Know before you buy
Yes, you can use it with other systems, but it is specifically voiced to complement the FBT CLA604A and CLA608A column speakers. Its internal DSP is optimized for these pairings, though it remains a capable active subwoofer for any setup requiring a compact, high-output low-end boost.
The subwoofer is designed to be stacked vertically or horizontally to increase your total sound pressure level (SPL). You can combine multiple units to create a more powerful low-frequency array, making it a scalable solution for both small intimate gigs and larger event spaces.
Yes, birch plywood is an industry standard for professional audio because it offers excellent structural integrity and acoustic resonance while remaining relatively lightweight. It is significantly more robust than plastic or MDF enclosures, making it well-suited for the rigors of transport and live performance.
The onboard DSP handles essential tasks like equalization, filtering, and speaker protection automatically. This ensures the subwoofer performs at its best without the risk of damage from overdriving, while also maintaining a clean, consistent sound profile across different volume levels.
Yes, the unit features an M20 threaded socket on the top panel. This allows you to securely mount a pole for your column speakers, creating a clean, integrated look that saves floor space in smaller venues.
Weighing in at 20 kg with a compact 550 x 270 x 500 mm footprint, it is quite manageable for a single person to transport and set up. Its size-to-power ratio makes it an ideal choice for mobile DJs or performers who need professional-grade bass without the bulk of a traditional 15-inch or 18-inch sub.
