[quote user="Romy the Cat"]I am not sure what you are asking. If you willing to get 400Hz horn into 1” tractrix then it might not be any controversy about the horn’s length, it is already given and the folks from lab.de will know it and will do the r...

I spoke this morning with Yoshi and he made a phenomenal comment. He was complaining something about his bass. He uses a pair of big 15’ JBL in a box with an active second order crossover. So, when I asked him to describe what he feels is wrong Yoshi...

I realised this morning that I have done a "not-so-standard" thing in using leftover fibreglass batts for stuffing the tubes. The batts that I have on hand are high density batts, not the low density type of fibreglass that is usually used for stuff...

Thanks for posting the Vandersteen interview.It inspired me to try once more to tame my TAD 1601sthat reside in sealed 3cuft boxes. It worked, but the numbersare slightly shocking. 12mH translates to 100Hz, and 25 uFon 4 Ohm Altec 290’s in 260 Hz hor...

I do not want to go on tangent in this Cessaro Gammas thread, still what Merlin said deserves very much to be accented. I juts mention it once in here.
The first order on the bass units is NOT an “unacceptable compromise”. If your bass section, the ...

hm..lots of interesting information to chew on, and by and large, i've had similar experiences with first order crossovers on bass drivers .. this being my experience with a full range amp, and a two way system-- which is a far different critter than...

Stuck,
You can NOT stack coils in series to get a “distributed half order crossover”. To make it “distributed” the first and the second first-order filters should be decupled. For instance the first filter might be at line-level and the second at th...

Ahm, I thought, that the midrange horn loses its directivity after 7000 and thats there I need the h-105. By the way its the only ring radiator from Coral. How can I add at the same time a first order 10k and 5k to the same driver? I always thought t...

Public - now that is broad. The Public wants easy; not perfect. I would offer a simple two way: 12" paper cones LF with first order low pass [not a horn]. Iwata or Yuichi radial hyperbolic [MF & HF] horn above with first order medium-high ...

Romy,Interesting video. The first thing that came to my mind when you were talking about HF colours and the "clean" RAAL Waterdrop tweeter, is perhaps adding colour to the RAAL. Instead of blanding out the midrange S2 and injecting HF colour with t...

A second opinion needed.
Interesting, I recently found a very-very well performing setting for my EV T350 tweeter. I changed the source for HF channel form amplifier’s output to the MF channel and now I source the HF channel AFTER the MF high-pass f...

Got the ultra low DCR toroids coil and pit them in use. Yes, it was very right move and they a bit trimmed the midbass tail. Playing with inductance and listening how the midbass decays (measurements are worthless in this case) I ended up with 4.8mH ...
