Hi Romy:as I don't consider the thread as emptied, yet, I'd wish to add some thoughts after more days of listening to my system.I re-read an half-page chapter in French from Jean Hiraga's "Les Hautparleur" essay, concerning time-alignement and p...

Hey guy, syop your bullshit just for once.Ok this thread was not appropriate...fine.If i come here -at first- it was not to ask for advices, it was a case of emergency (sorry to everyone if it has bothered you).Now i've come here to discuss about sou...

Hi all,In my experience it is VERY hard to get anything resembling realistic bass from a vented box, particularly with a Q of around 0.9 or 1. There is too much stored energy in the system and too much overhang. The best bass I have heard...

The weak bass of low-power SET amps is well known. I don't think anyone would disagree.Some reasons:Simple low power, especially with 93db speakers (try with 106db like Yorkville LS1208 horn subwoofer it might be different).SE output transformers hav...

Mani at al. I have a paid of zu druids. Running them with 15W amp (d-class) and it is not enough for high level, although it does better than you expect. The soundstage sensitivity measurement was 97dB, but their test did not load the driver correctl...

But one needs the right tool for the right job. I don't think Milq could teach me what I need to learn using my current speakers, in spite I've driven them with low power SETs with acceptable (just sound-wise) results.[quote user="Romy the Cat"]...Th...

[quote user="HookEm"]OK, would you say the weak link would then be:1) Just the topology of Lamhorn (single driver with back-loaded horn appendix)2) Any single driver back-loaded loudspeaker in general3) Or any single driver loudspeaker in generalOr p...

Thanks, Scooter.I am glad to hear from someone so quickly.I've been an "audiophile" for only 10 years or so. With the Edgarhorns, I am currently using a Cyrus Brenneman integrated amp (KT100). I also have a Yamamoto custom 2A3 (single plates) w...

[quote user="Romy the Cat"]Can you post or explain the topology of your 6SN7-2A3?[/quote]The amplifiers I use started from a kit I bought, the Moondog, so here you can see the basic topology. It is very simple. The first stage here can be eliminated,...

[quote user="Wojtek"]I plan to attach tweeter in a place of the lense to bellows (I hope thats correct term) used in macro -photograpfhy .They look sturdy enough and should provide 10cm of fine ,easy adjustment and I can buy them cheap ($10) on any p...

Thanks for alternate driver idea, Romy. Sounds interesting.I certainly do not need all the gain from the ML2 along with my AI M3A phono/pre-amp, so I will give the 5687 family a try once I figure out a decent, fool proof pin-out adapt...

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 ...

Thank you Romy,
<<The multiamping with Super Melquiades was made with intend to optimize the output transformers and to eliminate the interference between the inductance of the upper bass driver’s coil and the MF driver. I still use the speake...

In the past month I have been playing around with a sub-woofer. This is my first experience with a sub. Prior to this, I held a bias that subs generally cause more problems than they solve. I am using a sub now because the main horn...

[quote user="CO"] Ive conducted some test with the smaller drivers because i wanted to know if i could build a compact high quality setup to replace my current fairly large speakers. It doesnt look possible though, mainly because (as you say )the Upp...

[quote user="Purite Audio"]The veneering is top quality, did you hear them Stitch?Keith.[/quote]Yes, the quality of making is top but to be fair to other manufacturers, they do a good job also. I think, the finish is more important than the sound qua...

I care less about Bret and his business, in fact I have no idea who is he. Since he use audio as business then what distinct him from any other audio whore. A purpose of any business is supply demands and capitalize on the frustrations, investin...

I really enjoy this site. Romy has a fresh view that is actually easy to understand, if one simply reads instead of interpreting what he writes.Still, a view from "higher up" is something that many of us are not privileged to. Looking at the major co...

[quote user="Paul S"]"High-efficiency electrostatic speakers"??? Is this not an oxymoron? My friend, Mark, who sometimes visits and posts in this form, has gigantic Sound Lab 'stats. He hates SS, and he uses VTL Wotan tube amps to drive them, 1.200W ...

John Sheerin? I have come across what this character does on-line. I am not familiar with him personally but I am NOT a big fun of what he does. He moves his hands in space and sometimes as the resume of his hands moment some horn are built up. H...

[quote]That is a bold waste of
speaker’s surface for a small result.[/quote]Yeah, but plywood is cheap and the result is audibly noticeable. Baffle extensions were recommended for all of the Altec VOT cabinets too. Make a big improvement for cheap ...

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...

I have used thick wool felt around the perimeter of my round horns at times. Having owned a pair of ROGERS LS3/5a's in my youth and being amazed at the huge sound those little speakers could effect one tries to re-use ideas. Diffraction control is ...

[quote user="perrew"] ….. is there any chance of a speaker/horn of this type sounding good compared to a conventional monitor… [/quote] Perrew, there is absolutely no reasons or any imaginary rational in this type of speaker to use horns besides to m...

Romy, I was delighted to see your video monologue, and I look forward to following along your new journey.No speaker can reproduce the reality of a live musical event for various reasons, and all speakers are by their nature a conglomeration of engin...

For my ears, the piano is rich in harmonics that change with playing volume BUT the only way to get a louder note is with the hammer striking the strings more powerfully which always is coupled to a louder "articulation". Violins and wind instruments...

Working with (not against) material resonance would be an interesting alternative way but I would predict a long and strenuous path... Imagine yourself having to tune not (only) the strings of a cello but the instrument itself. :-D

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...
