The three port design reminds me of the PB13 Ultra.
Just curious, is there any benefit from having three separate ports over one larger single port?
I understand you could plug a port, or two ports in this case, and this will adjust the tuning aspects and frequency response of the sub. Is that the only benefit? Aside from aesthetics?
Personally I think 3 ports across the front looks pretty hawt. Sorry to my FV15's!
