Just wondering if there is any difference, sound or otherwise between the horizontal and vertical 600 sub?
Thanks

Not supposed to be. I have the vertical and asked this question whenever I made the purchase and was told that no, sonically there is not any difference. Other than maybe a couple of folks (Alan & Amie) who have the 'H' model I think most everyone has the 'V' or vertical model....and that thing sure stands tall!

Mike - There really isn't any difference. We have both, it is just a matter of which fits better into your room.
