TT 808-AS is a compact low-profile high-performance active subwoofer. It features two vented-loaded 8" cone woofers powered by a 1000 Watts two-channel amplifier -one for each woofer- on a baltic birch plywood cabinet painted with black polyurea and weatherproof treatment. Management and tuning are available via RDNet software or using the two preset buttons, a polarity button, and a variable delay accessible from the back panel. 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. TT 808-AS can be used stand-alone, in subwoofer arrays, or as the low-frequency complement for TT 515-A speaker.

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.

A little sub with superpowers

The amplifier integrates a low-noise 32-bit DSP circuit, controlled through the RCF proprietary RDNet Networked Management software. Internal DSP easily handles soft clipping limiters, RMS limits, polarity, amplitude, delay, and equalization. All settings, monitoring, and more advanced features, such as the subwoofer array configurator, are available inside RDNet. The rear control panel can be used to adjusts volume, low pass, TT 515-A custom crossover and bypass. The regulated power supply guarantees full power from 100 V to 260 V. The amplifier is housed in a unique Vibrostop floating aluminum panel for extra protection during transportation. Internal DSP processing includes multiple EQs, delays, crossovers, and a special BMC processing for a coherent distribution of sound without phase distortion and deep, tight bass at any volume.

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.

Built for everyday use

The cabinet is made of high-quality birch plywood with weather-proof outer treatment. The subs are lightweight and stackable, with eight M10 threaded inserts to allow easy rigging. Two M20 threaded pole mounts on the top and side allow the woofer to be used in vertical or horizontal configurations, with rubber feet on both sides. Two stabilizing brackets make the vertical placement stable and firm. The heavy-duty coating, the powder-coated metal grille, and the rugged structure of the cabinet withstand long-term use and transportation. Separate housing for the amplifier guarantees component efficiency and reliability. An acoustically transparent sound foam backing on the inside of the grille ensures protection from dust and humidity.

A stunning sound system

Pair the TT 515-A with the TT 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 TT+ sonic signature. This means you have perfect phase and frequency compatibility among all TT+ 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 TT 515-A, two 808-AS subwoofers, poles, and cables in less than 200-liters volume.

Networked control and much more
RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.
