TH,Avoiding mistakes is something that we would like to do. It saves time and money BUT unfortunately the science of building loudspeakers is based on specs, not „Tone“ or „Sound“. Being an engineer can help make beautiful drawings but we all learn t...

hello everybody
I am interrested by manufacturing this type of multicellular horn and I would like to know who you would parmit the worksheet for this type of cab [url=http://www.servimg.com/image_preview.php?i=1172&u=11328848][img]http://i55.ser...

The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). This is not to speak of its FR performance...

How do I hate DIY? Let me count the ways...Is there some reason you cannot make through-holes to facilitate soldering leads to your copper sheet? Use a hot iron (800 F) and plenty of aggressive flux to pre-tin the holes... Stand parts on short leads...

Ham-set,I think you are digging a hole in a wrong place. Regardless of any SiC alleged or actual problems I absolutely assure that the ham you have has absolutely nothing to do with type of the diodes you use but only come from grounding, shielding a...

I did not know that there are any modern V-FET designs. As I understand, the V-FET transistors were available in 1970-1980 and were not produced since there. From what I heard that the DIY people who try to do V-FET amps buy old Sony and Yamaha machi...

LaurentAlthough I have whined that the ML2 requires "tweaking" to get its best, the truth is that it is closer to the dream of acceptable "plug and play" performance than any amp I have ever used. Which is a long preamble to saying I am hardly an ex...

hi mikei heard the avalons at the factory of a manufacturer of wonderful tube amplifiers in italy, http://www.angstromresearch.com/pre_ita.html ( certainly these guys would make big success in the states, if they were able to produce more than 5...

Yes, the laconic clarity is too rare and too worthy to let go. My limited experience suggests that the 45 may have this very special ability, taken alone. Conversely, the "good" 6SN7 is wonderful with respect to tonal...

said that switching of my diodes has a lot of room to be better; could
you elaborate could/should I manage it? Thanks.Romy, I have only a very limited experience with vacuum diodes, not with sand. The kink is a bit worrying.I b...

I would like to share my observations about public perception of Melquiades - The Realty Reconstructions Amplifier.
Melquiades, or as I affectedly-abridgedly call it “the Melq” was released to pubic exactly a year ago:

Yes, it looks not particularly sexy but it I was made to fit and it is for sure very functional. You shall not worry about attractiveness as when I pile up on this thing TT and whatever else will be located on it then it will have completely differen...

Hi Romy, I ended up using a TAD 1101h 11 inch driver, 97db, 38fs, and is what I believe a stronger cone than the Goto 8 inch. The DIY mid bass horn is a 1/2 space 53hz hyperbolic horn with 5in x 5in square throat. Length is about 8'6", height of mout...

There was some kind of hi-fi show in Gernany and it looks like Cessaro showed off a new version of Gamma. They look like change the frame. I really do not like what they look now. They look heavier with new frame and much less elegant. They looks lik...

Silbatone made a Demo with those Horns (the big ones)They said, it is one of three existing WE Horns, made 1935/36 (only mod is the addition of the tweeter you can see there). One Horn is made for 3500 Visitors, so we got a 7000 People Demo with them...

How great it would be if there was some kind of "breakthrough" every so often, in order to make linear "progress" with the driver evaluations and speaker development! In fact, it is almost impossible to keep meaningful "controls" in place between eva...

Again, not to make a "formula", but I was thinking about the possible roles of the speaker in "offsetting" the typical upward-tending tone/harmonics of hi-fi. Sure, there are lots of strategies to "deal with" the upward tendency. These ideas mi...

Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...

hi Romy. Agree, didnt talk too much to him but you can feel having bit of empathy that hes a very warm hearted, relaxed and polite decent personality. Looks like a righteous guy. Also wish him best. Why im still writing this here? I dont think theres...

hi RomyI don’t feel much friction with your response. Thats mostly fine. But I replied assuming such a question is raised by someone who has experienced DIY background and basics how to „design sound“.This is of course a precondition. Of course we ca...

Dear blue,I think that you are reading this site incorrectly.Romy has done an incredible job of documenting his personal audio travels. Consider this site to be a diary in that respect. It has absolutely nothing to do with DIY, except perhaps as moti...

Interesting….. It is interesting to think about the relational of Melquiades slow take-up. I think that major contributing factor is that guy who calls himself Romy the Cat. Really, I think it’s it. The people who are capable to build amplifiers more...
