Brother it would be a find by luck. There are few facebook pages dealing in such subwoofers of these kind. But these are used items and mostly are repaired as these are mostly sold as scrap or usually come in lot. Also there is no guarantee they would last a week or a year. I would recommend you to get a base tube and 4 channel amplifier if you are really a fan of base . Else a good pair of components can do the job pretty well
