[quote user="jessie.dazzle"] To that I would only add the following: Start saving up now for a second pair of S2s.[/quote]
Yes and no. I used the second S2 for lower MF range but it is not only way to go. I would propose that any driver with large a...

Hi Romy,
It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) It would seem from all the activi...

Another particle of a good Horn Propaganda. It was published in Sound Practices in 1994 and written by Joe Roberts. I disagree with quite many of the author’s statements but his strategic view that the majority of the horns and the horn installations...

Any Google hits this site gets from my post is a gift from me to The Home of the Cat. Can't imagine anybody searching "Silbatone & Penderecki"..a rather odd combination of terms stemming out of a unique event.
Or how about "Silbatone &...

[quote user="Romy the Cat"]Joaco, thanks for sharing. You said that you use 2A3/45 amplifier, do you use choke or capacitance right after your rectifiers? It would be interesting if you plug a scope into your loaded regenerator and post a picture (ma...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

Thank you Romy and congratulations on your website, it just keeps getting better and better all the time.
The RCA1428 is a great sounding driver on RCA multi-cell horns. Not that I like multi-cell sound. I have never heard an original 1428 on a tra...

I would like to thank you for taking the time to give me a very satisfying answer and explain in detail your views on the whole subject and give a little more insight in to how you do things. Yes I suppose I really knew all along it was coming and w...

[quote user="Paul S"]Romy, no doubt the following derives wholly from my ignorance on the subject, but I have not been able to get away from a sense of "variable compression" with any compression horns I have tried. By "variable compression" I ...

hey romy and all-i recently came across a strange phenomenon (to me.. maybe not to everyone else!).I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of ...

[quote user="Romy the Cat"] I plug it for a first time today. It looks like it is sensitive like hell and I did not hear any titanium problems on it even without low pass filter. I do not have infrastructure now to look into it further. [/quote] I ...

That is the thing exactly, my upperbass solution has the same output amplitude as the compression drivers I am using, IMHO resistrors are the devil in xovers, they kill all sound. Now the difference between 109 db and 110 db can be overcome with c...

Years ago, the two different systems in which I heard RCA 1428s - in a fairly big warehouse and crammed into a basement listening room - used giant RCA multi-cell horns in combination with giant Ubangi bass bins, passive crossovers and vintage WE or ...

N-Set, the Tesla AROs make much better mid/upper bass than Altec/JBL, etc. The "factory"/"theater" boxes for these are HUGE, with double walls, basically IBs, but they can indeed "pound" from a smaller enclosure, or even OB. I hoped Fikus would eit...

Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b multicellular horn that sh...

[quote user="KLegind"]I had a look at the pic of your speaker just now - may I ask about the reasoning that went in to choosing a diffraction type horn?Also, your midrange looks like an open baffle type. What kind of back wave/diffraction management ...

Back in 2019 I was converting the Altec Model 19 into myCetla 91 version
by introducing to it a custom new 18-section horn loading by Vitavox S2 driver.
It was a fan project and it was using in my Opera room for years. This morning
I was passing b...

[quote user="dazzdax"] Sakuma's idiosyncratic and esoteric way of thinking (he believes for example that tubes have a "soul") is not to everyone's liking. He is projecting his mind into a sort of tone control. At least for him this tone control bring...

[quote user="Paul S"]Murat, that's a lot to ask from one driver. [/quote]1000-12 000 is 3.5 octaves.300-3000 is a bit less.[quote]In any case, if you do get useful results with the paper driver, you will have to turn right around and integrate it bac...

I was reading
a few days back Altec audio forum that had a thread “GoodSoundClub owned by an
idiot”. In the thread a bunch of “confident about themselves” audio folks discussed
what kind crazy idiot I am and what might be underlying reasons for my...

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...

... or wondering if it has any new insight into horn design.I did not read the book but I find funny that person who presumably do not “believe” in horn write a review about the presumably horn related book. It would be similar to ask a blind person ...

[quote user="hagtech"]Interesting. I'm wondering here if this is the key to eliminating the honkiness I hear in most horn installations. From your experiments, it seems that the low frequency extension is key. Push it too far and it...

There is a guy named Ad in Netherland who makes looks like aluminums (but I am not sure) horns for 1.5 inch compression drivers. The first picture it looks like an exponential: W=39cm/15.4Inch. L=45cm/17.7Inch.
I do not know if Tractrix and the Fren...

I agree Steverino, IMHO Bass in the most tricky part of audio!
A couple of things I found out that help. Most importantly, Time Alignment! Not just between the channels crossing right to the next frequencies, but the whole system should be time alig...

[quote user="Jorge"]I am not using the S2 driver, I have been going the long way testing a bunch of different compression drivers. Right now I am testing the TAD 2001, I can say leaving it full range going all the way up, it develops a certain ...

fair enough- you're absolutely right, i didn't!it's difficult to get that perspective on sonics without legitimate guideposts-- even with a lifetime of playing and recording music, it's difficult to know what the parameters of recorded sound ar...
