that 8th order X/O works best with them and I cross at 90Hz these days.
4th order is ok but you get minor colourations and some bleed through
that just aren't a distraction on 8th order. ...

Here is where I stay with my enigmatic Remedios project. I build inside of top box at resonator that I tuned 50-60 hertz. So basically it is under two square foot enclosure with a port tune at the bottom of resonance frequency. The port is shooting ...

... to pass data unchanged.I've been ripping my CDs (using EAC and a Plextor CD-ROM drive) for about 4 years now. I use Foobar with ASIO (and now with WASAPI also) as the software player, loaded onto a Sony laptop. The soundcard is an RME FF800.Now t...

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

Bill, the result you or anybody else gets with resonating surface of the horn if NOT what I was talking about. You and Jessie recognized in what I was saying some specific problems of your horn but those problem are from very different reason. The t...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

Yep, you re right, the Yamamoto A-06S is SET, I did not read it carefully and I was under presumption that A-06S is PP monoblock. Good for Yamamoto! The only amps I heard with AD1 were PP. Somewhere in the very end 90s I shortly was exposed to i...

Hi, WojtekI get lots of PM from readers of this site; it should work. Try again, and be careful with the spelling, etc. Though I can easily upload pictures to GSC Image Gallery, I can't seem to get them from the Gallery to the Board. Perhaps they ...

Paul -- I used 1st order & bandpass on the Beyma. I think that 2nd on the Lowther would have been better.I set out to try and extend one "way" from the end of a wide-range drive unit, downwards. This I found to be well nigh impossible -- perhaps ...

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...

Thanks for the advice Romy.But actually, I may not need new tweeters after all (for the time being, at least, until the dreaded 'Autumn Sound' arrives).You see, when I connected them up, I didn't really think too carefully about the speaker...
|
N-set, you may remember that from the beginning I encouraged you to try a wall mount, for all the reasons you have just cited, and this approach seems even more obvious if the walls are concrete/masonry vs. floor joists and sheet subflooring, not to ...

Sorry for posting a bit of kindergarten trivialities but maybe someone without a dedicated line yet will find it motivating.I've finally connected my dedicated lines which took me ages. The lines are connected right behind the power meterand have the...

Ok, I completely disassembled one of the Super Milqs and physically injected extra 3 channels. It looks like everything is all right real-estate wise, still I would prefer of course to have more space….
As now the amp is completely shattered ...

This thread has been pretty interesting overall. I've read most of it and would at least like to provide some feedback on the technical side of designing with the 45 and 2A3 DHTs... at least from my personal experience. A few years back I decid...

Angelo, I do not think this site add anything applied to the subject. I personally do not feel that upper bass horns require any phase plugs; quite in contrary they are dreadful for upper bass horns. When a straight horn employed then the horn does n...

Antonio,Works just fine with ported, unported or open baffle. The process works on the boundary layer of the cone. This is the very thin area between cone material and air. The actual mechanism just disallows energy trapped in this zone from reflecti...

A few years ago somebody, I think it was “drdna” from California, told that he has a habit to listen the mechanical noise of the tube hold the tube at his ear by hitting the balloon of the tube. I did not exactly acknowledge it at that time as it was...

Hi Roman... you know "... but Twogoodears normally prefer a do not go to depth..." it's not an hide & seek kind-of-thing, but a necessity;-), as I'm not technical inclined or taught enough to discuss in depth of circuits designing... I'm only a u...

Paul, 100% agreed on the real world test vs all other mental exercises!!!Not sure on what do you mean by the "follower"?Yes, I need only 2 stages, perhaps TVC at the input. I'll even have a bit too much gain, if I'm correct.Romy style bias on 6E5P an...

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...
|
It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. They already had splurged for...

[quote user="skushino"] Romy, I now see you were asking a totally different question. [/quote]Disconnect tweeter and woofer and connect juts MF channel with 3uF and upperbass channel with whatever low pass you wiling to use. Listen music on thi...

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...

It is very self-explanatory and liked it a lot. The advantage is that it might be used in any rectangular room and the most important that it is VERY simple to build this way. I think that if I have room then I might sto...

This is our first offering; we are indeed working on another two higher priced models. One will have an additional channel on top, the other one will be front horn loaded down to 40 hz. Optional finish and colors, both for horns and supports, a...

[quote user="haralanov"]…. acoustic filter does not rotate electrical phase of the signal. [/quote] I do not think it is correct. The rotation of electrical phase is not the subject of filtration method but subject of slop and Q. Of you write the sam...

Thanks The CatI'm posting the pics of the build as I progress so people can see and pass on ideas, that's all. Are you suggesting you don't want horn projects shown on your site? I had earlier outlined the design, including cross-over points etc.I as...

[quote user="Romy the Cat"] I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Bas...
