They must've updated the manual. I rechecked the one I downloaded to make sure I hadn't misread it and it says 23Hz (not 24). So maybe that was just a typo & no big deal. I'll go back and get the new version of the OM. Thanks for the heads up on the update eljay.
I'd still like to get the actual HxWxD measurements if anyone has it. Does the grill really stick out 3 inches? 20% of the depth of the sub seems large for a grill. However, if it sounds good at that size I don't think many people will complain about that. I'd also appreciate anyone's opinion on how it sounds in a real room.
I would also like to see a pic of one with this grill. The PB1000 I am going to replace has a cloth grill and the stock photo of the new grill on the PB2000 looks a bit odd/cheap to me for some reason. So if someone gets one I would love to see a pic of it in a room, etc.
