Reply To: RE: Tang Band W5-1138SMF 5-1/4" Subwoofer – Specs all over the place?

[ttan98]

Hi,

I built a subwoofer based on this woofer W5-1138SMF, Put into an existing cabinet is about 7.0litres, and the port diameter is 2″ dia and 4″ length flare both ends. I seem to get chuffing at a higher level.

1. Is the port dimensions adequate or need to be longer?

2. DO I need to improve Internal reinforcement to improve the Bass response?

 

thanks.
