[quote user="haralanov"] There is a huge difference in sound with hard and soft (sand based) walls even at 1mm excursion from the driver. [/quote]
If it so ten it is an interesting found. As I understand it is about the “stopping wal...

Although all of it has no relation to digital crossovers but still:
[quote user="cv"] On a vaguely related note: I dunno if you realise this, but conventional (ie excluding horn or large area ESL) speaker systems, even if measuring flat amplitude, i...

[quote user="Romy the Cat"] BTW, pay attention that TU-X1 while doing “space” does not change the size of imaging. Pay also attention how sensitively TU-X1 portrays the acoustic environment of each performing hall… BTW, if you use TU-X1 then try...

Mani, congratulations with Pacific.
You will not have problems to drive with balanced Pacific your single-ended amp. Juts buy a good quality XLR to RCA adapter or order XLR to RCA cable and you will be set. You do not even need to care about t...

The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). This is not to speak of its FR performance...
|
[quote user="Gregm"] No-one is criticising the ML3 (amplification) product. We are discussing the concept and the applicability of such products, i.e. the ultimate limitation of an amplifier called upon to work from DC to daylight and, accordingly, d...

My own playback is not operational from PurePower for now but last night I visited a local audio guy who run him playback from two new PurePower+ units (right and left channels) and one old PurePower (LF section). It was very fine sound, probably the...
|
Romy, I realize that you have a good deal more acoustic drive available than I do, but here is my experience, FWIW: I lived in a larger version of a very similar configuration for 13 years. My listening room was in "the same" spot as you pictur...
|
Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

[quote user="coops"]Romy just a quick post, after the Munich show I had the oppurtunity to spend a few hours listening to Ralph Krebs home system, the Cessaro Gamma's, super sound, the antithesis of almost everything I heard at the MOC, regards Keith...
|
Well, FWIW, my Audax LF units started life at ~100 dB and wound up closer to 96 dB to get ~40 Hz from them via ~ 4.75 cu. ft. BR boxes. Computer tuning was very close, only a strip of rubber weatherstripping in the vent opening between be...
|
The Lamm ML3 made me to think about this subject. Since my negative expectations about the ML3’s Class A2 operation turned out to be wrong and since we go into expense and efforts (totally unnecessary in my view as DSET make it worthless) and m...
|
Nah, not really I think I understood what you meant by real estate I just meant that I did not have large rooms, therefore not much space.I like your vertical array of horns and the line arrayed LF section. That doesn't take too much space. My pro...
|
[quote user="el`Ol"]Romy,<BR>what do you think will be the crossover points of the new system?[/quote]el`Ol,
I have no idea. I have no new system yet. If I decided to render the configuration with that battery boundary-loaded horn then i...
|
[quote user="jessie.dazzle"] Are you suggesting : 1) Running the upper bass horn from a second ML2 ? 2) Running the lower bass enclosures (sealed boxes) from a second ML2 ? 3) Running both the upper bass horn and lower bass enclosures (sealed boxes) ...
|
[quote user="Chirag"] Well..my first question would be regarding the application. The big Melq tube is already doing the bass towers...is it not enough current? [/quote]
Chirag, I’m not planning to use this power amp in my system. ...
|
Keep the driver stage, the 6N6P, as new as possible. This tube is very critical for the given amp. You might get a tube tester and measure the mutual conductance but with the low price of 6N6P I think it is hardly necessary. I would change it as ofte...

[quote user="Romy the Cat"] 1) I would like to try amorphous core foe my LF transformer. I know, I know, the amorphous core is not LF core but I know what I hear and if I found somebody who would be able to make for me d...

Sure, those, “events” around musical performance have HUGE affect to the musicians and I in fact LOVE to collect stories about them. What could be more “interesting” from a perspective of “anxiety” then for instance the Tanglewood performance of Shos...

Never heard it, but it has a separate LF section....
|
JJ, for me, the issue with Bruckner is that it does not often sound coherent to me, in terms of themes, phrasing, and structure. Rather, it often sound discursive to me. I have a copy of the 4th (comments in the Music section thread) that mostly make...
|
[quote user="drdna"] Now I have had the EdgarHorns in my system for a number of weeks and have been moving them around the room and moving things in the room around to make them sound their best. [/quote]
If you are not familiar with horns then it u...
|
[quote user="jessie.dazzle"] For a lot of reasons, I'd vote for an alternate placement. You've got that basement, so why not use it as a rear chamber? You might be able to use the volume "as is", without building a proper rear chamber. In this ca...

[quote user="serenechaos"] I do not know of importance of enemys death to this topic. [/quote]
Oh, this is a sheer pleasure but do not call that dirt enemy. He is not enemy but way beyond it, he is the person about whom I have a death-wish as ...
|
Interesting, Very interesting.
I might make some observations now, claming this recent modification as a success. The minor gain of sensitively certainly did not heart but the major advantage was defiantly the “activation of ceiling”. It is hard to ...

[quote user="rowuk"]Oleg has a lot of bad press in Germany for unkept promises and defaulting on delivery of product. Just keep an open mind next to the open ear. The best product only serves a purpose if it a) arrives and b) performs.I really like t...
|
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...
|
[quote user="serenechaos"] on 3) & 4): Dave Slagle, Intact Audio, knows a LOT more about transformers than I do, and the nickle autoformers I got from him work so well, I totally trust his (and/or Jeffrey Jackson's) judgment to over my "guess...
|
You will find a very basic motto or life theme here that keeps recurring:Random efforts produce random results!In relation to audio, this means that buying somebody elses best of everything does not lead to a personal superior result.Basically proces...
|
Actually it is very possible that it might be so. I made some rudimental measurements and concluded that RAAL tweeter and JBL midrange mounted in the same baffle has non-perfect time aliment. So, I will need to use gaskets under the drivers to time-a...
