Description
The RCF SUB 808-AS is a compact low-profile high-performance active subwoofer. It features two vented-loaded 8” cone woofers powered by a 2000 Watts two-channel amplifier -one for each woofer- on a baltic birch plywood cabinet painted with black or white polyurea and weatherproof treatment. Management and tuning are available via RDNet software. The cabinet features rubber feet on two sides and two threaded pole-mounts for horizontal and vertical placement. Two stabilizing brackets make the vertical placement stable and firm. SUB 808-AS can be used stand-alone, in subwoofer arrays, or as the low-frequency complement for KX 515-A speaker.
Advanced Electronics
The high-powered Class-D amplifiers, tailored for each transducer, deploy pristine sound with efficient heat dissipation at the lowest possible distortion, along with low power consumption.
High-end AD/DA conversion up to 96 kHz - 32-bit floating-point, and onboard DSP for the best sound quality. Thanks to the proprietary RDNet networked management and control, every KX speaker provides in-depth remote monitoring through multiple sensors. The system engineer has immediate feedback of transducer status, fan speed, temperature, VU meters, limiters and much more.
Legendary Woofers
RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, smaller dimensions compared to others in its category. Self-powered design, RDNet remote control, easy configuration of subwoofer arrays (i.e., cardioid subs), and impressive size/weight to SPL output ratio create an engaging, immersive experience for any audience.
Networked Control and Much More
RDNet is an advanced platform for integrated monitoring and control of sound systems - from small live and installed setups to massive arena systems. Based on a robust networked architecture, RDNet combines system control, line array design, and comprehensive audio measurements into a single powerful software package.
Engineers and technicians can intuitively manage every device on the network, from individual components to multiple groups. The platform provides full DSP control of compatible devices, with flexible configuration tools for perfectly tuning the system response at maximum speed. Users have real-time access and oversight of all key settings from a centralized interface.
A Stunning Sound System
Pair the KX 515-A with the SUB 808-AS subwoofer to extend the low-frequency range and create a powerful full-range main system with an incredibly small footprint. With multiple configuration options, the powerful DSP and RDNet remote management, there isn't a too big or too small venue.
Good Things Come in Small Packages
Uncompromising fidelity and power with KX sonic signature. This means you have perfect phase and frequency compatibility among all KX speakers so you can serve up a breathtaking sonic experience in all your applications.
An Unobstructed Stage
Uncompromised sound without blocking critical sightlines. The ultimate flexibility for tight spaces, small stages, and small gigs with extreme portability. You can pack a full-range stereo system with two KX 515-A, two 808-AS subwoofers, poles, and cables in less than 200-liters volume.
Built for Everyday Use
Use it as a compact and powerful main system or to supplement a larger system. The waterproof cabinet is built in high-strength baltic birch plywood coated with black, robust, and scratch-resistant polyurea paint. Attached to a solid machined aluminum structure at the back, the amplifier heat dissipation is efficient and the cabinet is sturdy and stiff. A strong powder-coated metal grille protects the front, and an acoustically transparent sound foam backing on the inside of the grille ensures protection from dust and humidity.
Rig It Anywhere
The only limit is your imagination. With multiple rigging accessories and the unobtrusive form factor of the cabinet, KX 515-A is suitable for a wide range of configurations including hanging, pole-, truss-, wall- or ceiling-mounting— at any angle in horizontal or vertical orientation. The rotatable waveguide (and rotatable logo) allows for perfect dispersion control at any position.
The speaker’s rigging is fast and easy using the practical Quick Fit socket to easily install accessories such as the clamp mount, pole mount, horizontal brackets, or using the two M10 threads on top and bottom of the cabinet. You will always find a place for KX 515-A.
Tour Ready Construction
Attached to a solid machined aluminum structure on the rear panel, the amplifier ensures efficient heat dissipation. The enclosure is internally reinforced and sturdy, equipped with waterproof powerCON TRUE1 TOP mains connectors, guaranteeing durability under any outdoor conditions.
Bass Motion Control
When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. The speaker equipped
with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.
The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.
