The RCF SUB 708 AS II Active Subwoofer harnesses 1,400 watts of power to infuse your sound system with thundering bass. Thanks to a custom designed 18" woofer and 3" voice coil, this active sub reaches lows of 35Hz for a full, impactful low end that brings your music to life. Whether you're a mobile DJ, own a music venue or need a high powered subwoofer for your house of worship, the SUB 708 AS II delivers the chest thumping lows you need.

Packed with Power

At the heart of the SUB 708 AS II is a potent 1,400 watt digital amplifier capable of peak SPLs of 133dB. This Class D amp achieves high output with minimal distortion, allowing the 18" woofer to reach deep, controlled lows. The woofer's 3" voice coil handles high amounts of power with ease, ensuring your low end remains tight and impactful even at the highest volumes.

Fine Tune Your Low End

Shape your subwoofer's frequency response to your venue's needs with the SUB 708 AS II's built in DSP. Adjust the crossover frequency to perfectly match RCF's 12" or 15" satellite speakers for a fully integrated system. Flip the phase switch to correct any phase issues, and rely on the electronic EQ to eliminate unwanted resonances. A soft limiter and driver protection work in tandem to prevent distortion even when pushing the amp to its max.

Roadworthy and Ready to Perform

Despite its formidable power, the SUB 708 AS II is designed to be highly portable. It weighs in at just 82.89 lbs. and features two recessed handles and an integrated pole mount for transporting and stacking with ease. Its rugged enclosure is built to withstand the rigors of live use, ensuring this subwoofer delivers high performance wherever your gigs may take you.

    Unless it's a "branded" speaker, manufacturers never provide that information.
