OK, I have desired to build the thing. It is not the I really need it but I would need some kind MiniMe monitor and I really would like to see how bad it will turn out to sound the speaker that I invasion with this drivers of mine. After much vague c...

1) No, the cabinet is not 10K more. It's 19.5K more... and not even Baltic Birch, but Douglas Fir. Again, with a long justification about the special laquer finish used how expensive it is, how long it takes to apply, etc....

How many times have we heard the mantra, speakers/amps/room? Over the past few months I have listened to many non-musical private and salon installations, amazed that the owners have in every case seemed generally happy with the sound from their exp...

what do you see fundamentally appealing in the symmetry of the differential circuits and what the relations between Sound the symmetry? Not to mention that the perfectly symmetric circuits do not exists. I’m very far form...

Yes, centrally it is the speaker, actual not the speaker themselves but rather the speakers along with the entire reproductive chain. As far as the “speakers that doesn't peak at HF”… my do not, some other do not it as well. However the sufficiency o...

Romy,If you look behind the physical time alignment and start discussion about relative time alignment, that is a good start. Thing puzzle me about your view and comment of GOTO system setup that you have seen on pictures or web. How will you know ...

Hi Romy,Minor question with hopefully a simple answer.In the DSET schematic you have a 12.1k resistor in the bias for channels B, C, D and F. I have some nice 12k resistors here (not 12.1k) that I could use in those positions...can you see a problem...

Hi Romy,So it is time to think about the bass output transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side set in a sealed box and will cover the frequency range below say 100Hz. These drivers can be wired anywhere between 1R an...

Romy notes:[quote]The Lamm ML3 with it’s (looks like) composite driver stage might most likly to pump a lot of current and it would be so rational to put in there a second GM70 on the same chassis with own transformer, driving it from the same driver...

In my case, there are only three 12 gauge wires in each AC cord. I only connect a hot and a "neutral" (circuit ground) at both ends. The "safety ground" wire is "lifted" at the amp (or whatever; it runs short/is not connected to the component-end p...

I listened to those some time ago. It was a full Lamm combo with ML3 + LP2 paired with Wilson Alexandria. This Doc from the WBF Forum never missed a second to tell the world how super this combination is. Above the holy grail. I found an owner with s...

I first heard the WAMMs in LA, sometime around 1984-5, or so. They were multi-amped. I suppose my (SS) amps would drive the new WAMMs FR, since they will easily drive Mark M's giant electrostatic speakers to over 100 dB, measured at 5 m. They are ...

Wow! Did I ever stumble onto the right website.I've got enough reading here for a few lifetimes.Recently I cracked open a couple of speaker cabinets that I obtained years ago. Inside I found a Vitavox AK 121 woofer and a G.P. 1 horn unit, along wit...

Well the whole write up i just wrote disappeared. In one sense that isn't all that different from my experience of the Festival Son et Image here in Montreal yesterday. i'll be quick this time in the hopes that my post will get through. bett-er rooms...

I stopped by yestoday ay NY show for a couple hours. Somewhere in there SRA’s Kevin Tellekamp fished me and told me that he wants to show me something very interesting. He brought me into a room where Hørning loudspeakers were demonstrating. (http://...

I too want a monitor speaker to play with, especially for amplifier experimentation.I put another 4" Fostex in a sealed "box" (globe actually) and crossed it over at 150hz to one SS 25w/8565 on the side. Wishful thinking? -Yes.About 88-90dB sensitive...

A always considered that there are two altimate clowns in audio-press: Srajan Ebaen from 6.moons and Steven Rochlin from enjoy the Music. If I perceive Steven Rochlin as some kind of freakish “Da Ali G” of audio then Srajan stir within me with ...

This is the last article in the planed overview. Here I would like to cover options available among commercially available High-Efficiency systems. As you might expect it will not be too exiting.
In a ways commercial systems inherent all problems of...

[quote user="Romy the Cat"]Twogoodears, What you are experimentation now has yet nothing to do with DPoLS. You deal with the relatively rudimental ceremony of speaker positioning. It is not even close to the subject of DPoLS but it is also greatly ne...

Several years ago I down loaded a print from a site long gone, only to find a modified version of it on Jeff Robinsons site. The print was for a folded horn of manifold sections loaded with a 12" speaker only , and the text is in Hungarian. The print...

The fact is, typical "stereo" L and R separation is mostly an engineering hodge-podge to begin with, and any further messing with it will be very much settled by ear, whether at line or at speaker level. Yet James Bongiorno set out to "solve" the pr...

Yes, that WAS a common connector but this won't help you now. Radio Shack sold those as recently as ten years ago.Since the female side of the connectors has spring terminals there is some variability permitted in the diameter of the male contacts. I...

The idea of a driver/speaker that "sorts out" noise and "puts it in its place" is very interesting! But perhaps we are thinking wrongly about how this might be done? As far as doing it earlier in the "reproduction" chain, I do know a version of thi...

scooter, that was a whole point – to see if the fundamental dilemma of the those designs was addressed. Frankly I was prepared to see some kind of interpretation of unity horn, not just blunt lock of any efforts in this direction. As is, the Vittora...

One funny thing about "dynamic range" is that different audio camps claim to desire and get some form of "improved" "dynamics" from their respective, widely differing topologies, from panels to single drivers, to plasma, etc.Maybe they don't claim to...

hi! Funny... i just passed it in Munich yesterday. Now its mentioned here. Of course i had to stop and have a listen with such cool look. Sorry to tell you, that things a imposter. I left in less than five minutes. It hurts my ears. Totally cold, sha...

Okay, here's a graph that shows theoretically what will happen when the volume is doubled and a few other circumstances. It should give you an idea of what's going on. It is important to note that when the Vb is doubled, th...

For a living, I teach presentation skills to executives and senior managers ( www.youtube.com/watch?v=DJetXp2r3pc ) . I always begin by considering the listeners and what they are looking for. I'll ask people what turns them off when they are in ...

[quote user="Paul S"]The frustrating thing for me while messing with the mounting screw tensions was that there was never a universal "best" setting that involved looseness, but it would all change with different sources or at different volume settin...

Maybe I'm not following novygera but isn't that what electrostatic speakers already do? I mean the full range ones. I thought some of Magnepan's smaller models only had quasi ribbon drivers also. I agree that it is not likely that one type of speaker...
