[quote user="rowuk"]Oleg has a lot of bad press in Germany for unkept promises and defaulting on delivery of product. Just keep an open mind next to the open ear. The best product only serves a purpose if it a) arrives and b) performs.I really like t...

Actually it is very possible that it might be so. I made some rudimental measurements and concluded that RAAL tweeter and JBL midrange mounted in the same baffle has non-perfect time aliment. So, I will need to use gaskets under the drivers to time-a...

[quote user="anthony"]This is excellent
information Romy. I have been worried about crossing the woofers at 100Hz
and would be much happier if I was able to cross them lower. We will see
how everything integrates into the room and if I do need t...

[quote user="Wojtek"]but I attached a double layer of 3'x5' cement boards (wonder board) under the suspended floor (crawl space) and it seems to help with bass a little. It's a cheap and fairly easy solution ($9 for a board) if you have an acces ...

[quote user="Romy the Cat"] I bought a few Linn Records own recordings of Duisburg Philharmonic Orchestra, Scottish Chamber Orchestra and Dunedin Consort. They pushed them as “Studio Master” but they are WMA files – means the re-rendered compress...

[quote user="Romy the Cat"] Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that begin to roll somewhere around 800Hz. The transformer ha s a lot of core mass and at full Melquiades’ LF power (~20W) it begins to clip ...

OK, MiniMe now is up and running. It does what it does and I wonder if it can do better then what it does. The LF sections need to have ports fine-tuned but I do not particularly care about bass now. What I do care is MiniMe to have a certain quality...

I had today a long listening session. I listened a whole Mahler Second and I can tell you that I was the best upperbass I ever heard from a playback. I am not kidding. The upperbass literally despaired in the new room but what it is being called up...

Yes, if you are at 40Hz first order then you are with regular dedicated LF channel and tone is certainly a subject. The entire definition of ULF channel inkstand or LF channel is that ULF channel has no tonal information. It is very same like use twe...

A site visitor pointed me out the I never made an intended write up about the David Haigner horns. I just forgot about them… OK, let analyze David’s claims and his Alphahorn design. I would say right the way that I do not like the Alphahorn’s id...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

But here it is. I made this monoblock fit into less than a square foot. It is tight. I use Hammond iron throughout. Their stuff usually works pretty good for power supplies. I have some photos at my blog. [img]http...

Thank you Romy, that was very informative and instructive!I don't completely agree that OP is absolutely irrelevant for linearity.It can happen that some regions, under given design constraints, will not give "a proposer harmonic structure of

Greg, I see a regions of concerns that you might contemplate.
TAD 1201 might be good driver but how useable would be the 200/300-800/1000 range? Let pretend that you end up with 250Hz, then what next? You will introduce a bottom octave section but t...

[quote user="serenechaos"] on 3) & 4): Dave Slagle, Intact Audio, knows a LOT more about transformers than I do, and the nickle autoformers I got from him work so well, I totally trust his (and/or Jeffrey Jackson's) judgment to over my "guess...

[quote user="drdna"]I find the sound of my horn loudspeakers very satisfying, and by the way I have the EdgarHorn Titans, which may make you chuckle if you are a horn snob, but I think they do a very good job, one of the best commercially available h...

Hi, Global.
Leaving aside the unnecessary to be called notion of Melquiades vs. Lamm I would return to the essence of the thread: what changes are necessary in schematic if it goes for 220V. I do not think that any changes would be necessary. All tr...

I wrote about it before and I was/am afraid this effect too. I discovered it a few years back when suddenly my bass picked some odd harmonics. After a few days I realized that the harmonics came from an acoustic guitar that was sitting in my list...

[quote user="op.9"]A 20w tripath and a 5w El84 set per channel is a sensible and cheap combination. The tripath and line level crossover section could be thrown in for free![/quote]

Guy,I absolutely disagree and I think there is a huge difference between lettings your wife to know that skin in her neck remind you sesame chicken and letting a play director know that his new production stinks. Of course we moderate our behavior in...

Thanks, miab
I am encouraged that your guys feel that it is doable. I was cowling in the attic and had very bad feeling. The beams (you call them trusses) are VERY thick and the attic is not a full waking. The house has center AC and my red tr...
