Excellent news regarding this morning's discoveries. jd wrote:"...Are you able to say whether the problem is due to the horn position relative to the room, or to throat diameter relative to the driver diameter?..."Yes, a stupidly phrased question, bu...

[quote user=" Jonathan Valin"] Third, in Munich, because of the severely limited amount of time available for setup (and the severely limited space to set up in), Wolf DSP’d the U3s for phase but did not DSP them for time alignment.... In Cali, the U...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

Last week found that the distortion I was having was due to some small separations of the woofer cone from the surround suspension probably from age and playing too loud. Applied the glue to them received from English tannoy dealer and distortion...

[quote user="drdna"] 1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which is based initially on a single-driver type backloaded horn. To me this suggested that the seller was seeking the benefit...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

Romy,
Why preface my comments ? I've had the same system for 10 years basically. I do use digital crossovers but the 'Class D' NuForce amps are not digital at all. And the NuForce amps don't sound like stereotypical Class D amps, they are very quie...

Hi Romy,So, six channels are now operational in the first DSET. By up I mean the anode voltages on all tubes is about right and the currents are in the ballpark of where they need to be. I am yet to check the DC Offset so hopefully that goes ok.Ini...

[quote user="peter foster"] The TU-X1 sounds to me as though there is a dolby processing happening even when the dolby feature is off. [/quote]You might check if your country decoding switch is not in a wrong setting. It located at the very top of th...

TwoGoodEars posted at his blog a report about is listening session or some kind of installation. I still have no idea who’s installation it is: Jean Hiraga or Be Yamamura. Nevertheless, I think it very much worth to look into it.

[quote user="cv"] I gather the Acapella plasma tweeters have a catalyst so you don't get the nasty oxides/ozone etc. Got some old ionofanes on the way so will know soon how well they freshen up the room... They are self-amplified so efficiency ...

[quote user="jessie.dazzle"]….. sit back and conclude that, yes, damn it, a pair of good straight Mid-Bass horns is exactly what you need. My reasons are of course somewhat selfish... as I won't like being alone in needing a non-digital delay solutio...

I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "my own" care, "my own" taste, ...

Jessie, in the configurations of the horns and derivers that you are building your mid channels do not exposed too much to stresses. It is not that you have a situation when 1/4 octave more and less will send your channels into suffocation - your hor...

Jorge,
You're right about using identical amps. No doubt.
I have not used Dr. Edgar's passive network but I have tried conventional passive networks on Edgarhorns. They worked alright.
And I have...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

fair enough- you're absolutely right, i didn't!it's difficult to get that perspective on sonics without legitimate guideposts-- even with a lifetime of playing and recording music, it's difficult to know what the parameters of recorded sound ar...

I got an email from a site visitor informing me that there us a set of cheap ALE drivers at London Craigslist: http://london.craigslist.co.uk/eld/4435844980.html(copy locally to have it available after the Craigslist posting will be gone) "ALE Acoust...

For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to accomplish. I want to reinstat...

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...

[quote user="Romy the Cat"]Even though quantivly and structurally bass is correct but it is not what I am looking. [/quote] Last night I got rid the SMS crossover. I built in the 28Hz, 12dB per octave crossover in the Yamaha B2 amp that I use f...

This is funny and depressing at the same time. Two readers of my site sent me unhappy emails informing me that my latest posts” “A typical upperbass horn mistake.” was juts my foolishness. Whatever they said boils down to following:

[quote user="rdrysdale"] We are using about an 18 foot path for the sub. What we need is for some smart electronics guy to design and build a processor just strictly for time correction, and nothing else, no EQ, or crossover built in. [/quote]
Hey, ...

Prior to three days ago, i was almost ready to give up on the Dannoy's as I couldn't get close to the sound heard at Romy's with his setup of the same speakers. Then i was able to add my newly obtained Yamaha B2 amps, and was once m...

Well, I never felt that for prototyping I need more then one-channels crossover as by use of the poor sounding prototyping crossovers I never look at the system in it’s entirely but rather for the “technical listing” of just two channels that I...
