 Description:

Boasting impressive power ratings and controls for fine-tuning your sound, Infinity Reference amplifiers are an ideal way to send your music to new sonic heights.

The Reference 611a mono subwoofer amplifier boasts a high-efficiency design that ensures steady power delivery. Delivering 456 watts of power to a 4-ohm sub, or 657 watts to a pair of subs, the 611a is powerful enough to satisfy your inner bass head. And every Infinity Reference amplifier is certified to deliver power as advertised.

Variable frequency filters let you contour the output to suit the needs of your speakers. Infinity's Dynamic Bass Optimization (DBO) circuit provides variable "Q" slopes, adjustable bass controls that allow you to tune your sub to its enclosure for more efficient output and cleaner low-end kick.

If you have multiple amps in your system you'll appreciate how the preamp outputs simplify hooking up additional amps.
