...to obsess about speaker wire. Thinking about this a little more I realise that my preference for foil cables has always been in relation to speakers with passive crossovers. DSET is much more simple, the amplifier is driving the transducer direc...

Well, You really need to figure out what you want out of your speakers. There are some questions I would ask myself if I were in your position:1. You can eliminate a lot of speakers based on their size, since they should be mat...

I had the opportunity to hear the magico ultimo, in san Francisco. After i heard it, i read the article in absolute sound, and i must say that the article describes accurately the sound of this system. The room is relatively small for that big ...

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...

What did you know; I was in Barnes & Noble and bought a first for quite long time September TAS magazine. I do not subscribe audio publications but seldom buy them. Since I did not do it for as long time I though it will be entertaining. It...

hi Koshka Sr...the reply has been illustrative as usual... when you> finish you medical school you will be searching in very different price range. :-) yes, but then we have residency....5, maybe 7 years of *relative* poverty :-O > When you ent...

Petar,
What you say doe make sense but I think I am in a different environment. I use the driver about what I have no knowledge at all, I do not even know at this point where to source them. I will drive the thing lower then the drivers resonance fr...

[QUOTE]I have to admit that it is not a good idea to judge a loudspeaker based upon somebody else’s comment[/QUOTE]Yet you continue to do it again and again... why? You know its bogus, I know its bogus, they know it is bogus. Dude, it is BOGUS. Just ...

So, the first DSET is still downstairs on the electronics bench and I am back to work for a while, but not too hard and not for too long (I hope). I've added all the filters and checked and tested and changed some more things and decided that it was...

I was informed that there is a new Estelon Extreme loudspeaker out there that costs ¼ million dollars. Not with interest I read about it http://www.estelon.com…and concluded that this is as idiotic as it get. Nope, I did not listen it and I have ...

The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wouldn't call it an "open baf...

The Rockports have a very light platter and a carbon Arm....the one I listened to was the latest, it had simply no Bass reproduction, nada, nothing and the Arm resonances are also inferior to any energy transfer from any cartridge. The lead wires are...

Romy, I have been trying to explain to myself what happened and how I got to it and trying to recreate this wonderful boiling point.
I tried to make a write up of all the steps needed in order to make it happen, but it is ever so elusive. I ...

With stereo you hear sound from more than one source (speaker) and the sound from each source is very nearly the same except for some variations in amplitude of certain frequencies and some phase differences which occur becau...

This is an article from Thomas Dunker's site (available in my Links Section) and presumably written by him. Although I slightly disagree with some of the statements he made about the horns “imaging” and some others but generally it is very good...

[quote user="drdna"]I have found the next obvious glaring problem, which is contributing to the muddy sound I described earlier. There is a mismatch between the two channels. The right channel is very slightly softer than the left with a ...

Robert, actually in case of Grand Utopia you was remarkably close mentining the ‘magic tape measure’ option. You see, they demoed Utopia in looks like a large room and they band the Utopia’s axis’s only for demonstration purposes. In this configurati...

I would agree that the Lowther is not hard to beat but the question is where and in whose mind does this competition exist? Is the Lowther, Manger, or other full range single driver in competition with different multi-driver approaches, other single ...

I never heard Everests and I hardly feel that I ever will hear them in a reasonable installation as the people who would use Everests most likely will be the people of “different type”. Still, I wonder if the Everests are the JBL’s 21st century glori...

After thinking about this for a while, I have had a thought that should be relatively easy for anyone motivated to explore and I would be interested to see what others on this forum observe from such experiments.Fundamentally I think the injection ch...

If we are taking about multi-way horn-loaded acoustic system then in my view is it very important to plan the development in a specific order. Any deviations from the order are perfectly fine but they will affect cost/time/efforts of the project. Thi...

I hear a rumor that Sadurni Acoustics was presented at recent Chicago audio show. Interesting, that Jorge went out of closet and decided to invest in full time career of speaker making. I wish to extend to him a full my full condolences an d my great...

I was trying to strategize what would I do it tomorrow someone get in touch with me and offer my $50K. In another words what would I do to convert the Altec 19 to Cetla Ledom?This is an interesting discussion itself as it gives a blueprint for me...

[quote user="tuga"] Hello Romy, Could you elaborate a bit on your experience with the toeing in of horns subject. My square mouth horns are probably even trickier than round horns to fine tune as the higher frequencies seems to radiate in a flowery (...

I've never understood the continual need to get equipment to have ever wider frequency response, to me (but then I'm a complete technonumpty) this just seems to be an exercise in chasing numbers to impress those that are impressed by spec sheets.&nbs...

Paul: for two channel recordings:For Romy's method to work perfectly, there should be no ambiance in the recording so that he can fill in the room ambiance with his stored reflections program. I don't think how many mikes used would make a difference...

For 25K I'd use 10-15K to acoustic treat the sound room and rest for the speaker......
