#126 Klipsch Reference R-120SW: $329.00 each Amazon eBay
Pros: A high-volume budget 12-inch powered home theater subwoofer with 200W RMS / 400W peak all-digital amplification. Features a 12-inch front-firing spun-copper IMG woofer and a rear-firing Tractrix port that maximizes air transfer and minimizes port noise. Delivers visceral, energetic low-end slam down to 29Hz at an accessible price point, making it a staple recommendation for entry-level 5.1 surround sound and gaming setups.
Cons: The ported enclosure begins rolling off sharply below 28Hz, lacking the true 20Hz infrasonic output of Reference Premiere models. Rear port placement requires pulling the cabinet at least 6 to 12 inches away from room walls to avoid boomy port turbulence.
How it compares: Just above it: MartinLogan Dynamo 600X - $219 more. Just below it: Klipsch R-12SW - $50 cheaper.
