How Wilson sounds:Pressure caused by non-linear bass squeezed through narrow port holes.Shining caused by the papery upper mids of a too high crossed 6.5" midwoofer.Sparkle caused by the metal ringing of a titanium tweeter.What Wilson does:Use st...

Played around with beethoven 5th and guitar placement. I do not understand what to make of my experiment. I do not notice difference to upper bass but in the mass strings higher up, there are less holes in the sound if i may, more of a cluster of ins...

So, you use DCX 2496 for deals but not for crossovering and your crossovers are still on analog domain, right? Romy, I do everything in the digital domain so I use DCX 2496 as my crossover as well (but analog SS pro amps). I know you're no big fan of...

Fi-analy started listening the FR combo! The setup is somewhat haphazard:* P2S unknown - trying to get 231.5mm recommended by the Germans, took the pains and the cost to design and make a special collar but missing a laser engraved protractor to see ...

Wow, it is worth to live in Boston and have a day of miserable rain.
I really like what I was getting with CD and I have a few very interesting results coming that should be even more exiting, at least one of them is more defiantly is very exciting ...

Marc Henry-In the 6moons write-up, you mentioned the Altec 515 re-issue not being satisfactory for your purposes on the Grande Castine horn. I presume the specific 515 variant you used was the 'g' type (designed for horn loading) rather than 515'b' ...

[quote user="oxric"] Firstly, the costs involved and the real chance that this project might not work make this project statistically a horrible waste of money, time and resources which could be better spent in pursuing other solutions which are ...

[quote user="skushino"] I think you are saying the effects of my room may be dominating any problems with the Edgarhorn bass, or at least I can't know since I don't have any objective data. Is this correct?
Maybe you're right. But here is wh...

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]
I do not think I called you with names...

user="anthony"] I have noticed that there are several commercial horn
offerings that push a wide bandwidth through a single horn (eg. Martion Einhorn
370Hz - 20kHz, BD Designs Orphean MKIII 270Hz - 22kHz) and I just wonder how
they do it i...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

Among many outrages foolishness that are so common among the people who going high-end audio one of the most ridicules is use of Single-Ended Triodes and low sensitivity speakers. The people who have db-meters between their ears instead of brain are ...

At this point I am absolutely confident the there is difference in Sound between the properly sounding PP2000 that I had before and the “new” version of PP2000. Let juts for sake of illustration I will call it PP2011. The PP2011 is better soundin...

Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

Michael,
I never head Single Power gears, or ever herd this company. I kind of have very specific type of sound that am wiling to get out the headphones. It is hard to describe but it should be very-very soft and moist but still with upper bass horn...

Hey Romy... you could be right about the ALE's.. I certainly did like them, but when I went back to that familiar recording it was definitely shelved down low.. it would be easy to assume that I thought that they were "lightweight" because I had...

Well, the more I think about it then more I realized that I would like to try it. I’m contemplating to make 5-6 channels on single-stage Milq: 4 channels for each Macondo channel and 1-2 reserved for any perspective lower bass channel or for perspect...

Well, the game with a “better” 10" bass driver is over. After years of mind looking for the 10” light-coned, papered 20Hz drivers with higher sensitivity and after a month of quite active searching for such a driver I concluded that such a driver jut...

Ok, I found my RTA cable and did some very basic measurements of what Macondo does in the room. The results were in the direction that I anticipated but worth in amplitude. My right bass channel that that sited right next to the equipment bay has no ...

I have no experience with bass horns, but I suppose that any sound source into a given size room can excite its modes, hence a big bass horn or a line array of boxed woofers can be equally annoying in that regard. So if the idea of using horns is to ...

[quote user="haralanov"] Some time ago I also thought my upper bass channel is flawlessly integrated, but when I added another, symmetrically arranged UB driver (over my WR driver), I quickly understood the new configuration is MUCH more expressive a...

With that big horn covering such large frequency range I feel there would have a hole in the mid-range, or in the upper-bass. Not that I am supposing the information is not there, but it should not to be in there with reasonable "quality".I had not i...
