I need to know how much volume in litres the Eminence Alpha 6 takes up so I can add that to my final back chamber volume.

Also, their website states an xmax of 0mm, does anyone know how much excursion (linear, one way) I can really get out of it?

I emailed Eminence about a week ago, and no response :-( I hope somebody can help me!

Thanks!
Adrian
