I'm a sucker for a good deal, so I did a thing: https://www.monoprice.com/product?p_id=9723 I ordered a Monoprice 12" 150w subwoofer, on sale for $75, and $65 after BONUS10 code. $17.61/2 weeks with Paypal Pay-In-4. Specs say it goes down to 20Hz. (see link for dB chart) Going to set the xover at 60Hz and just let it handle the low end. My neighbors are going to hate me.
