3D stereo sound with 4 speakers + room correction

Hi all,
I´m Johnny - a long time reader of Audiogon, hifi geek and music producer from Denmark - and I have a "different" question to all of you Audiogoner´s out there.
Have anyone tried to do a stereo system - but with 4 speakers and room correction + time alignment? Fx 4 (same) speakers to 4 monoblocks or 2 power amps from a preamp + room correction. Maybe you´ve just tried with 4 speakers and no room correction - anyways - let me hear your experiences.
I´m thinking of - sometime in the future - if funds and space allows it - to do a system like that. I would put 2 speakers as fronts and 2 speakers as side speakers. I imagine that the room correction and time alignment would make it possible to achieve a 3D stereo sound that reaches your sweetspot at the same time - but still in stereo. The sound stage would be almost all around you and massive.
Is this completely nonsense or would it make sense to do a system like this?
Ps. If I had the money - I´m thinking - Soundlab U1 speakers + 2 or 4 JL Audio f113 subwoofers and some great amplification + source. We don´t have Soundlab speakers here in Denmark so I have yet to discover the sound of them - though I have heard both the biggest Magnepans and Martin Logans - and several other high end speakers incl. MBL (the big ones) Adam (reference setup) Avantgarde (the big system). My own speaker are Audio Physic Scorpio - and I´m actually very pleased with them and I will keep them for a while.
Please let me know your thoughts on my question.
ps. and thanks for letting me dream away in the member systems pages :-)

Hi Johnny

The idea is interesting and time alignment will be important. How do you plan on achieving the room correction part to the sound?

I almost think you are talking about crosstalk cancellation to achieve room correction?

Just trying to see where we are going with the idea thats all, its very interesting to me as I always thought to achieve the concert hall sound it would require one to start with two pairs of identical speakers but never experimented with this theory.

Hi Johhny. Does the TACT allow you to connect four amps & speakers in the manner you are talking about? I would think all four speakers would need to be facing you to be in alignment with each other and your sitting position. It would be an interesting experiment but will cost a few $ to pull off if you want to use identical high end amps & speakers. Also bass response is an issue. Four speakers in the same room may actually cause bass waves to cancel each other leaving a thinner bottom end. I would seem to think the processor you choose will need to try & correct so many room & audio anomalies that the music recorded and mixed to two channel will become very artificial sounding.
