Infinity's Room-Adaptive Bass Optimization System (RABOS), which includes a sound-level meter, a test disc, and instructions, greatly improves the SW-12's ability to cope with room interactions, which can make any sub sound louder or softer at certain frequencies. I measured the crossover control's range as 58 to 78 Hz (not 50 to 150 Hz, as marked), which means the sub will work best in systems with front speakers that can play down to 80 Hz or so.

How Does It Sound? The Infinity delivered strong, deep bass. It was especially powerful in the upper range, making midbass notes - like those from a tuba or an acoustic bass - a bit too prominent at times.

The Bottom Line Its combination of good looks, healthy deep-bass output, and RABOS room-tuning system make the SW-12 an attractive choice.
