TT 515-A PROFESSIONAL ACTIVE SPEAKER
A 2000 watt speaker that can fit in your palm
The two-channel 2000 W (1000 W RMS) amplifier is small, ultra-silent, and fanless.
Producing a Max SPL of 127 dB, is perfect for 3D/immersive sound, nearfield systems, and productions that demand extreme sound quality.
The rotatable 100x70 degree pattern reaches a wide area, perfectly matching the directivity of the woofers.
The internal DSP has a whole range of protections for the transducers and includes special FiRPHASE and BMC processing to achieve coherent distribution of sound without phase distortion and deep, tight bass at any volume.

A little box with superpowers
The amplifier integrates a low-noise 32-bit DSP circuit, controlled through the RCF proprietary RDNet network to easily handle soft clipping limiters, RMS limits, polarity, amplitude, timing, and equalization. All the settings, monitoring, and more advanced features are available inside the RDNet Networked Management software. The available control panel on the back adjusts volume, high-pass, 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.
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, TT 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 TT 515-A.

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.
100° X 70° rotatable constant-directivity waveguide
CMD horn that is easily rotatable in the field using only a screwdriver.
Precision transducers
Low Frequency
Two 5” cone drivers on a custom-designed phase plug to enhance midrange efficiency and extend horizontal coverage, matching the waveguide dispersion for perfect coverage continuity around the crossover point.
High Frequency
The high-performance 1.75" titanium dome compression driver is fitted on a 100° x 70° rotatable constant-directivity waveguide. This special waveguide and high-frequency transducer design allow excellent control of directional characteristics. In difficult acoustic environments, intelligibility is significantly increased.

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.

New perspective on linearity
RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener.
The special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.

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.
