Engineered as the perfect partner for 8" or 10" speakers, it creates a full-range system that sounds substantial yet remains surprisingly portable. Prepare to add serious, punchy low-end to your setup with ease.
Crystal-Clear Power and Precision
This RCF Sub isn't just about making noise; it's about making great noise. It’s packed with smart technology that ensures every bass note is articulate and powerful, even when you push it to its limits.
1400-Watt Class-D Amplifier: This powerhouse amp delivers an incredible 1400 watts of peak power, providing massive sound pressure levels up to 133 dB. It’s all the headroom you need to fill small to mid-sized venues with deep, immersive bass without a hint of distortion.
Bass Motion Control (BMC): This is RCF's secret sauce. BMC is an advanced excursion management feature that allows the woofer to move freely without over-extending, resulting in deeper, tighter bass and enhanced linearity. It’s like having an invisible engineer constantly optimizing your sound.
Electronic Equalization, Soft Limiter, and Protection: Onboard processing ensures your subwoofer operates safely and sounds its best. The soft limiter prevents harsh clipping, while internal protections guard against overheating and overloads, giving you peace of mind during any performance.
Total Control Over Your Low-End
The SUB 708-AS MK3 puts you in the driver’s seat with a comprehensive control panel that makes system integration a breeze. Dialing in the perfect sound has never been easier.
Stereo Crossover with Switchable Frequencies: The built-in stereo crossover allows you to perfectly blend the sub with your main speakers. With selectable crossover points, you can fine-tune the frequency split to match your specific setup and room acoustics.
Polarity-Reverse Switch: Quickly fix phase issues between your sub and mains with the flip of a switch. This simple but crucial feature ensures your low-end is tight and punchy, not thin and canceled out.
Stereo XLR Input and Signal Output: Connectivity is simple and versatile. Run your stereo mix into the sub, and the crossover sends the high-passed signal to your main speakers via the stereo XLR outputs for a clean, professional setup.
Built for the Road
Designed for life on the move, this RCF Sub combines robust construction with practical features that make transport and setup effortless.
Rugged All-Wood Cabinet: The tour-grade plywood cabinet is built to withstand the bumps and scrapes of the road. It’s not just tough; it’s acoustically tuned to enhance the performance of the 18" woofer.
Scratch-Resistant Polyurea Coating: Finished with a heavy-duty polyurea coating, the SUB 708-AS MK3 is designed to look professional gig after gig, resisting scratches and dings.
Ergonomic and Lightweight: Despite its powerful 18" woofer, this subwoofer is designed for portability. Ergonomic handles make it easy to carry, so load-in and load-out are faster than ever.
The Bottom Line: Portable Powerhouse Bass
The RCF SUB 708-AS MK3 is the perfect solution for anyone needing reliable, high-output, and articulate bass in a portable package. It seamlessly integrates with your existing system, provides all the control you need, and is built to last. Add this sub to your setup and give your audience the powerful low-end experience they deserve.
