Brand: Jamo

#189 Jamo C 912 SUB: $599 Discontinued eBay

Pros: A 12 inch ported subwoofer with a front port for flexible placement, for music and movies, now discontinued. 12-inch ported with 200W RMS outputs fairly accurate smooth bass for music and movies. Relaxed energetic low-frequency presentation without listening fatigue. Front-facing port enables flexible placement.

Cons: Maximum output in the upper bass trails the Infinity Speakers REFERENCE SUB R12, so it runs out of headroom sooner at high volume. Discontinued.
