Ok, I did play today with the MiniMe. I have to tell that then it turn black I kind got soften with it does not look to me as large and violent as I initially thought. I made some measurement and some listening. I peaty much know what I want to be an...

Petar, thanks for the pic posting link (which I've read over and over), but my problem posting pictures is my ancient browser, so that's another task. Again, there's really not much of what one would like to see that I can show, short of disassem...

[quote user="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

Following my recent “new objectives” with tweeters (partially covered in the last posts of the following thread)

[quote user="Romy the Cat"] Why do you feel that uniform "floating" rotation is possible only with N amount of drives? [/quote]I don't feel it's the only way :-)[quote user="Romy the Cat"]Let look in this deeper. A single drive would it be idlers o...

Haralanov, good post, clearly indicative to a person who uses single-driver speakers. :-) I would have a LOT to say about it. The subject was very deeply researched by me in 2001-2002, before I had my site. From my current standing I disagree with yo...

Well, people know my unhealthy love to “invent” the things and to grant to the “inventions” stupid naming conventions. Guilty but do not care. Here is another bright idea – the DPDP consept.
Audio people spend time socializing online, patting ...

In the TAS that I bought because the Lamm ML3/LL1 review I found Jim Smith add about a new Engström & Engström Lars amp from Sweden. Jim tells the story about the Engströms and about the 20 Lars’s rules that reportedly assure “good sound”. Th...

Hey Romy!Been awhile... But I been sooooo busy!Got some preliminary news to post regarding Lowthers new DX65:For many months I've been corresponding with Jon at Lowther

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...

[quote user="oxric"]I would have been tempted to maximise space above for use by 4 midbass 15" drivers, 2 per side maybe in separate enclosures you can can move each module independently of the other.But probably too late for that as you have ordered...

[quote user="Romy the Cat"]
what do you see fundamentally appealing in the symmetry of the differential circuits and what the relations between Sound the symmetry? Not to mention that the perfectly symmetric circuits do not exists. I’m very far form...

[quote user="drdna"] Well, and I have a dozen of them sitting here next to my desk while I am building my Milq amp s-l-o-w-l-y so I guess I will discover my audio intelligence level sometime after the New Year.[/quote]
That is so cool that you...

Antonio,Works just fine with ported, unported or open baffle. The process works on the boundary layer of the cone. This is the very thin area between cone material and air. The actual mechanism just disallows energy trapped in this zone from reflecti...

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...

Certainly, this sincere invitation was offered in part because they found you an interesting Cat, but I think that the offer was also inspired by the fact that you are writing pages of critique on items that you have not, in fact, ever heard.My Korea...

Yep, Stefano, it looks like we do have similar views about the subjects we touched. Let go back to exploring one of the terra incognito of compression driver – the sound of Goto.
I would insist is that to judge sound of Goto driver from the installa...

Although Levinson appears to have missed the boat with respect to musical content, he did show what can be done with Sound, per se. I still use his demos as a sort of mental yardstick with respect to the quality of the sound he did "reproduce".With ...

[quote user="rowuk"]I have experimented
with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that
ceramic drivers with SETs that I have heard being suboptimal, but after a year
of DSEP, at least for my use case, I am quite conten...

[quote user="Paul S"]I have begun to see a pattern of diminishing net returns with respect to the smaller SETs, to the point where I wonder if their "potential" can ever be practically realized as Music in Full Glory. Lastly, the choice of an ou...

Alex, contrary to the numerous speculation that many people more or less reasonably spread about the subject, my experience indicates that there are no such a things as “preferable crossover frequencies". The chosen optimum crossover frequencies are...

Nine years ago, when I posted the initial post in this
thread the Aries Cerat was a different company with different products.
As I understand in 2014 they changed a lot and today they have a speaker that I
would like to talk a little: Aries Cera...

Thanks Romy,[quote]With midbass the total sound of channel is about 20% come from the driver and the rest comes from the horn design, channels integration methods, room integration methods and a few other factors.[/quote]Now I got why exactly midbass...

Romy, I'll limit my answer to only speaker-related problems. 1) Still too bright sound. Not hard or edgy, just too much top end. My local guy suggested trying a single resistor in series, rather than an L-pad, to tone down the tweet...

Yes, Jonathan,
I have seen this resemblance with JBL in the shape of the back plate but it does not mean anything. The curved back magnetic path make a lot of sense, so he might adopt it from JBL. There is nothing wrong with it.
I do not k...

Whoever implemented and experimented with my slicing of lower MF range by 3 channels (Upperbass, Fundamentals, and MF) know how powerful it might be. Changing loading and volume of each of the channels it is possible to write any sound one might ...

Romy,
You got it all backwards but thanks for your visual approach to the subject.
I really meant to illustrate the fact that Point Source does not exist in "real life" and that it's analogy with a single driver makes no sense (then there is the ...

The 6sn7 is a fine amplification tube for use in preamps or gain stages, but it has way too high of an output impedance for driving power tubes. This is my personal preference. It also depends greatly on the topology. Maybe George u...

[quote user="Paul S"] Given speakers that can be driven dynamically by single stage amplification, there remain a host of issues, and among those issues is color. Most compression drivers are color-challenged to begin with…[/quote]
