REL Acoustics S/550 10 Inch Powered Subwoofer

<h2 style="font-size:1.25em;margin:0 0 0.35em 0;">What You Need to Know</h2>

<p style="margin:0 0 0.9em 0;line-height:1.55;">The REL S/550 is the gateway to the legendary Serie S&mdash;a subwoofer built for full-range loudspeakers and reference systems that demand effortless low-end support without sacrificing agility or tone. Its 10-inch CarbonAlloy active driver, capped with pure carbon fiber in a die-cast alloy chassis, sharpens attack and smooths decay, while a 12-inch carbon/carbon down-firing passive radiator extends response to a subterranean 19Hz with no port noise or bloat. A 550-watt RMS Linear Class D amplifier keeps it composed, tight, and perfectly timed&mdash;whether tracking a cello's low register or the thunder of an action scene.</p>

<p style="margin:0 0 0.9em 0;line-height:1.55;">Integration is the REL signature: the 100%-analog High-Level Speakon input (32-foot cable included) feeds the sub the same signal as your main speakers, with premium polypropylene input-filter capacitors borrowed from REL's Reference designs. Low-level RCA plus LFE on both RCA and XLR cover theater processors, and matching outputs support stereo pairs and stackable Line Array configurations&mdash;mounting hardware is in the box. Finished in eight coats of Piano Black or Gloss White lacquer.</p>
