BluTube SG + HC655-16 4-Pair

This bundle combines the Rockville BluTube SG tube amplifier with eight HC655-16 6.5" in-ceiling speakers for multi-room audio driven by a single receiver. The HC655-16 speakers are 16 ohm, which is the key detail: wiring four per channel in parallel brings the load to 4 ohm, well within the BluTube SG's operating range. That means eight speakers from one amplifier with no impedance issues. The BluTube SG runs 70W through real vacuum tubes with Bluetooth, optical, coaxial, RCA, and USB inputs. Each pair of speakers handles 160W RMS through 6.5" polypropylene woofers with rubber surrounds and mylar dome tweeters. Aim-able swivel tweeters give you directional control over high frequencies, and paintable flush-mount grills let every speaker blend into any ceiling color. Spring-loaded push terminals make wiring simple. Eight speakers cover an open-concept main floor, or split across bedrooms, hallways, and living areas for background music throughout the house. The 60Hz-to-20kHz frequency range covers a wide bandwidth, and the receiver's sub output lets you add a powered subwoofer for deeper bass whenever you need it.
