Once again, let make it the last post off the subject of the 5-chals Milq.
I think it make sence to start from 370Hz-400Hz horns for S2, targeting it for 1000Hz. Then the lower bass horn, for instance the 45Hz, however it should have a chamber of m...

Hi Dominic,
I have some Rola's. Although intended (in organs etc) for quite widerange use I'm not sure that for listening to music they should be allowed to go too high. The other thing I found was that what lower frequencies they produced were more...

The $3.6K per pair, if they are good divers - the 2440 level, is a tolerable price for custom-made drivers. I presume that he does not include and PS into the price. My major question would not be about the drivers – the filed-coils are very simple d...

[quote user="jessie.dazzle"] Is the S3 as sensitive as the S2? [/quote]
Yes, they are appearing to be the same sensitively.

John, I am bit puzzled with your response. I do not know what would be a proper material for cone/dome of diaphragm. The source where “tone” is born in compression drivers is absolute mystery to me and I in my holly naiveté believe that no one else k...

So, I guess you do not measure flux if are getting. You might measure sensitivity and we might presume what when perm magnets has the same sensitivity as electromagnets then the drivers have the same magnetic flux density. Let also presume that when ...

Msaudio, I also had all 1” Altec drivers and learned that what Altec does in those drivers it very good to sound reinforce Sarah Palin speeches during in her Midwest redneck rallies but they are hardly acceptable for serious music reproduction. Brad ...

CV,All that you point to is quite correct. My comments were based strictly upon which coil voltage would be a superior sounding electromagnet. The only benefit I can see to a higher voltage is the faster rise time in the voice coil of the induced EM...

I am currently planning high-WAF speakers for my sister which have to stand in the corners on the floor. Asking for small corner horns I was told the EV Baronet could be a solution. Simulating it with roughly estimated dimensions I found that the FR ...

Nice site, Romy! Space is the Bomb!Regarding the remodel, it would be easier to speculate if we had some photographs of the areas we are discussing.At this point, speaking abstractly, it looks do-able, even if those rafters are trusses that had to b...

Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that a niche-manufacturer such as W. ...

"Architectual" (man-made) joists have some decided advantages over natural lumber, including excellent unit-to-unit consistency. Most residential "TJI" joists (as opposed to beams) are made straight and installed without an initial "crown" (manu...

I have been using my Ekornes Manhattan chair and generally I am pleased with it. It is a bit not deep enough for the taste of my ass but with footstool it works fine. There is however an aspect in all of it that I do not likeand that I did not think ...

[quote user="Romy the Cat"]So, if the Ultimate MF Compression Driver is used from 1000-1500Hz then why shall it be able to play 500Hz? The answer is: he harmonic reserve – the driver that will be suited for 500Hz will have larger cone and softer sust...

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...

Yes, Paul, you are right that it has to be pointed that the frequency extension, by itself, does not guarantee anything (but that’s why I posted the thread in Audio For Dummies section :-) ). OK, now let’s see how the tweeters should be used (in cont...

Nice work; bravo Mike! With regard to improvements to the S2: Apparently Romy's prayer, one of them anyway, has been heard and would seem to have been answered; a diaphragm-centering guide has at last been added. As for the rest (other improveme...

Hi alex. Sure the 12 incher starts narrowing around 700. But the horn does too. And in that area you cross both at -6dB. which contributes to narrowing vertically. The magic is, to merge in a way that off axis its not getting too odd in a complex sum...

Something they mustve obviously done better than others using beryllium. Judging the sound. In a positive way. The lower 3 are titanium, but all upper 3 are 4/3/2 inch BE sourced from truextend. The suspensenion however is soft and allows excursion.I...

One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.
Me and a friend ...

Ok, none it is time to dive into the practical process of tweeters alignment. Once again I presume that we are taking about monopole tweeters that use AFTER your midranges compression drivers (read my previous post). Some people use term “supertweete...

A mix of conctrete and steel skeleton is a very good mixture, particularly for the upperbass horn. BTW, go not be “disappointed” that you did not go for Tractrix. The Tractrix has many advantages but for the range where you operate I hardly see any a...

Dear Romy,OK, some more about the midbass.Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than w...

Thinking about my Vitavox S2 “fundamentals channel” I can’t stop think about my hypostatic view about the horns. Year after year I was mucking what GOTO does when they introduces a horn for a couple octaves. Ironical now I am truing to do the same fo...
