Thanks for the extensive reply. I wish I knew exactly the use the preamp is doing of them and if they could be safely replaced by those alternatives you mention. I believe they're regulators within the power supply. The problem with them is not burni...

Yes, the "bottom drops out" of the "IB" depending on whether or how it's "opened", and one way or another, the cabinet may or may not "assist" the driver at some point. This is where one has to decide how much to ask from the particular driver or dri...

Consigned to the root cellar? In such a small space, "cranking it up" is a relative term, but I think this could be more interesting than headphones. Anyway, there's no substitute for trial and error. I would say, basically, use a good front end a...

But who says an A2-capable amp should actually be driven into A2 in use? I thought you planned to operate the amp well within its limits, to get the DHT benefits without subjecting the amp to the sorts of stress that always spoils these little thing...

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...

Well said, Haralanov. It might be nice to say also, for further clarity, that the wide-range MF channel is not part of a 3-way system, because no wide-range-driver-with-extended-upper-end is "enough" without help as it goes down, toward and into th...

Romy,Of course you are right. I would not expect you to advise me on whom to marry. I will indeed experiment as I was always planning to. I will place my speakers and play them, listen to the room, get naked, dance a little dance and hope for inspira...

I like those ideas for tuning texture, and would add the way the surround is done and how it is clamped/bedded, which might be relatively easy to control, maybe even on the fly (with some sort of cam, for example). So far, it seems to work best to "...

[quote user="Paul S"]The frustrating thing for me while messing with the mounting screw tensions was that there was never a universal "best" setting that involved looseness, but it would all change with different sources or at different volume settin...

[quote user="Paul S"]Anthony, this is a very smart installation, IMO, because you have not "over-committed" to areas where you have work left to do, and areas you have committed to are flexible enough to allow adjustments you will likely need to do. ...

Josh, thanks for sharing. Of course I have not listened to these speakers, but I can say their marketing looks and reads pretty much the same as other manufacturers who aim at wealthy nerds who want to own "the best". Altec-Lansing was very much li...

The thing about horns is, "developing" them consumes a lot in terms of time and materials, and they are expensive to materialize. SPL modeling programs can be great for getting in the ballpark, but YMMV when it comes to "level of demands" from a hi-f...

Since no driver is actually full range, driver selection is partly conditioned by how well it plays with the other drivers it will be used with, and - very certainly - the crossovers it will be used with, also baffle shape(s) and size(s), amps(s), an...

I found the frequently-power-starved Sound Lab A1s and A3s to be audibly more amp-connected than some other speakers, including some that do not get as loud in absolute terms. Although horns -generally speaking - may "need" SET to get...

Not having heard either the 1-stage 6E5P or the YO186 DHT, I can't comment on any comparison of imaging characteristics between any two circuit configurtions involving these tubes/circuits. All I can do is offer that DHT + good electricity can d...

Since the greatest differences in audio are among listeners, there is no need to argue whether such things are audible.However: While it no stretch to say from personal experience that such things are audible, it is very much a stretch to s...

Somehow the front runners in the horn field seem to have entered a time warp. At least we tried mightily to overcome/mitigate "horn sound", back in the day.With all the promise horns offer in terms of dynamics, all I wanted was a decent demonst...
|
|
Josh, I never tried exactly what you are describing, and I don't understand how it would "cancel errors" in real life, but you should try it. For a similar-but- opposite take, have you seen the Danley multi-driver horns yet? There's more on these -...

Maybe the upper midrange horn became like a paper cone speaker. Best sound I ever made, and it looks like this. It had the same ring to it as the magical SABA fullrange speakers - made of paper. But below 500Hz, I must use solid wood. The Fanes are t...

Ok, so I'm not really going to talk about the show itself, but more of some interesting things I learned. Yes, I did have a room, but that's not the point. I was able to borrow some speakers from Azzolina. They are of the unusual Lo...

Perhaps there are ways to horn load Lowthers that do not screw up the sound, but I don't know of any, and there are other reasons, as well, for not asking LF from Lowthers.For me the best thing about the high-pass-limited Lowther DX4 in OB is th...

[quote user="Paul S"]At this pointIi think it's fair to say that if you have ML2s with "reasonably efficient" speakers then you can safely just hew to whatever works best with the ML2s and toss the rest, because in that case "the rest" is not worth k...
|

Thanks, Romy. I did notice that there is more "apparent volume" at the same gain setting on the pre, and harmonics certainly come into better perspective. Also, the image opens up more vertically, which is a nice effect. I could alw...

Well, Yoshi, at least you're on your way to getting your speakers more of a piece.I have for some time warned people against a mix-n-match approach with the DEBZs, based on my early experiments with them, and it is true enough to say, I think, that&n...

I certainly hope more people will get going on the different versions of the Melquiades amps so I can learn more about them. So far, this site is a crash course! I just hope everyone is paying attention when thye read here, over and over,...

[quote user="Joe Roberts"] Yeah, but plywood is cheap and the result is audibly noticeable. Baffle extensions were recommended for all of the Altec VOT cabinets too. Make a big improvement for cheap if you have the space.
As the frequency dec...

Tonight I listened in my truck to the "local" classical station playing a Mozart piano concerto I did not recognize ibefore I lost it. As I got closer to home, there was the familiar ghosting and then adjacent station override. The reason...

That is certainly a new idea. Unless it is really easy to take it out and start over, I would not do it. I just have no idea whether or not it will work without making noise. I have always just used mathematical calculatio...
