Rick, as I "remmember", the PP output waveform was a "perfect" squarewave, in terms of shape, but it's pulsed. And I think Romy said it worked with a load of up to 60% of "capacity". Does a different regenerator have to "work the same" to "sound as g...

[quote user="Serge"]Romy consider that the engineers who did your Altecs in their worst nightmare could not imagine their lovely cinema speakers would be used with solid state amplifier which badly distorts on LOW power levels. It has 100 crappy watt...

It is not about “how low can the 600hz horn go before running in to problems” but rather a specific if of Vitavox S2 driver. The S2 with plastic suspension has secondary resonance at 1250 cycles (you might read about in details in my S2 thread). So...

Dear Romy,The tracks are correctly listed.Yes, the tracks are varied and some are not good recordings at all. BUT if you want to listen to Billy Bean play guitar or you want to hear Louis Stewart's first recording as an 18 year old then you hav...

In my experience even the most shitty system plays a certain recording very well, whenever I go to listen to a playback the owner puts those special recordings that sound great on his system, (we all have heard them endlessly on shows). I have a cl...

[quote user="anthony"]My RAAL Lazy Ribbon has ended up needing a 1st order high pass filter to match the midrange S2 which is so much more convenient than third or fourth order as initially intended.[/quote]
In my case I found that RAAL ribbon wit...

[quote user="tuga"] Romy,On the subject of speaker design, I don't think you'll disagree if I say that your "quest for a better monitor" was unsuccessful.You mentionaed at the time that the speakers should respect the following:1) Perform correct in ...

I presume that whoever read this thread have gone over my comments about the Sound of the former PurePower 1050, particulary my comments about the PurePower’s “Super Texture” at the page #5 of this thread. This controversial “Super Texture” was my ma...

It uses looks like a custom paper woofer and a custom paper tweeter, both geometrically naturally aligned, behind first order crossovers, unfortunate...

This whole 833 A2 concept, given the constraints,is a no go. When driven positive, the grid equivalent resistance drops down to 1/transconductance level. For 833, being a high-gm tube,this can be as low as 100R. In order not to distort significantly ...

IMO, any sonic benefits from running Lowthers stock are totally swamped by excessive, ragged response that is generally (but not steadily...) rising - a lot - toward HF. There have been many ideas for "taming the Lowther", and here is another one, b...

If you visited this site before 2004, when I conversed it to audio site then you remember that it was performances-centric site. It was structured by composers, and each (let say some) composition had a list of reported...

Good luck getting midrange from F120A for non annoying monitors. Seems reasonable to expect, many people have been very happy with these drivers... I haven't tried this specific driver, but have spent some time trying to get a simila...

I have run each of these for long periods and can validly comment.My power amp circuitry is a 6N1 based Mu Follower driving a 2A3 in turn driving a 3K Tamura amorphous core OPT.The 6N1 tube is a special military type that is not freely available.Ther...

OK, the first think first. The second and the their images from the tope that were marked 2000Hz and 40000Hz are in fact 20.000Hz and 40.000Hz. I just lost a zero when I typed it. I have corrected the labels
Jim, it is a good question about the inpu...

Antonio,
The Amati's tweeter and the rest of the similar tweeters are totally out of game form the prospective of my post above. The Amati's tweeters kick in at 2.500 with first order (heavily compensated), it means that those tweeters run the imple...

Chris, I have no experience with good sounding SS amplifier that might drive high sensitive horns. I also have no expertise to build such an amp. From what I trued before I have learned that in order to sound more or less acceptable the SS should run...

The speakers i've got are JBL studio monitors using a 2420 (118dbwm 16O) on top and a 2231 (93dbwm, 8O) on the bottom, which already accomodate bi amping, though like i mentioned a midrange driver would probably be a good idea and so a six way amp wo...

What I would like to see is as usually does not exist but I would like to see a regular cone full-range loudspeaker objectionably made for use with a single powerful SET.
What I have in mind is a sealed enclosure the size of Dunlavy V or VI, 4-5 way...

Looks like I'm back into this again, since, all of a sudden, out of nowhere, Yoshi up and sent me his "neutered" Reps 1 drivers (he surgically removed the whizzers).I started turning my existing Basszilla components and these guys together ...

It is OK, Item. It is a common for people who sell audio to be not completely informed what they are selling. That comes with territory. You might discover with time that audio is much more interning then just to dump a pile of BS on people and to ma...

[quote user="slowmotion"]How was the lower midrange affected by the tweeter removal? [/quote]Now the S2 is crossed at 700Hz with first order where the upper bass begin to dive. Since I use now a new line-level (yes my buffer project is over quite suc...

Angelo, I do not think this site add anything applied to the subject. I personally do not feel that upper bass horns require any phase plugs; quite in contrary they are dreadful for upper bass horns. When a straight horn employed then the horn does n...

[quote user="noviygera"]I feel that the best candidates are metal springs. 1. They won't compress or deteriorate quickly.2. They work good in the used freq. range.3. Easy to replace. Easy to tune by adding or removing springs.4. Easy to float the ent...

I was thinking and fantasizing about finishing of my midbass horn. My first idea was to paint it internally with the same color as my cathedral room. Perhaps a lighter grade of paint in the end as the horn goes dark. As the only mouths of the horns w...

Jessie, as it happens, I find my own best listening position varies somewhat these days, depending on what I'm listening to or for. For the best overall energy in my fairly energetic room, it is with my ears about 1 1/2 m off the...

Romy,If you look behind the physical time alignment and start discussion about relative time alignment, that is a good start. Thing puzzle me about your view and comment of GOTO system setup that you have seen on pictures or web. How will you know ...
