[quote user="Romy the Cat"]The subject of midbass nasal sound is very interesting. In addition to all OTHER aspects that might lead to midbass honk I would like to note that there is one that is in my view greatly overlooked – the precision of re...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

[quote user="Romy the Cat"]That sucks. I use to have a box of perhaps a dozen of YO186 but I did not see it for a while, pretty much from the time I moved to new house. I was listening today some of my “critical” reference stuff and concluded with ve...

Well, spent a few more hours to listening Avicenna. Although it has much better sound then from the wall but there are a lot of moments in this sound that I do not like. It is kind of freakish and demoralizing as Avicenna feeds system with absolutely...

[quote user="Canuck"]Romy Have you ever tried a PUREPOWER device feeding something like the Torus RM20 which has a huge transformer and then out to the components? The Torus stores a lot of energy in those huge transformers. Do you feel this ...

Hi Cat,
[quote user="Romy the Cat"]I used my typical “flash” techniques and discovered some leeks in that 50 years old enclosure. Sure it the leaks were there then it would be no “acoustic suspensions” and the driver would run further. So, fixed the...

[quote user="RonyWeissman"]A mid-bass horn for my Altec 515-8G drivers operating from 100-600hz [/quote]
Rony, I think your wish to have mid-bass horn with 515G is a bit faulty. A mid-bass horn for 515G shall be 50-600 Hz. Let me to explain. T...

[quote user="drdna"] I am kind of disappointed, since you typically advocate a very careful and systematic way of proceeding. What do you mean by extremely different positive?[/quote]Well, I it what it is. I am not DIY-Moron and I do not do und...

[quote user="floobydust"]Okay, I think I understand.... and thanks for the link on the YO-186... if I can ever locate some of these I'll be sure to grab some (hmmm, a trip to Russia perhaps). As tubes get very hot internally, there were some procedur...

[quote user="serenechaos"]The Festrex 5" was good in a limited range-- but get it out of that frequency range and or dynamic range and it has real problems. And that is as long as the part that the drivers are $40,000 / pair doesn't bother you....

I always say do not stress them they do not like it and I always hate third bass. The 10” are particularly are fragile with a power handling of a few watts. It is applicable pretty much to any lover MF driver that pushed to work with the “open b...

[quote user="nl"] However, these sorts of basshorns with twin 15" drivers and a very large mouth (larger than the cones of the drivers) have a long history. The Altec 210 cabinet, as used in the Altec A2 systems with two 515-type woofers, is a prime ...

Well, in context of a full-range speaker, like largest Wilsons or the similar, the answer would be unquestionably no. Even if we biamp those speakers then the LF still is too wide bandwidth and too geographically bind to the MF section. The wor...

Over the course of the last year I have been gently harassing my transformers-savvy surrounding trying to evangelize them into amorphous core. They stubbornly and perhaps stupidly resist. Some of them not…

I have been observing High-Efficiency loudspeakers for a while. I think I have seen/heard many of High-Efficiency endeavors and I think that I did develop acquired taste and some experiences about High-Efficiency results. So, I would like to pass som...

One of the challenges I see for my midbass horns is to minimize hf output. The goal is to operate the horn in a bandwidth where it can cross to the higher horns, and have each horn function in their best sounding manner. My drivers are Altec 515-16...

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

The people who use a single driver speaker believe the while their driver move back and forth for it also radiates a problem-free MF and HF. Near the same people believe that if an amp has capacitors with precious metals foil then it not only do ...

[quote user="Romy the Cat"]Anthony, I think you take the right this in a wrong way.
Sure the quality of the coupling caps is important but you truly shall not be worry
about it. Make the amp, get comfortable with it and then change the damn cap.

Well, the LL1627A is very good universal transformer with phenomenal flexibility (properly done - with section not with tabs) to load the output stage. It might be a good choice for a full-range amp at 200mA, though I would still prefer to have a tra...

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

[quote user="Ronnie"] I was under the impression that you did not at all electrically roll off the upper bass, and that the small throat would do all the (kinky) low passing. [/quote]
Nope I did roll of the upper bass channel as my driver goes all t...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

[quote user="Chirag"] The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. [/quote]
