Sundown Audio M-12 D1

The Sundown M-Series is an all-new "entry-level" subwoofer in Mega series - all Mega series subwoofers (10,12,15,18) feature custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841) and Mega-Roll surround. For the M-series, Sundown mate out Mega series frames to a quad stacked 200mm (7.87”) diameter motor structure with a total magnet stack height of 88mm (3.46”) featuring a hyper-extended pole and extreme clearances (allowing 59.5mm to mechanical bottom effectively making it bottomless - this is 4.68" peak-to-peak). Sundown always do things to the extreme so even "entry" level M-series features a full 20mm thick top-plate to finish the efficient magnetic circuit.

Awesome sub!!

This subwoofer is an absolute beast! Build quality is top notch. I got it as an open box deal, which i would highly recommend. Saved me almost $200. The sound quality is amazing! It's rated for 2000w rms, I'm running an alpine amp that only pushes 900w rms, and it's still loud AF. Bass is loud, deep, and clean. Sundown has a new customer fore life!
