The recent events in my playback made me to think about he new prospective duty of tweeters. Since the Super Melquiades was enlisted for duty the Vitavox S2 got it’s own dedicated amplifier channel and stopped to “see” the coil of upper bass driver. ...

OK, I guess I am a little confused about how you get * enough * acceptable tweeter-less sound above 10k Hz that you can wait to cross over at 13k Hz. I don't know the Vitavox S2. Are you saying the S2 goes strong, clean and...

Hi romy, mine are the 515-G drivers. I will be x-ing over at 600hz to Vitavox S2's (2nd order, yipes!). The S2s are in 320hz LeCleach horns. I was kind of hoping for just a general reply like when you guys look at a pictu...

[quote user="guy sergeant"]Not yet. I'll give him a call & put details of the reply here.[/quote]Guy, when you will be taking with Mike then here are some taking points for you if you wish:
1) What type of magnet Mike is planning to use in his new...

A few questions. What driver is it? It looks like it is 15 Vitavox, is it 151 or 15/40? What the resonant frequency of the horn and driver with no back chamber? The most important: how the hell all of it sound. I do not be believed that you did not h...

Hi Romy,I knew that would be your response! It's definitely a case of (1) or (2) though. If he had been upfront about them being new, and not that he found them in a cinema, that would have been another matter. Also, I believe Mike Harvey owns the ri...

For all S2 fans... please be aware that seller "milesvintage2007" was claiming to have found a load of diaphragms in an old cinema (yeah, lots of those running Vitavox in Hong Kong, I'm sure...*)Even forged the labels on the tins... He has since remo...

I would start with the freq from 60 hz to 10 khz. If you already decided to use the Vitavox S2 and AK-151 get those and start using them in that range, it will take a long time to get them perfectly settled. Will you use the AK-151 inside a b...
|

Well, the tunnels will certainly affect the sound, whether they're inside or out, whether or not it winds up mattering to you, and it looks from the photo like the Vitavox will be in the same situation as the Tannoy. You did not say if you aimed to m...

I have two pair of the old 15" Vitavox: two drivers coned as K15/40 and two as another less common variant with a softer suspension and lower Fs but I cannot remember right now the name. Shortly, a brand new pair of K15/40 shall arrive along with ...

"Best bass" is of course a matter of opinion based on experience and expectations. The (original) Hartsfield LF driver is certainly "designed for horn loading", like the Vitavox AK-151, whereas the AK-150 and the JBL D-130 are designed to be direct r...

So I am aasuming that you are referring the very low level capability of your driver or amps? The subtle nuances?What other drivers did you find did well beside the Vitavox. I always felt that most comperssion drivers are a little tightand need to...

I was thinking, Bill, that you now have S3s running down to 400 Hz. If you ever said what you are using below the S3s now, I don't remember. I have only heard the 15" Vitavox a couple of times, many years ago, but I did once own Altec Lansing 515Bs, ...

Romy,Just one last note here, since many folks will start here. Having finally finished reading your enourmous work on the Vitavox drivers I would NOT reccomend using this process on them. It would be so very difficult to arrive at the corr...

R,More interesting observations there. Your Lowther thoughts are similar to mine - I always wondered what a lower flux version would sound like, but non-horn loaded and whizzerless a la Horning. Even got round to obtaining some magnet-less motor...

Listening the argument of the field-coil’s people I note that they constantly stress the demagnetization subject of the driver’s magnet, advocating that with electromagnet “the field coil will always produce the same strength now and 100 years in the...

No, I've not built the big woofer towers yet, but have some steel here to make the first few Cannons up to try out and measure and listen to to see if I can make the system work. It is essentially the same solution that Romy uses so I think I should...

Absolutely true; I end up breaking and rebuilding the mold (actually an internal plug) for each half of the 40Hz horns I'm currently making. Ironically, the resulting horn ends up looking like a mold.For the 115Hz horn, I managed to coax two complete...

Romy,I am very interested in this thread as I have heard the latest version of the speaker "eufrodite mk IV" . I do not think any of your objections would be changed by the latest version as he is now using push-pull array of beyma 8" drivers up to 2...

You have said that you want to keep the channel relatively small, and sealed is one way to do it. I don't know your Vitavox, but a larger ("IB") box might have more of the dynamic transcience you mention, and it probably would not be a step back in ...

I would like to pass some summarizing observations and some generalizations regarding the entire “Water Drop” project.
THE IDEA
The idea of trying to find a tweeter to compliment Macondo was a good idea. Many of you know that I was proudly declari...

I think 8-8-1 will be very good configuration all together.
Make sure it stays sufficiently far from back wall. Point the axis toward to your shoulder and I think it would
be fine setting. Turn off tweeters and Fundamentals channel and set right
b...

I tried the driver and generally I do like it’s sound a lot. It more sophisticated then Linaeum, it is more noble tonally and alike the Linaeum is seamlessly melts with Vitavox S2. In fact I am developing recently a theorem according to which a compr...

Oops,
I'll send the images again once back at work on Monday.
The thraot size will be 7 inches.
Yes I have thought about paying someone else to do the work, but that sort of skilled labor is super expensive around here.
And... Yesterday ...

It is very uncommon, practically never happens but still very rarely it is possible to talk about sound or playback systems from a prospective of “absolute tone”. Yes, the audio people love to take about tone of their audio but in 99.999% those audio...

de Charlus, this “are not afraid of cabinet resonance per se” is complicated subject. I have raised the topic in the “How to USE “Resonating Oops” in loudspeakers” thread:

Wow, where did you see a 1kW
amplifier that is able to produce bass that does not make you vomit? Also, why
would you need power like this. If you go with 15” high sensitivity driver,
then you would need 20-30W max. Do not forget that your objecti...
