RCF TT 808-AS

The RCF TT 808-AS is a compact low-profile high-performance active subwoofer. Featuring two vented-loaded 8" cone woofers and powered by a 1000 Watts two-channel amplifier, the TT 808-AS is 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.

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.

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.

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.

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.
