Searching for the perfect active sub to complete your 2.1 monitoring system? The Focal Sub One design leverages cutting-edge materials and engineering to advance the state of the art in studio monitoring. This compact twin active subwoofer employs dual 8-inch woofers with Slatefiber cones developed and handcrafted in Focal’s Saint-Étienne, France-based facility. Powered by 200 watts of optimized Class D bi-amplification and engineered to deliver flat tonal balance and outstanding dynamic range, the Sub One is a versatile, robust subwoofer that will complement your modern production environment and provide the honest, accurate monitoring, high SPL, and deep low-end extension you need to produce world-class results.

Unerring accuracy, outstanding performance

At the heart of the Sub One are the new Slatefiber LF drivers. The singular characteristics of the Slatefiber material used for the cones have dramatically improved the low-frequency extension, dynamic range, and sheer impact of the Sub One as compared with its predecessors. If your projects demand high SPL and ultra-deep low-end extension, you need a Sub One — it's a must-have add-on for your monitoring system.

You can trust Focal monitors

With their extended frequency response and precise imaging, Focal’s Sub One active studio subwoofer is engineered to reproduce your audio signal with unerring accuracy. But beyond its impressive performance, this sub is designed for flexible, seamless integration into you studio. The Sub One features a fully adjustable lowpass crossover, volume, phase polarity, and more. You also get LFE, left, and right inputs, left and right outputs, and a 2.1 low-frequency management system for optimum satellite return. Engineers at Sweetwater rely on Focal monitors to tell them the truth about what they’re recording. You can put your trust in them, too.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
