer in a ...

Ah yes, sorry - that wasn't remotely clear. The drivers I have played with briefly are S2 and field coil RCAs, both have the same 1.5" throat. I was referring to my initial impressions of the sound on Martin Seddon's 160Hz horn (T=0.8 JMLC). Previous...
|
"I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver." Is this also why you use tractrix curve for expansion? To shorte...

[quote user="jessie.dazzle"]It is interesting to note that the evaluation tool shows lines radiating perpendicular to the curve at any given point, just as the sound wave is supposed to be oriented as it progresses along the horns length. [/quot...

Collin,
I do not remember that I wrote that Trios are “duller”. In fact I do not remember I ever wrote anything about Trios in comparing to my current hors. Furthermore, my “Macondo” derived for the Trios and practically fully inherited the Trio’s ...

[quote user="Romy the Cat"] The tweeter is sitting at 1.5K, first order. That is king of low crossover point for tweeter but it is OK. The problem that I see that with this time of the filter and a compression driver used I think the horn for th...

[quote user="NBC"]… what do you feel is the upper usable frequency limit for operating your 250Hz tractrix before any negative effects of the horn itself become evident and begin unacceptably compromising the sound…[/quote]

Very, nice thanks, ulf.
I never heard this company and it is good the more horny newcomers pop up her and there. The epoxy carbon-kevlar and glass fibers staffed with damping? I wonder how more fun would be if they staff these hollow horns with sand...
