Here for sale is the missing piece of your sound system. This isn't just a speaker; it's the heartbeat, the foundation, the soul-shaking rumble that turns watching a movie into a cinematic event and listening to a song into a private concert. I'm selling my Onkyo SKW-770 Powered Subwoofer, and it's looking almost as sharp as the day I first unboxed it. The front face is a deep, piano-black gloss that gives it a modern, high-end look, while the main cabinet is wrapped in a classic black wood grain. It’s elegant enough to fit into your living room décor without screaming for attention—until you want it to. Inside that handsome exterior is a 10-inch driver poised to deliver clean, tight, and powerful low-end frequencies. This is the kind of base that you don't just hear, you feel it in your chest. I'm the first and only owner. It's been my trusted audio companion, treated with respect in a smoke-free home. And here’s the honest truth: I have never, not once, turned the base control knob all the way up. My living room, and perhaps my relationship with my neighbors, simply couldn't handle the sheer power it holds in reserve. It has been driven with care, never red-lined or abused, which means the driver and amplifier are in prime condition, waiting for someone ready to truly let them loose. This is your chance to own a meticulously cared-for piece of audio equipment with untapped potential.
