Then I have an older xtant A 10" svc 2 ohm sub. Not bad sub at all. Basically this is an Mtx Blue Thunder with cosmetic differences. and very versatile as far as enclosures.

$65 shipped.

Sealed, ported, bandpass anything...very small enclosures is all I remember. Data is out there.

Again, tons of refs if you search the name here on diyma. Im an adult with a career, this is just a hobby/addiction for me and just wanna do financial harm reduction.
