I was able to get a Polk MM1240 subwoofer (single voice coil) real cheap. I have a spare Dayton Audio 250-watt plate amplifier which I am not really using. I was thinking of building a HT subwoofer with the driver.
Question is whether I should build a vented or sealed system. After punching the TS parameters, it appears the sub is somewhat designed for a sealed cabinet. Does anyone have any opinions or experience with this driver?
