putting an ESL in a box

[Borat]

blasphemy i know, but anyway

i think ML CLX is probably a perfect tranducer. but that's all it is - a tranducer. i wouldn't call it a speaker because it still needs bass.

problem is it's going to take up half a room by itself and there is simply not going to be any space left for a bass tower as in statements.

if i had a mansion i would just build a DIY sub to combine with CLX for an improvide statement speaker but i am too poor for that.

so i was thinking of how the whole setup can be made compact enough to fit into an average living room. there seems to be only one way. you have to enclose the back of the ESL and screw a flat subwoofer cabinet to the back of that.

so the whole speaker would be about 2 feet deep. the first foot would be the enclosure for ESL ( with a few thousand dollars worth of damping material in there ) and the second foot would be a subwoofer enclosure comprised of multiple sealed compartments each for lets say a 12" driver.

of course the curved and flat sections of ESL would have separate enclosing volumes. the one for flat section much larger than one for curved one.

what do you say to that ?

after all STAX has closed headphones ...

the reason i wouldn't just put a bass tower behind an open CLX is because the bass would go through the panel causing it to max out on excursion before it even started playing. the enclosing volume would be primarily to limit ESL excursion due to the adjacent subwoofers.

in fact would make more sense to use another speaker from ML a hybrid one, and just throw away the bass section in the trash.

would be more compact then.

Hi Borat,

Have you listened to the closed STAX headphones?

I have, and I prefer mine to be open. Why? Because the sound is more open and transparent. It's just more real. I think most of the people who build ESL like the fact that they are dipole, and the sound stage is just different from what you can get from the boxed speakers. But of course, you might prefer differently. And the only way to find out is to try it.

Stax, closed?
Mines are open!
So are all models I've recently seen in the magazines.
If you move your hands towards the stax headphone you will notice that sound changes. This is because your hands reflects the sound and the reflected sound just goes right through the stax back to your ears. It sounds like a colouration, no trouble in hearing the difference.
Nice experiment to try yourself. You will be amazed how far your hands must be away from the stax without having colouration.

If you think of it as a tranduser what is the fs and VAS ? I would guess if you
put it in a closed box any reasonable size say 8 cubic feet or less you would push
the fs way way up with a realy high qts. So you would have one heck of a peak
at fs the speaker would be rooling off at a much higher frequency.

I'm sorry. The closed ES headphones which I have listened to was Koss. They are oldies but goodies.

wrong.

they would go deeper due to less out of phase cancellation and there would not be any peak because i would use an appropriate damping strategy.

Hi drs M.J. Dijkstra

maybe you look here:
stax4070.html
There should be the closed STAX.
This is the studio version.

I beleve what you mentioned,
and as you can read that STAX
only have this version for the professional use,
because there it is needed to be closed.

point is:

1 - it can be done

2 - sometimes you need to do it

Yes, as I wrote in the studios they need to have it like this.
But they do not do it because it is better -
it is an exeption for this case.
