When you add the Focal CMS SUB to your monitor setup, you instantly improve your studio. Period. This 11" Active Studio Subwoofer doesn't simply add low-end content to your system; it also gives you the detail you need to really hear what you're doing to the low end in your mixes. We love Focal because they make incredible-sounding speakers that never, ever skimp on quality and that means speakers you can count on for a long time. When you're in a critical listening situation, you demand accuracy and reliability. Focal built the CMS SUB to give you both.
