RCF SUB 705-AS MK3 15" Active PA Subwoofer Overview
The RCF SUB 705-AS MK3 is a powerful subwoofer with a 15-inch woofer and a bass reflex housing for punchy, extended bass. Its 1400 W Class D amplifier gives it a great deal of power, with a maximum SPL of 131 dB. Additional internal protection and all-new features include thermal and RMS limiting, as well as a soft audio limiter for consistency and clipping prevention.
The SUB 705-AS MK3 features an onboard stereo crossover with switchable frequencies for precise integration with any sound system, and a wider image. And for further control over your sound fidelity, it also offers volume, EQ, and phase controls, as well as RCF's Bass Motion Control excursion management system for a more linear response that prevents the woofer from travelling too far. Built from rugged plywood, this cabinet will last through any shows or tours that come its way.

Full Description
View Full DescriptionPowerful and efficient
Class D amplification makes for a more lightweight, efficient subwoofer that can maximise its output volume. Delivering up to 1400 W of peak power, the SUB 705-AS MK3 gains up to 131 dB of maximum SPL. Combined with RCF's Bass Motion Control technology, the woofer's motion is kept reasonable in spite of the amplifier's immense power, resulting in a consistent, linear, and loud low-end that resists clipping.
Stereo subwoofer
With stereo inputs and link/crossover outputs, the SUB 705-AS MK3 is best when matched with a pair of full-range PA speakers. Plus, with adjustable crossover frequency, and a polarity switch, you can achieve cardioid response with multiple units, or simply adjust your subwoofer to any speaker you want.
Built to tour
A good subwoofer should be able to endure challenging conditions, and RCF have built their new range to do just that. More lightweight and easy to carry thanks to their lighter amplification and ergonomic grips, these subwoofers can be stacked and stored easily. An M20 threaded pole mount lets you mount full-range speakers on top of the sub for easy arrays too. Its tough plywood cabinet with a polyurea coating and powder-coated grille resists corrosion and impact damage. Sound foam behind the grille protects internal circuitry from dust or humidity damage, and its front-venting ports make them suitable for use in recessed positions.
