I agree with the above. If you really want to tinker, buy a sealed enclosure raw driver and build an enclosure yourself. That would be the best way to go.
Permanently sealing a vented subwoofer??
I have a budget subwoofer that I would like to tinker with if the results are positive. I read that to some degree, sealed subwoofers can produce much better in a music based system than a vented subwoofer. What would be the results if I permanently sealed the vent on a vented subwoofer? What are the consequences? Is this possible?
