my flush\inwall\ib system

Flaesh · 25th September 2010, 04:35 PM

HF - Radian 950pb in ph2380 horns.
LF - 18sound 15nd730 in IB.
X-over and equalisation - DCX2496.
+transport, amplifiers, cables, two holes in the wall, a few pieces of chipboard - it's all for now.
Perhaps, it will be 3- or 4-way

sometime later.
Now it works fine enough in this simple form

.
I'll add measurements soon.

How does the backside sound flaesh.

Flaesh · 21st November 2010, 10:39 AM

backside isn't listenable

it's up to ~555-666hz mainly

Flaesh · 21st November 2010, 11:01 AM

I'm thinking about wall mooving..

I like 'will be?'

I think 'or?' might be too far apart to achieve good imaging other than at the sweet spot. 4m is a long ways apart. Just my 2 pennies.

I'm thinking "OR": with the speakers positioned as per first pix and the subs on the wing wall, with suitable delay of course

Talk about the separation of sources....

Since there's so much freedom in designing a new system in such a room, please consider trying this very interesting concept:

Virtual Acoustics and Audio Engineering: Optimal Source Distribution

Or, this paper also showed similar things:

I just heard about this recently (from a kind person). A very 'revolutionary' setup for DIYers, at least a pretty big WOW to me. In fact I'm not fully recovered yet after that shock...

If the room is still nearly empty and nothing is deadly fixed yet, why not try something very 'different'?

I envy anyone who has the space and freedom to do such experiments.

I haven't had any chance to listen to that kind of arrangement, yet. But I believe the potential.

OK, now he himself starts a new thread here: LQ & OSD: an acoustic alternative

I second Cal Weldon.

And also because you use CD-horn they sound the brightest when they are straight pointed at the listener or only with a very small angle.

You could mount the speaker on a verical axes so you can twist it a bit in wall.

Only your closedbox becomes much smaller Flaesh
