Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

Fllowing my experiments with Injection Channel

I have discovered recently that I was a greedy fool who should know better.
The new Injection Channel does OK as a independent single channel bu...

[quote user="haralanov"] Some time ago I intentionally made two different boxes for my ScanSpeak drivers to see what will happen, because I do not believe in theories and trust only to my ears. The boxes had exactly the same internal volume and front...

Well, the points you bring up are valid but as anything else it all highlight problems with people not with equipment. I am not sure that I am glad with my decisiveness and sanity in MiniMe projects. I was trying to rationalize the MiniMe idea in the...

I had recently a guy in my listening room and he asked me if it would be possible to get the 300Hz range in the way how it sounds in my room but without using those larger uppe...

[quote user="MusicLover"] Higher even order distortion sounds richer and makes the sound "more live" to most people. YOu can get that anywhere in the signal chain. [/quote]

Chris, I did ask myself the same question: perhaps my given PTR9 is demagnetized. I called the last night to the owner of the tweeters and he said that he uses them for 7 years and they driver should be fine. He also expressed a lot of doubts if the ...

I was sit today to do the calibration of my infinite baffle.
I connected my 20Hz 4th order tube crossover with frond-end modified
Yamaha B-2. The RTA did show a very easy gain exactly where should be, the
transition slope doe the magic. I rolled ...

Not without interest read I the article at the sewer about
the Rullit Aero-8 driver. http://www.audioasylum.com/forums/hug/messages/17/170078.html
It does sounds like a reasonable driver at least from a perspective
of opened baff...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

"Gargoyle, YMMV, but I
associate LF propagation/amplification with mass; there has to be some
way to really "anchor" at least the LF driver. "Noted"I was thinking MF for

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

I also see this project to enhance a value of property. If I place in the mouth of my midbass horn some kind of MF/FM driver then I will be able to presen...

I was listening last night a string quartet rehearsal. The play was for the most part justifiably non-so-glorious and I was thinking about my little audio things. For sure our upper MF drivers nowhere near where they need to be. There is too much...

I am quite fascinated with the result that I might get from MiniME and at the same time I am defensive with the direction it takes. Anyhow, here is how it stands…
The decision to go for MF driver was I think right one. Even the 70-20RX tweeter has s...
