Hi mapman,
The room is not bad at all. I have no real problems in the bass department really. Plenty of deep, tuneful, controlled bass with a kind of air about it with lots of texture.
The Virtual dynamics cables are the finest I have heard for this. It seems to make up for some sensitivity in the speaker and lets the amps grip the drivers.
I had subs before, but I was hardly using them so I sold them. It was great for movies though! Silly deep bass but fun. Not much use for music. Remember the Apogee goes down to 30hz on its own. The subs went to 10hz.
There is nothing down there though. If you look at the music through spectrum monitor you will see nothing near 30.
Well maybe I will send you a file of 24bit 192khz. Your problem will be reading it and decoding it. As I said to Florian if he wants to hear it I will have my studio computer with me anyway, so it wont be a problem.
