Romy,I took your advice and now have a single 2440 driver. At least i THINK its a 2440. On opening it i find that it has a phenolic diaphragm! Have I been sold something else? I was not aware that there were ever any phenolics for the 2440 family. Wa...

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

Decoud, in order to say anything useful I would like to know to the following: 1) Where the tweeter will be installed? 2) What the size of the room? 3) What are you planning to install the speaker in your room? 4) What LF solution do you consider...

Romy, may be the alnico jbl 2482 + aluminium diaphragm (plastic surround) would suit for your application here. I tested such driver on 200 hz tractrix horn and worked fine. Went down well under 200 hz and is 2" throat. It is heavy but I would be usi...
|
|
Kris, I agree with you about the unobtainable 300Hz.Had really hoped for that, but so far no go with my set up:An old Oris-150 with a 4" throat wood adapter/cradle that John Sheerin made for me,with the 2482 playing out the back, so you see the entir...

[quote user="haralanov"] Congratulations you have found and use this principle, otherwise the back chamber acts like pneumatic brake for the lower working range of the diaphragm! [/quote] Actually it shall act as “pneumatic brake” in a compression dr...

|
This is probably the reason I can listen to EV Patrician IV in relatively small space and close to the speaker without much of fatigue. The other factor must be that it's 4- way design with narrow band-pass for each horn. EV T25 2" phenolic com...

I think I like what it adds to 8-14k range also, so If I use higher order may be I'll miss it...but I'll try if you suggest.I would like to ask a question regarding 400-1200 range (fundamental channel). You are using Vitavox S2 for this range. Is it ...

|
MS2, I don't care much about compression drivers, but I have spent the past 2 1/2 years playing with direct drivers, trying to figure out what makes good sound. And no matter any notions about "scientific discoveries", the whole process has been the...

What the sonic impact will be? I clearly have no idea. I was slightly desponded and warned that my excremental S2 with electromagnet did not have the “sonic impact” that I find useful.Regardong the Quartopuss... Chris, you're confused because t...

... 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="jessie.dazzle"] The AK150 and 152 are not new creations dreamed up by Mike; they were made back in the day by Vitavox but nobody ever talks about them and I have never seen either. See the Unofficial Vitavox web site; AK150 = Catalog...

[quote user="cv"]AlloI had a theory that the bug screen was helping to damp horn modes/refelctions caused by a mismatch between the S2 internal flare and the horn flare rate. I have 340Hz flare JMLC horns, which may be expected to give less of a mism...

(1)Interesting that you omitted in your response the “insultingly-extended HF”. I feel it one of the biggest problems as luck of “transients from distance” people foolishly substrates with a presents of bogusly-supplement...

[quote user="cv"]Romy,Are you currently implementing "nominal" 3200Hz x/o on the mid range channel S2 using a cap at the driver? I know this works nicely to ameliorate the "secondary" resonance of the plastic edged diaphragm.Reason I ask is because t...

Petar, you know my set-up well, and your remarks are correct within the context of that knowledge. However, despite the obvious technical problems, Etta's voice - per se - is actually - remarkably - accurate, with plenty of body and soul. While I s...

So, I did exactly how I described in the previous post and I returned back to the plastic suspension diaphragm sitting in the “new” drivers. I lost ~3dB sensitively and was forced to go back to 3uf crossover, exactly how I described in the beginning ...

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...

I love not only the beautiful results you are getting, Jessie, but also appreciate that the methods you are adopting allow you to continue to refine your horns on the fly. Particularly nice, to my way of thinking, is that you can tune your horn...

Romy,
I am off to Taiwan tomorrow but will ask the question by email. I have not heard that kind of custom diaphragm ever available from GOTO on SG146LD4 driver. I know the 15" woofer can be request with different stiffness of the cone.&...

The played today a little with Vitavox S2 driver with electromagnet and made some measurements. Measuring the relative magnetic force (I use Hirst GM04) I found out that increase current up to 3A linearly increases the magnetic force in the gap...

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...

Hi Romy:as I don't consider the thread as emptied, yet, I'd wish to add some thoughts after more days of listening to my system.I re-read an half-page chapter in French from Jean Hiraga's "Les Hautparleur" essay, concerning time-alignement and p...
