DSP?!? But aren't there plenty of realtime options, from Marchand, etc? Hell, people are generally so excited about digital that they are pretty much giving away the analog boards.No doubt you've considered that the 2105s simply might not...

Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear...

Haralanov, let me know if you actually have something, otherwise I will continue with the Audaphon ribbon for the first round of the downward-pitching exercise. On the one hand, I wish I'd kept the Peerless 2" paper tweeters I had; on the other hand,...

Someone please jog my memory by naming some previous true Class A1 SE pentode amps, since I can't for the life of me recall any. This might actually work pretty well if targeted for LF! Adjustable "feedback" could help tons with Z matching, a very ...

Setting aside the small drivers for LF, while the rest of us have been all ga-ga about the vertical array, the pros have long since moved to the "horizotal array" for LF. Although I plan for several large drivers in large "modified IB" cabinets, I t...

[quote user="Romy the Cat"]Here is pretty much the idea that I had – a very tall line array with min footprint and with more of less corrected timing error by angling the front baffle. At the picture below the curvature of positioning of Macondo chan...

Well, it is a given that I am not a horn guy right now to begin with. Of course, the "theater speakers" were and are mostly dinosaurs and/or mostly of historical/nostalgic interest. I just want to mention some excepti...

Amir, I have a couple of options for swapping phase, at different points in my system. On 2 occasions when Clark visited me at my place, I could switch phase and he could hear it, every time. I was pretty impressed by this, though he insisted that it...

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, I'm enjoying this account of Melquiades upbringing. I must ask though: how are you sure that what you are hearing isn't on the recording? Not that I don't believe you, I just wonder if the stuff has been there all along and undis...

Not only ULF, and not only the usual "dead" audiophile drivers, and not just raw amp power. My experience suggests that direct radiator drivers from 10" diameter and under claimed "100 dB efficiency" (and - especially - in multiples) can benefit fro...

By the time I realized (last year) that I'd kissed off 2016 a year early, it was too late to edit/correct my mistake. Ironically, 2016 has been an "off year" for me, in terms of hi-fi, so, in fact, I've little to reprise for this year. I have poked ...

[quote user="rowuk"] If this is the best that your
engineers have to offer, you need better engineers. Bruce Edgar did far better
by himself without those engineers. [/quote] Rowuk, you raised two subjects that in my view worth to
cover.

Romy, if you have some spare diaphragm/VC assemblies for your S2 drivers, do the experiment I mentioned above (remove the outer layer of the VC) and we will talk about the inductance in terms of sound after you hear the results with your own ears... ...

I've been kicking around the Stupid and Lazy Version of this for some time, where one simply runs two different, "characteristic-[un]matched" drivers on the same frequency band. Oops... So, why not the same drivers pushed by the same amps that a...
|
|
Well, that is a much better way of explaining what I meant to mention, that it seems like one's best shot at character matching HE drivers (at home) involves accepting and starting with the lowest common denominator rather than turning up the power o...
|
|
Ric, that's pretty sophisticated stuff. I never tried hydraulic damping mounts, but I think the theoretical idea with the drivers is to keep them from moving at all, rather than using mounts that accept and convert energy in order to dissipate it.Sa...

Brad You are correct the model 19 does have the 802-g, but all of the 802 series drivers 802-b,c,d all outperform the 802-g. I have had everyone of them and have done real world tests with them with every type of horn and the plastic phase plug i...

[quote user="Joe Roberts"] I feel I am being objective when I say that a Mirrophonic system simply blows away Altec, Vitavox, TAD, etc. [/quote]
Joe, I am not a reader of your magazine and the phrase like “blows away” impress me very little. P...

Romy, I seem to remember J. Peter Moncrieff doing something like this a couple of decades ago, and he eventually "explained" it much as you have just done.I wonder if this approach is +/- doomed to a sort of "hazy" presentation, like the old Bose "bo...

[quote user="Romy the Cat"]Ric, I will not be using sand for decoupling. In fact I fill that sand is not good load bearing decoupler as I will have more or less point loading and sand will not work. I will be using sand for damping the horn surface, ...
|
|
Yes, that's just what I was referring to. In my case, it seems to happen just as the ribbon's own apparent contribution "vanishes".Another thing I noticed was that as this happens the mids also take on a more natural/realistic relatio...

Cybernetic phase blah blah blah...I (barely) managed to resist commenting about those pathetic little 4" drivers huffing away in that long narrow box, but I can't pass this one up!Just the buzz-words alone; it's got to be a translation thing!Too abso...
|
|
... and, be sure, I completely agree... ONLY trying to "cut the air" and giving some understatement to a someway heavy matter - wishing to avoid any hype, which sometimes helps when reality can't be properly explained... the thread is interesting and...

Brian,Microphone diaphrams, headphone diaphrams ,dome tweeters, all have to have the pattern applied with a technical pen i.e. Kohinoor or Mars. These are becomming a little difficult to find in all towns. A 50% mixture of Poly S and water should be ...

Well, I didn't come so close to answer your question right.I saw a few from the German DIY scenery and for them it was like the return of Jesus, best sound on PlanetBut probably they are still deaf as usual, because the Frequency step ups are limited...

Well, the Q5s were everywhere when I was trying to find big amps, and they really have no chance to move me. Even to do what they might do would take maybe 500W SS, yet Harley thinks he hears them at their best with the ML2.2. Then again, I suppose...

I tried a highly modded DEQX on my horns for some time, we did all the time alignment with it, we used 1st order and 4th order xovers and everything in between, we used LeCleach adjustment for bass and all the other drivers we had it sounding for som...

Petar, I might have just been tired, but I thought I saw a pair of "likely" 3.5" paper tweeters, and I played the hypnotized consumer and bought them, to start with my adaption education. It might be a while before they get here, but in the meantime...
