As another of the contributors / perpetrators i have to chip in too.It's my Raal's, S2's and stands that can be seen.Great project and fun to do and as Adan says it opened some eyes. Others seemed to have little or no time for it, as it is incomprehe...

Dear Romy,
Thank you for the commentary and the advice with regards to the need to have a COGNITIVE ORDER OF SUCCESSION and to test with another speaker in situ first.
Given the varying degrees of how different individuals process COGNITI...

First of all, season's greetings to all. I have been thinking about this issue for a few months now and was reluctant to post a question in case it was premature! There must always be some niggling doubt whether any real estate adventure will materia...

[quote user="Romy the Cat"]I still feel that a complementary upper bass channel is begging to be used in this system. [/quote]Yes, Romy, the upperbass channel is absolute mandatory. My comments were only about the particular driver, nothing more than...

As the builder behind these horns, I can answer some of your questions. It's true, I was primarily focused on the woodworking/building side, and now I'm experimenting with amplification and crossovers. I can't speak authoritatively on those subjects...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

It seems ironic that the path to bringing the single-channel DSET/narrow band horn idea to market would invlove traditional marketing per se as much as the melding of evolved listening with cutting edge technology. While there is rote work...

John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...

[quote user="Romy the Cat"]Ok, can you in subjective trims describe what do you feel is wrong with your sound. disregard the speakers and channels, tell juts your pure reaction to what it is. The cat[/quote]Romy, I now see you were asking a totally d...

I'm working on a project that may be of interest to others, and thought posting to this old thread was a better way than beginning a new post.I use speaker level passive crossovers, between multi-amps (not DSET) and drivers. My desire is to move the...

[quote user="Romy the Cat"] [/quote]I really do not know what is going on and how to explain the phenomena; I just dump it to you “as is”. Because of multiple reasons I decided to drain the Milq’s power supply when the amp shits down. I have a...

Allo,Well, the divider may certainly be responsible for some softening of transients - in particualr, what values are you using there?Also, the received wisdom is that silver micas are created far from equal; no experience with them myself but I beli...

I had a Walker Proscenium turntable with various cartridges. About twenty years ago I converted all my vinyl to 24/96 files and have never looked back. As far as dsp processing, the Trinnov altitude does a superb job of either recreating the hall sou...

Yes, referring to my initial post on the thread: something in the Super Melquiades is very freaky. I did not use it for a week and this morning I tuned it on. The amp generally does not sound good for a first 10 minutes and reaches it’s stable ...

[quote user="op.9"]I now run my 'tweeter' amp 1st order high pass at 2200hz (driving BMS 4540nd in 1500hz leCleach horn) so my impressions might have some bearing on Romy's new amps. I was playing around with operating points and components in my sin...

We enter a complicated region as the lower driver we go the drivers could be used for different purposes and it is very hard to generalize. A 10-incher might be MF driver and LF driver. In my past I experimented with few MF 10-inchers, including some...

Well, it looks I’m near finding a more or less acceptable setting for the T350 tweeter. Ironically and completely accidentally it is not far form I use to be. It is still on the slope at 20Hz (since the T350 is pretty dead at 16kHz) but now it is &nb...

Paul McGowan, the head of PS Audio send his newsletter with his comments about SACD. The comments are childish and in many way absolutely ignorant. I hate what the industry professionals twist the facts and go into pure falsification in order to ...

[quote user="cv"]Little suggestion should all else fail - you could have a rudimentary phase plug machined that would give you the same (or similar) compression ratio as the original but only one annular exit path. This might preserve the driver char...

[quote user="Romy the Cat"]Brian, and how do you find your MOSFET behaves compare the 12AX7-based cathode follower?[/quote]Romy, I have yet to try. Only got them on recommendation very recently. They're cheap enough to try in a B9A plug-in without al...

Likely, the wider ribbons are less good for HF-only than a long, narrow ribbon, like the G3 and G3Si use. Across the board, the larger the ribbon gets (and the lower the ribbon is made to go), the worse the dynamics at a&nbs...

To my big surprise the Pacific tuned out to be an absolutely wonderful 16-bit DAC - the only one that migh compete with by Bidat. It does not go into max weigh of lowest end as some other best converters do but it has such an interesting and reach “e...

Yes of course, rule going to be very much in play and certainly it will be impacted by specific response right and left channels to a given location. Even though the location is hugely variable and the speakers might be moved with the freedom of 6-7 ...

I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...
