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...

[quote user="coops"]Just a quick note ,I went over to Germany and listened to a pair of Cessaro Alpha's at the home of TW Acoustic's Thomas Woschnick, I thought them absolutely superb, far more 'real' than any other speaker I have heard, ( impossible...

[quote user="drdna"]The idea of 360 degree radiation of sound has great intuitive appeal to me since I feel the best recordings are done with two omnidirectional microphones. The most precise reproduction of the musical event would seem to be: ...

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...

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...

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...

Romy,In response to your response to what I did not say but implied....I decided to put the question here instead, where the light of enquirey might shine upon several different facets of investigation.Firstly, I'm still interested to know if you are...

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...

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 ...

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...

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...

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...

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...

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...

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...
