Muscular musicality

User Manual

Made for music

If you associate subwoofers with the rumble of exploding starships, you are not alone. So many subwoofers are intended for home theater. The SpinSub subwoofer is expressly designed for music. You experience fast, accurate musical transients along with deep, clear, unexaggerated bass.

Tech Hive Editor’s Choice Award (2021)

“…the perfect low-frequency companion to the company’s SpinBase turntable speaker, pumping the bass from a remarkably vibration-free enclosure. (4.5/5)”

- Theo Nicolakis, Tech Hive

Setup simplicity

Even if you’ve never connected a subwoofer before, setup is a breeze. Just plug in. And play. When you switch on your SpinBase system, the subwoofer automatically powers up from standby.

Feedback, defeated

Subwoofers work by producing vibration. The business end of a turntable works by detecting vibration. So under normal circumstances, placing your turntable system in the same stand as a subwoofer is a recipe for a miserable distortion called “acoustic feedback.” Andover’s patent-pending IsoGroove® technology protects your turntable from vibration – and protects your music from feedback. Independent audio critics who rarely agree on anything have declared the technology “lived up to its billing” and “works as advertised” and called it “so amazing” and “genius.”

Class D amplifier

Most power amplifiers generate substantial heat along with the wattage. So it’s difficult to fit a powerful amplifier into a compact subwoofer. But that’s what we accomplished. Our Class D amplifier is remarkably cool and compact while delivering ample power.

A beautiful match for the SpinBase and SpinBase MAX systems

The subwoofer is designed to sit by itself. Or you can slide the subwoofer directly into the bottom shelf of the matching SpinStand™ rack to create a simple, immensely satisfying, integrated system.

How do I connect SpinSub to SpinBase?

SpinBases sold after January 1, 2021 feature a 3.5mm subwoofer output, which can connect to the SpinSub input. SpinSub comes with the 2M braided cable.

Does SpinSub work with other speaker systems?

Yes. SpinSub also pairs seamlessly with traditional audio systems (e.g. book shelf speakers) equipped with a compatible sub output.

What is the crossover and slope for the SpinSub when paired with the SpinBase?

The SpinSub Low pass filter is adjustable from 50-180Hz and is 12dB per Octave. We calibrated it such that with the frequency and level knobs knob centered it's at 85Hz, and blends nicely with Spinbase in most instances. However, room acoustics and placement may suggest tweaking either frequency, level, or both some instances.
