SpinSub: a 100-watt subwoofer designed to pair with the award-winning SpinBase Turntable Speaker System. SpinSub connects to SpinBase via its subwoofer output, and extends its low-end bass range – making the pairing a compact, full-range listening solution. SpinSub also pairs seamlessly with traditional audio systems (e.g. bookshelf speakers) equipped with a compatible sub output. SpinSub is designed around Andover’s patent pending IsoGroove technology, which reduces unnecessary vibrations to eliminate acoustic feedback. This enables SpinSub to be placed near a turntable, or even directly on a SpinStand (where it fits perfectly), without issue. SpinSub features a pair of 6.5-inch, long-excursion woofers whose cones push more air and are more efficient than a traditional 8-inch woofer. These woofers deliver extended bass response with precise control and impact, down to 32Hz. SpinSub also incorporates adjustable frequency and level controls to compensate for room acoustics and placement, or to match to other audio systems. SpinSub is wrapped with premium black or white fabric, designed to complement other Spin System products, including SpinBase, SpinStand, and more.
