So what turned me off in the entire Speedysteve project? This is your homework to figure out, the readers.Rgs, Romy the Cat[/quote] I think Romy's just jealous of all those conical horns, as endorsed by "he who shall ...

Romy, Any thoughts yet as to Injection Channel location/integration in new room? Selfish question, I recently got a pair of reds, and have been trying to think of how to place them/type of enclosure to build, without disturbing image, or too much di...

Would YO 186 be appropriate to use in "fundamental" chanel? Over narrower band width, to color, "spice," "flavor" more? --Don't know why I'm even asking, the YO 186 seems to be scarce as hen's teeth, totally unavailable, I'll probably never see any...

Ok; there's a mis-print somewhere, or a manufacturing change... The web site linked listed SG-370 as 23,000 gauss, and SG-370DX as 24,000 gauss. The goto brochure lists SG-370 as 24,000 gauss. And was discussed yesterday w/ someone, one doesn't re...

Have you read Alton Everest's "Master Handbook of Acoustics?" http://www.amazon.com/Master-Handbook-Acoustics-Alton-Everest/dp/0071360972 Not about loudspeakers, but a lot of info about rooms, and interactions. Not a "textbook," but a lot of subjec...

where are you? what are you trying to do? (cnc one pair of horns out of "something," build a mold, build a series of molds for different size horns)? i'm interested in doing the last of the mentioned options, and building molds w/ cnc for differen...

People frequently talk that a higher loading has lower distortions but I do not thing that is has anything to do with distortions. The key in here is that harmonics that are changed with lording – higher loading get “sho...

Yes, tapped horns are lower efficiency, mine are 105 dB (not 108 - 110 dB like the rest of the system). I don't even KNOW that SET or Class A is automatically appropriate for tapped horns... Something like op amp driven PP in class AB might even wo...

on 1) & 2); by "digital experiments" I meant "get a cheap digital crossover and try different slopes; on 3) & 4): Dave Slagle, Intact Audio, knows a LOT more about transformers than I do, and the nickle autoformers I got from him wo...

[quote user="Romy the Cat"]I think it might be very interesting to introduce the high-pass filtration for tapped horn and to see how it behaves. It is not only about thermal overload and restriction of excursion. The unloading of none-used bass gener...

ahh yes, tapped horn is what you would call "close bottom." It has to be designed around frequency response (which is very narrow band). It isn't a problem getting one to go low enough though, and the quality of sub bass produced, smooth yet dy...

I do not know what is meant by “close bottom” or “open bottomless”-- please expound?I do not know of importance of enemys death to this topic. There is a long thread in the subwoofer section of "devil audio" about tapped horns. John mentioned gettin...

I built a pair of tapped horns, as per John Hasquin, designed to integrate w/ mid-bass horns (cross over ~ 70-80 hz). Loaded in the corners, the low bass is well supported, and, they "dissapear" sonicaly. By that, I mean, they don't "stick out" at ...

...no sarcasm was meant, nothing to "read between the lines." Several people seemed quite impressed w/ 138s in DIYaudio thread early on, said no tweeter ever needed, best mids they ever heard in anything, etc. That was part of what prompt...
|
|
KM, I don't know how you come up with the belief that I conclude that "it's a bad performing driver." Either the 138, or the earlier 120... Or that because I didn't use 120s that i haven't heard them. And as ever...

Good luck getting midrange from F120A for non annoying monitors. Seems reasonable to expect, many people have been very happy with these drivers... I haven't tried this specific driver, but have spent some time trying to get a simila...

the famous, in-depth cap review on: http://www.humblehomemadehifi.com/Cap.html For electrolytics, i like solen fast caps, cheap, small. I'd much prefer an oil cap, like the ASC 386s, (available on ebay inexpensively as motor runs). B...

I didn't say "it's impossible." I'm saying "I don't know a format that would be functional @ this time." Gotta work now; will try to condense into something more resembling one page of notes for resistors or something & po...

Thanx Romy,
Yes, fitting "time produced" into the matrix is an important piece of the puzzle, don't think I mentioned that one.
Holco resistors are a great example, are in my notes, along with other resistors, and caps, that have changed.&n...
