Dual Active Sub with Next-gen Slatefiber Woofers

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.

Praise for the sales engineer

I forgot to mention in my review of this Focal Sub One 8-inch Powered Studio Subwoofer, that it was my sale engineer, Andrew Plassman, who recommended it. I would never have known to purchase this if he hadn't recognized it was what I was looking for. When I told him the sound I was getting from my Focal speakers was bland, he said a subwoofer was what was needed. I'm incredibly grateful for his recommendation and knowledge. A big "thank you" to Andrew!

A Studio Necessity

In my ignorance, I always thought subwoofers were only for home stereo and TV applications. I was wrong. This Focal Sub One 8-inch Powered Studio Subwoofer adds so much depth to what I'm hearing in my small studio, that I wish I had known about it years earlier. It literally makes the sound come alive, when before, without a subwoofer, it was drab -- even with Focal speakers. This subwoofer pushes what I'm hearing into greatness. This is a major, major enhancement to my original music and what I'm hearing.

It breaks the rules…

stereo input, mono output. The drivers face away from each other, but both reflex ports are parallel and face forwards. If this creates a cardioid sub, then the Focal Sub One has the ability to defy the geometry of your room. The opposing polarities of the drivers might make the corners to either side of the room not matter as much acoustically, and create a really focused sweet spot in the unification of the reflex ports. Whatever, I might be all wrong, but it's hard to imagine a better sounding sub. It's ridiculously powerful, super focused and defined, and has never even vaguely chuffed. I'd buy it again if the price was double what it is.
Rated 5/5

Perfect For My Setup

1st and foremost thanks Alan Finkbeiner for always giving me sound advice when it comes to purchasing the right equipment
The Sub One fits my studio perfectly. Now I can take the load off of my satellite monitors. You will definitely hear the low frequencies accurately. Be sure to calibrate it to your room. If possible use Sonarworks to calibrate.
