I have always found the concept of a cylinder sub, tall with a small footprint to be an appealing one. I was wondering if there has been any thought given to developing such versions of the Rythmik subs? Are there any reasons why this would be a bad idea from a performance standpoint? Most such designs I am aware of are ported, but I wonder if there are any reasons one couldn't do a sealed sub this way as well?

Thanks,

Chris
