This weekend I discover interesting phenomena on which I did not pay attention before. The Montrealian Charles Dutoit conducted this weekend Boston symphony. I was listening the broadcast, recording it as usually. It was ...

I do not mean to be negative and criticize Romy, but he is wrong on surround sound. It is the implementation and not the concept which should cause vomiting, like with the vast majority of two track recording which are unlistenable. With the rig...

[quote user="twogoodears"]…. they seem to operate in a very specialized narrow bandwidth... So, my (humble) advice - based on my direct experience - would be: if the case, try to use Goto as 4 ways, not the more common 3 ways... also if Tanaka-san is...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

I really do not what is gong on there and why. Thorsten's comment that line-level crossovers do not act like speakers’ level crossover confirms what I feel and what some other people suggested me. Yes, the reactance of the crossover component, the in...

[quote user="floobydust"] Integrating multiple amplifier sections and drivers is always a challenge. Doing it with different topologies and OPTs adds some additional complexity due to the difference in response characteristics. Crossover design...

Okay... I also downloaded the original Milq SET amplifier PDF and have looked at it in detail as well as the 6-channel adaptation (DSET) and I understand where you're going with it... or so I think. In my particular situation, I've owned two pair of ...

This thread is a derivation from the thread:
An ultimate transformer within a narrow bandwidth?
Since my Super Milquades is up and running I’m wondering what can I do with the output transformer at HF channel in order to push the envelop of “possi...

[quote user="Romy the Cat"]I always was “concerned” about those large high voltage triodes: 211, 845, GM70…. They kind of different… The 845 always was brutal and not elegant, 210 was elegant but not sophisticated, and the GM70 was sophisticate...

I would bet that Romy prefers to sit from mid hall to the back of the hall, as I do, and our penchant for for large orchestral music. Thus, while sitting up front gives the orchestra stage maybe 120 degrees wide, with little hall sound, it tends...

I am with skepticism treat that information about those WE demos. WE never did any interesting playback system solutions that might be stimulating in today home audio environment. At the time when WE was operational the requirements were very differe...

Hello,
I've never had an SET amplifier in my system. Having high efficiency horns (106 db on average down to 100Hz ) I have tried a number of solid state and tube amplifiers, and I am aware of their sound in my system. ...

Keith,
Thanks, I do not see any needs to discuss anything with Ralph – I am not a prospective buyer and what I had interest personally about Gammas I have already understood. It does look like those Cessaros people took horns eventually seriou...

[quote user="de charlus"]Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far fro...

Why not? Wilson for many years each 2-3 years updates own flagman. They had Grand Slamm’s number of revisions where they constantly change tweeters, other driver and resistors in crossovers, introducing new rounds of opportunities for the custome...

Quotes from Romy in blue: "...Anyhow, I do not know at which stage your project is what I think you are somewhere in a process of integrating the drivers..."I would like to stabilize the system, and listen to the existing horns, while ...

[quote user="kodomo"]Hey Anthony,Your project is going on track (and looks like a very good track)! Just a reminder about the room acoustics. You are talking about bass frequencies which are as dependent to the room as the speaker! Before installing...

[quote user="kodomo"]Great project! I have a similar project going on. Your frame ideas are looking beautiful, however I decided to take a more utilitarian road. I can adjust all my channels in horizontal or vertical axis. I am finishing my crossover...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

Ok, I loaded the S3 driver into the new multicells, use my extra of bas sections as a pedestal for multicell, connected 2 extra bass channels to ULF amp and the multicells to full range amps with no crossovers. Yes, I got a VERY good width and th...

Adrian,
This it truly complicated question. The Titans’ upperbass (the better one, curved, with 12” driver) is not realty HF capable and it makes a MF driver need to go all the way down to probably 500Hz (I do not know what Bruce dies in the crossov...

[quote user="stuck.wilson"]In this thread, you previously said--
12) If a filter requires a phase inversion then it is preferable to flood crossover point with amplitude and do not invert phase.
What exactly do you mean by this and how's it work?[/...

Thanks, jtavan.
It was educational. I made some first steps already. I made a slow 233MHz (and presumable it would have lower noise with lower speed) machine with no fans, and a large passive radiator on SPU. Formatted it and loaded Win2K Pro St4. S...
