    RCF SUB 705AS MK3 15" 1400 Watt Powered Bass Reflex Subwoofer

    When your audience needs to feel the music, the RCF SUB 705AS MK3 delivers powerful, deep bass that transforms any space. This 15" subwoofer provides exceptional low-end performance, perfect for live sound in intimate clubs or mid-sized venues.

    RCF SUB 705AS MK3 Advanced DSP for Precision Performance

    Advanced DSP for Precision Performance

    Built for sound engineers and musicians who understand that great bass isn't just heard — it's experienced — this subwoofer combines professional-grade components with intuitive controls that make dialing in perfect sound surprisingly straightforward.

    • 1400-Watt Class-D Amplifier: This isn't just about raw power; it's about clean, efficient energy that translates every bass note with surgical precision. The Class-D design keeps the unit cool during marathon performances while delivering headroom that lets you push hard without distortion.
    • 15" High-Performance Woofer: The custom transducer features a high-power ceramic magnetic circuit that handles demanding material with ease. Whether it's the subtle thump of an acoustic bass or the punishing low end of electronic music, this driver reproduces it all with remarkable accuracy.
    • Bass Reflex Design: The carefully tuned port extends low-frequency response while maintaining tight, controlled bass. This means you get deep extension without the muddy boom that plagues lesser subwoofers.

    Precision Control for Every Application

    Getting great sound shouldn't require an engineering degree, which is why RCF designed the rear panel controls to be both comprehensive and user-friendly.

    • Stereo Crossover with Switchable Frequencies: Fine-tune exactly where your subwoofer hands off to your main speakers. This flexibility ensures seamless integration whether you're pairing it with 10" monitors or full-range 12" cabinets.
    • Polarity-Reverse Switch: Sometimes phase matters more than you'd expect. A simple flip of this switch can be the difference between bass that reinforces your mains and bass that cancels them out.
    • Electronic EQ and Soft Limiter: Built-in protection keeps your investment safe while the EQ helps you adapt to challenging room acoustics. The limiter works transparently, preventing damage without killing your dynamics.

    Built to Handle the Road

    Live sound gear needs to survive everything from load-in chaos to late-night teardowns, and the SUB 705AS MK3 is engineered for exactly that kind of punishment.

    • Rugged All-Wood Cabinet: Solid wood construction provides the acoustic performance you need while standing up to the rigors of touring. The scratch-resistant polyurea coating keeps it looking professional even after countless gigs.
    • Portable Design: Despite packing serious power, this subwoofer remains manageable for one-person setup and transport. Smart engineering means you don't need a roadie crew to get professional bass response.
    • Stereo XLR Connectivity: Professional connections ensure reliable signal path and easy integration into existing systems. The XLR outputs let you daisy-chain to your mains or additional subs without signal degradation.

    The RCF SUB 705AS MK3 bridges the gap between portable convenience and professional performance. It's the subwoofer that finally lets you have deep, controlled bass without sacrificing setup time or breaking your back during load-out.
