RCF TT 808-AS Professional RDNet Active Subwoofer System

RCF TT 808-AS Compact Networked Touring Subwoofer Power

The RCF TT 808-AS is a compact, low-profile, professional active subwoofer designed to deliver deep, controlled low end wherever space and sightlines are at a premium. Inside its weather-treated Baltic birch plywood cabinet, two vented-loaded 8" neodymium woofers with 2.5" voice coils are driven by a 1000 W RMS Class-D amplifier, providing up to 129 dB max SPL across a 40 Hz to 400 Hz operating range.

A low-noise 32-bit DSP with onboard RDNet control manages soft clipping limiters, RMS limits, polarity, amplitude, delay, and equalization. Advanced Bass Motion Control (BMC) optimizes woofer excursion without relying on traditional high-pass filters, preserving phase integrity while maintaining deep, tight bass at any volume. Management and tuning can be handled via RDNet or directly from the rear panel using two preset buttons, a polarity button, a variable delay, and controls for gain, low-pass filter, TT 515-A custom crossover, and bypass.

The enclosure is engineered for real-world deployment: rubber feet on two sides, two M20 threaded pole mounts for horizontal or vertical orientation, and two stabilizing brackets to keep vertical placement stable and firm. A steel grille with acoustically transparent foam backing protects the woofers from dust and humidity, while the rugged black polyurea coating and weatherproof treatment support long-term touring and outdoor use.

Whether it is used stand-alone, in subwoofer arrays (including cardioid-style configurations via RDNet), or as the low-frequency complement to the TT 515-A, the TT 808-AS allows system designers to build powerful full-range rigs with an exceptionally small footprint. For Chicago DJs, immersive sound designers, and production companies, this subwoofer delivers big-system impact in stages, clubs, and venues where every inch of floor space counts.

• Real-world applications: Club installs, theaters, immersive rooms, rooftop patios, corporate ballrooms, and mobile stages built around TT+ systems.
• Sound roles: Main system sub, flown or stacked sub array element, cardioid array component, or low-frequency extension for TT 515-A tops.
• Deployment styles: Horizontal under-stage placement, vertical side placement with stabilizing brackets, or pole-mounted TT 515-A full-range stacks.
• User profile: Chicago DJs, rental houses, and production teams needing RDNet-enabled bass with minimal visual footprint.

Control Modes for the RCF TT 808-AS Subwoofer

The TT 808-AS combines onboard DSP, rear-panel controls, and full RDNet networked management so engineers can adapt the subwoofer to many system roles, from single-sub setups to complex arrays.

• RDNet onboard: Connect TT 808-AS via RDNet Ethercon to access device-level control, grouping, monitoring, and the integrated subwoofer array configurator.
• DSP processing: Internal 32-bit DSP handles soft clipping limiters, RMS limits, polarity, amplitude, delay, EQ, crossovers, and BMC processing.
• Presets and voicing: Two preset buttons on the rear panel provide quick access to factory-voiced responses for common deployment scenarios.
• Polarity and delay: A dedicated polarity button and variable delay adjustment on the back panel help align the TT 808-AS with mains and other subs in the rig.
• Rear-panel controls: Controls for gain, low-pass filter, TT 515-A custom crossover, and bypass are available without connecting a computer.
• Power management: A regulated power supply supports operation from 100 V to 260 V, keeping output consistent across different mains conditions.

In larger systems, these control tools make it straightforward to integrate the TT 808-AS into RDNet-based TT+ deployments, with repeatable presets for touring shows and fixed installations.

Compact 2x8-Inch Subwoofer With Full-Size Low-End Performance

At the heart of the TT 808-AS are two vented-loaded 8" neodymium woofers with 2.5" voice coils, driven by a 1000 W RMS amplifier. This combination delivers 129 dB max SPL while maintaining a remarkably small footprint that can sit unobtrusively under stages, against walls, or built into tight production spaces. The 40 Hz to 400 Hz range covers both musical sub-bass and upper bass content, letting the subwoofer support compact TT 515-A tops or other TT+ models without feeling lightweight.

For sound companies and venues that need high output but do not want large-format subwoofer stacks, the TT 808-AS offers a way to get into TT+ performance with less visual and physical impact. The low-profile design also makes it a strong fit for front-of-stage applications where sightlines and audience proximity are key concerns.

Bass Motion Control and RDNet DSP for Modern Low-Frequency Management

The TT 808-AS leverages Bass Motion Control to manage woofer excursion using a custom algorithm derived from a detailed map of the woofer’s dynamic behavior. Instead of relying on conventional high-pass filters that can alter phase response, BMC focuses only on limiting over-excursions, preserving low-frequency extension and linear, musical bass even when the subwoofer is pushed hard.

Inside the amplifier module, a low-noise 32-bit DSP under RDNet control manages limiters, polarity, amplitude, delay, equalization, and crossover behavior. Advanced tools such as the subwoofer array configurator within RDNet allow engineers to plan, simulate, and deploy sub arrays, including cardioid-style arrangements, while monitoring the status of each TT 808-AS in real time.

Touring-Grade Baltic Birch Cabinet With Weatherproof Treatment

The TT 808-AS cabinet is built from high-quality Baltic birch plywood with a weather-proof outer treatment, supporting both portable and installed use. A heavy-duty black polyurea coating resists scratches and wear, while a powder-coated steel grille and internal acoustically transparent sound foam help shield the woofers from dust and humidity.

Eight M10 threaded inserts and two M20 threaded pole mounts (top and side) provide multiple options for rigging and mounting. Rubber feet on two sides ensure the cabinet is stable whether it is placed horizontally or vertically, and two stabilizing brackets make vertical placement firm enough for repeated use. A separate housing for the amplifier supports thermal efficiency and long-term reliability, even under demanding schedules.

Designed to Pair Seamlessly With TT 515-A Full-Range Tops

The TT 808-AS is highlighted as the low-frequency complement for the TT 515-A, making it easy to build TT+ systems that share a consistent sonic signature. The rear control panel includes a TT 515-A custom crossover option, and the cabinet form factor is engineered so that TT 515-A tops can be pole-mounted directly above using the threaded M20 sockets.

This pairing supports wide-ranging configurations, from a compact two TT 515-A plus two TT 808-AS stereo system that fits into less than 200 liters of volume, up to multi-sub systems in larger venues. With TT+ phase and frequency compatibility, designers can mix and match TT 808-AS subs and TT 515-A tops in rigs that scale across Chicago clubs, theaters, immersive rooms, and mobile deployments.

How to Deploy the RCF TT 808-AS in the Field

Deployment starts with choosing the right physical orientation and role. For compact main systems, position the TT 808-AS horizontally at the front of the stage or dance floor, using the M20 pole mount on the top panel to support a TT 515-A or other TT+ top. In tight spaces or under balconies, flip the cabinet on its side, use the side M20 mount, and rely on the rubber feet and stabilizing brackets to keep vertical placement secure.

Once positioned, set basic levels and filters from the rear panel: adjust gain, choose the appropriate low-pass setting or TT 515-A custom crossover, and apply polarity and delay so that the sub integrates cleanly with the tops. For more complex systems, connect the TT 808-AS to your RDNet network to group subs, fine-tune EQ, align timing, and use the subwoofer array configurator when building multiple-sub systems.

• Single-sub DJ or live rig: One TT 808-AS under a TT 515-A per side, using the top M20 pole mount and rear-panel crossover preset.
• Distributed bass in small rooms: Multiple subs along the front of the room or under the stage, all managed via RDNet for consistent coverage.
• Arrayed low-frequency systems: Groups of TT 808-AS tuned and delayed in RDNet for directional or cardioid-style behavior where appropriate.

Treat the TT 808-AS as a flexible building block—whether it is a single under-stage sub or part of a managed array, it gives your TT+ systems powerful, controllable low end without dominating the room.
