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.

Reviews

Very depth and detail accuracy Low End
Had them for a few days and Maaaaan blown away by the sound quality and option for different flavor you can set for less or more 808 Ho Lp Sc Phase knob and more definitely recommend.

Get it you need
I decided to get a subwoofer because one of the mastering engineers who i network with told me I needed more control with my low end. Well all I can say is he was right. I finally now all the low frequencies with my mixes. This sub is amazing and works very well with my focal twin shape monitors. Just make sure you do acoustic treatment before you buy a sub. But focal is amazing and always delivers.

Perfect subwoofer for my home studio!!
Paired this subwoofer with a set of Focal Shape 50's. My room is approx. 11.5' x 12' so medium to smaller sized room. It is tough getting the placement correct with any sub in smaller spaces not meant for high end audio listening, but I feel it was easier with this Focal Sub One. Came from a KRK 12s subwoofer which was a nightmare to balance out in my room...
I have it right under my desk offset to the right (played around with the positioning a few times due to standing waves). My room has moderate acoustic treatment and after setting up the Shapes, this sub, and dialing it in with some room correction software I feel I couldn't have a better setup for my needs (catered more towards a flat/reference sound for mixing/mastering).
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.
