Paul,
I have been working with trumpets since 1966 and horn speakers since 1975. I have built both and am pretty familiar with what they are, the similarities and the differences.If I had to pick THE major sin when thinking about all of the horns th...

The mini skirt analogy is a great fit. That is my experience.Or maybe like that stunning girl has small breasts and one has know the joy of a good handful. There are ways for enhancement and while one could get more, the girl is no more beautiful and...

Today’s prices in Hi-Fi do not base upon any other principle then “whatever market bears”. The luck of objective evaluation methods and the completely un-liberated market of Hi-Fi consumers make the “market bearing” principles being completely not ap...

Well, I thought there was a lot of this going on all along, but that we just haven't come up with much that is "universal" in the usual, "what do you recommend?" sense yet? Maybe this is because one person's Cu PIO is another person's...

[quote user="smith"]What a ridiculous waste of money![/quote]I completely disagree. Let's be honest here, the majority of audiophiles are atypical people (wierd, anal, eccentric, driven, insecure, etc.) and plenty of them require handholding, c...

[quote user="Paul S"]I think it is fair to say that no big speakers are going to "work" up to their potential without some serious effort expended in setting them up. IMO, this is no small matter, and Wilson obviously agrees,&nbs...

Maybe this is a mic problem, or a Sunfire problem. But, like I said way back when, the raised floor sink is not only the 5 Hz structural/footfall resonance, but it is uneven broadband + & - with respect to hi-fi, and the helluvit is that your ho...

Hi Daniel. I mean the window, after you sweep 10 seconds, and fuzz shows the IR. You can change the IR windowing on the preferences panel... like crop/cut the analyzed part of e.g. 1ms before the peak and then duration X behind the peak (here i asked...

Hi Romy,thank you for your answer. On weekend i will rebuild my amp for the 6E6P-DR. You are right, the tube datas shows that pin 8 is a screen. On D3A pin 8 is Grid 3 connected to screen.I will try it with pin 8 lifted and connected to ground. I hav...

what the thing become complicated. Of you drive ultra-low impedance with step

Yes, this is kind of strange. This is a cheap Blue Ray player; I think it is Sony BDP-S790 for $279. It played anything and supports live stream for pretty much anything. It is very comfortable to have it in opera room as video source. The picture is...

Adrian, Your Tesla comparison makes an unwarranted assumption. Tesla has professional management, an established supply chain and a stable production schedule. PP has none of that. It functions more as a sideline than a normal business. If people w...

[quote user="Romy the Cat"]It is interesting lately to think about a new listening room
as a concept. We looked at a few good house that for this or that reason did
not work for us and one had a very good listening room, just a phenomenal location

Romy, is there any way you can re-arrange tor re-configure the speakers in order to accommodate the stacked 15" drivers, or are you determined to push your speakers against the wall where they are now? I ask because I have heard stacked 15" drivers ...

[quote user="be"]Gregm, you wrote: "Yet, the best result -- i.e. most homogeneous sonically -- came from the thinner wires in interconnects."Did you use silver wire for your comparison?[/quote]I used copper in my example above. Later on, I received r...

[quote user="vuki"]Anyway, my plan was to make powerful triode NFBless amplifier for relatively small money. I'm really satisfied with what I did. Maybe I should have done GM70 SE, but what would be my next project then?[/quote] The GM70 is a bitch a...

It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE builds, but of the owner's design...

As I recall, the small ATCs at THE Show were the 19's, with the "long-throw" version of their otherwise-spectacular, domed MF driver, which their larger drivers employ, along with a range of woofers. I think they make amps for "consumers" now, too, ...
|
|
Yes, both ends of the spectrum are tough to integrate with a quality MF.Of course, electrostats have no "push", but they seem to do all right (understatement) just supplementing way up there, in an array.The thing is, the "big" ribbons and 'stat...

Actually (probably because of the phase coherence and tight dispersion control) they sound very good even with some basic equipments, like the small 300 USD Parasound zAmp for example, but I like them most with the pro MC2 Audio MC1250 amps or the Fr...
|
|
This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

Unbelievable idiot! Last night an audio guy visited me and I played to him some music. I was not sitting in the listening spot but what stroked me was now stringent and how shallow the playback sounded. I was waling around the listening room, scratch...

[quote user="Romy the Cat"] Elso, I failed
to calculate the very precise size of enclosure necessary to make all the
system work properly. Generally speaking, if you have a very very small
listening room and very up-close position, and if you ...

Macman, the “annoying peaks above the usable frequency range” is something that your specific installation might have in context of your room and your acoustic system location but it might not be a characteristic ...

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]

[quote user="be"]The paradox of the orchestra sound would be resolved if we asume that the audience (in the good seats) mostly hear the reflected sound, primarily from the wall behind the stage and that the players at the front follow the visual lead...

[quote user="rdrysdale"]So how do you suppose the proper DPoLS can be located? With a system like Steve Schell and I are working with, everything weighs hundreds of pounds and to properly evaluate changes would take days, maybe even weeks f...

[quote user="kodomo"]Hey Anthony,Your project is going on track (and looks like a very good track)! Just a reminder about the room acoustics. You are talking about bass frequencies which are as dependent to the room as the speaker! Before installing...
|
|
As a practical matter any room length shorter than 60 feet (20 Hz) is going to chop bass note waves - the smaller the room the higher the frequency with wave chopping. Also because of the size of the bass note waves, human ears have trouble locat...
