And you are right that it also has a regulator within the power supply. This is stated within the owner's manual but it would not allow me to copy it. They use rather convoluted language. Maybe this is the result of translation?To quote from the r...

Back in end of 90s, we read articles by Thomas Dunker, Joe Roberts, Bruce Edgar, and many others (some of them were designers and some of them just publicists) who were trying to persuade that horns are some kind of advantageous topology and that...

For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

If you are an adherent to single-ended amplifiers and high-efficiency loudspeakers then undoubtedly you came across to the thought what to do with LF sections and how to drive them. The high sensitivity at LF comes only along with the non-resolvable ...

[quote user="Paul S"]"High-efficiency electrostatic speakers"??? Is this not an oxymoron? My friend, Mark, who sometimes visits and posts in this form, has gigantic Sound Lab 'stats. He hates SS, and he uses VTL Wotan tube amps to drive them, 1.200W ...

Paul S:DSET is a very high power solution to a question that I only have a very primitive understanding of. It is not right for me at this time.I would prefer if the model etc. of my speakers not be involved in this discussion. I know I am committing...

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 ...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

[quote user="Paul S"]Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter ...

The cool thing is how Lamm figured out how to get one's attention off the window, albeit, apparently, through a fairly didactic program of "organizing", "correcting" and/or "mitigating" certain information he realized contributed to that particular d...

I would have to say that loosing Gabo is a far bigger tragedy than damaging any sort of reputation I might have.About making horns I don’t yet see this obsession as a full time career, and if you ask I just as well would not be able to answer what dr...

(sorry, this is supposed to be posted in the questions and answers colume but I must be so stupid to have it posted here and now I don't know how to move it there.)Hi Romy,How are you! This is Welborne, from far across the ocean, Hong Kong. I have k...

I've used both tube and solid-state rectification over the years and much is well documented for power supplies, i.e., old ARRL manuals, Tube manuals, etc.. In most cases small value filter caps were shown, as you really couldn't get much in la...

[quote user="Romy the Cat"]I do not care about all of Nilsson Pass amps; I feel that all the same and all are very sub-qualified. A few years back Mr. Pass went for his low-powered SS single-ended amps and they might be more interesting. The Cat[/qu...

Another particle of a good Horn Propaganda. It was published in Sound Practices in 1994 and written by Joe Roberts. I disagree with quite many of the author’s statements but his strategic view that the majority of the horns and the horn installations...

Romy, I'm very proud that you are following me and commenting my achievements.I just don't understand why you are doing it in a manner that you are the one and others are idiots and morons. If you don't understand others, you can ask them questions. ...

I own a pair of the Total VictoryIII that pair nicely with my room due to the inside firing woofer (tames my room nodes). The marketing of the products uses tremendous hyperbole (words like 'breakthrough' appear often with regard to speakers, c...

Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

[quote user="manisandher"]As I alluded to before, I'm at risk of becoming a DSET convert - it's all very well having a nice low-powered amp, but what the hell do you use with it? Are there any decent high-sensitivity FR speakers out there? Or is ...

Hi Romy. Have you tried a large cone high efficiency tweeter? I have used a Saba 4 inch diameter 'green cone' 99 dB/w without a horn and found it to be interesting. Have you tried some kind of horn loading with such a tweeter? Steve...

You are very much correct. All existing critical mass of knowledge and practices about hors is completely irrelevant for a home use and partially if user’s demands are more evolved then a typically-Moronic: “look the saxophone sounds like the real on...

I've been following this line (mostly the big one) with great interest since it was first mentioned.It's definitely the most interesting high-efficiency horn line available, as far as I can see. I've been asked to look at distributing/marketing...

Is this type of driver not similar to those used in headphone?. Very high efficiency, wide bandwidth, very low XMAX. The lightest and fastest are probably the orthodynamic type like FOSTEX RP, HiFiMAN or Audeze LCD2....

The price to pay for it's high mu is the A2 operation. Zero crossing, big driver, etc.Why not 304tl? mu of 12, Rp of 1-1.5k, so a very good current efficiency and not so demandinginduction-wise. It would require a 3-stage design though......

Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...
