Forgot to mention that the speaker contains 3 ports on the back, please click the "further details" link on the previous web page link address to check for the speakers construction.
Do you still think it would be enough?!
Should I make it thicker? In fact I was thinking in making it a little wider...
I did try to put the panels just in place 60x135 on the floor level, didn't do any measurements but I really liked what I eard!
Thanks a lot!
