Romy,
It's good to have all this info in one post.
Regarding N° 5 :
"5) Horns shell have a sufficient mass properly projected to a given channel’s LF boundary and the horn’s mass should be properly distributed within a horn."
I have seen a lo...

[quote user="jessie.dazzle"] This event really reinforces my curiosity to try such drivers in the Mid-Bass horns. As there are plenty here in Europe, that is exactly my plan (most however are not 16O... don't know to what extent that might be an issu...

INTEGRATION that's the clue and that's what I always feel lacks in my room, I mean extreme integration, real integration, the feeling that the recorded bass sound has its own boundaries, not my room's. So you said, midbass horns?OK, let's g...

I bought those tweeters for Be Yamamura (second hand from Paul at Wembly Loudspeakers, in London) I also took Be to Heathrow Airport to take a plane to Brazil to install one of his truly superb VT4c stereo amps! It was the morning of a great wind ...

Ronnie,
Arranging the driver in a line array is a fierily straight forward thing. Also be advised that the arrays will less likely work across a short wall, and you need to use a long wall. Generally it is imposable to advise anything as any rooms a...

.... available bass horns are the same to me and I customary discard them. I also care less about the price: I am talking about an interesting horn design but not about an interesting product to buy. The beryllium cones - yes I do not like them in TA...

Hi,I thought on tetrodo (KT-88, KT-120, KT150) and write pentodo, sorry. Wherever the tetrodo sound were nothing special I personally find them a lot of better than solid state, that why I was asking, and these days one can have 300W with to KT150 P...

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear...

Have you tried taking a measurement with the line arrays moved to the rear of the room? (ideally, the same as the current distance from the listening point, but behind you).If you can do this, and if the result is a more gentle curve, consider bass e...

I had a similar setup with an IB subwoofer, 2x18" woofers, behind the listening area -- also time aligned. It's works ok. But it will excite the entire house structure if you play loud -- you can be sure. Everyone will feel it. But that's not the iss...

I never heard the Vacuumstate. A pair of 300B in the “differential SET” application… Hm, would it sound different then a regular 300B? Juts kidding… The last “SET tandem” that I head was with a pair of 6C33C in “differential SET” pushing 45W. The amp...

Romy, whether intentionally or otherwise, "murky waters" is a beautiful metaphor for the Western Electric route, in my experience; that said, just because something does not exist, does not mean that I might not be made so with a less hidebound a...

[quote user="Romy the Cat"]I do not understand what does it mean. Are you saying

Here's how I will initially position the mid bass horns. The imaging is excellent....though I give a little away in dynamics. The 12-inch B&C drivers kill the puny 8-inch Fane drivers for this application. Well done John Inlow for this design. I ...

Oddly the seller has removed the images of the wood horns as well as the mid bass compression drivers. They are still illustrated in the plans. Great looking horns. Perhaps he sold them. They where 150 to 5k drivers. I think Jeffery Jackson probably ...

I confess that at one point I tried PM6As in 2.5 cu. ft. vented boxes. Lousy, tipped-up balance and soggy, one-note "bass", contrary to the designer's claims. The only thing good about it was that the box did not add c...
