Dual 18-Inch Neodymium Configuration
The RCF TTS 36-A subwoofer uses two 18-inch high-power neodymium woofers. Each transducer incorporates a 4.5-inch voice coil, providing the motor structure and thermal capacity required for a high-output professional subwoofer.
The dual 18-inch configuration gives the TTS 36-A substantial cone area for low-frequency reproduction. This makes it appropriate for systems where the subwoofer section needs to provide significant acoustic output beneath a professional main PA.
The enclosure uses a bass-reflex design, allowing the acoustic system to operate efficiently in its intended low-frequency range.
RCF specifies the TTS 36-A at up to 143 dB maximum SPL at 1 metre, making it a high-output subwoofer intended for professional sound reinforcement rather than conventional portable PA applications. 
RCF TTS 36-A Power and Amplification
A major feature of the RCF TTS 36-A subwoofer is its integrated amplification.
The system contains two 2000 W digital amplifiers, giving a total rated power of 4000 W RMS. RCF’s current specification lists total peak power at 8000 W. 
The amplification is integrated directly into the enclosure, eliminating the need for an external power amplifier dedicated to the subwoofer.
This makes system deployment more straightforward for professional production environments because the amplifier and DSP processing remain part of the subwoofer system.
The integrated amplifier architecture also means that the RCF TTS 36-A subwoofer is designed as a complete active low-frequency system rather than simply a pair of passive 18-inch drivers in a cabinet.
For rental companies, touring companies and event production businesses, this can simplify amplifier rack requirements while retaining network-based monitoring and DSP control.
RCF TTS 36-A DSP Processing
The RCF TTS 36-A subwoofer incorporates a digital signal processor operating at 96 kHz with 32-bit processing.
The DSP section provides control over the subwoofer’s operating parameters and includes functions for system integration.
RCF specifies adjustable high-pass frequencies from 30 Hz to 45 Hz and low-pass frequencies from 60 Hz to 90 Hz. The system also provides time-delay alignment functionality. 
The DSP architecture allows the TTS 36-A to be integrated into a larger sound reinforcement system while providing appropriate low-frequency filtering and alignment.
For a professional sound company, this is particularly useful when the subwoofer needs to be coordinated with the main loudspeaker system.
The RCF TTS 36-A subwoofer also provides protection functions including thermal, excursion and RMS protection, together with a soft limiter. 
RDNet Remote Control
One of the most important professional features of the RCF TTS 36-A subwoofer is its integrated RDNet connectivity.
RDNet is RCF’s networked control and monitoring platform. It allows compatible RCF systems to be monitored and controlled remotely over a network.
According to RCF, RDNet can be used to control parameters such as level, delay and EQ, as well as monitor connected devices and configure advanced subwoofer arrangements. 
For a professional touring system, remote control can be particularly useful because the engineer can manage compatible system parameters without physically accessing each loudspeaker.
The TTS 36-A includes RDNet EtherCON input and output connections, allowing it to be incorporated into an appropriate RDNet network.
This makes the RCF TTS 36-A subwoofer more than a high-output bass enclosure. It becomes a network-controlled component within a larger RCF professional sound system.
Cardioid Subwoofer Configuration
The RCF TTS 36-A subwoofer includes a cardioid preset capability for groups.
Cardioid subwoofer configurations are used to control the radiation pattern of low-frequency systems and reduce unwanted rearward energy.
A cardioid configuration generally requires multiple subwoofers arranged in a specific physical configuration and processed with appropriate delay, polarity and filtering settings.
The TTS 36-A provides DSP functions intended to support this type of professional subwoofer deployment. RCF specifically lists a cardioid preset for groups among the product’s features. 
This is particularly relevant to touring and event production because low-frequency energy can otherwise spread widely around a venue.
When correctly designed and deployed, directional subwoofer arrays can help manage bass coverage according to the requirements of the event and venue.
Frequency Response
The current RCF specification for the RCF TTS 36-A subwoofer lists a frequency response of:
35 Hz to 120 Hz
The maximum SPL is specified at:
143 dB at 1 metre. 
The usable frequency range and crossover settings make the TTS 36-A suitable for integration with professional full-range loudspeakers and line array systems.
The exact crossover point used in a complete PA system should be determined according to the main loudspeaker, subwoofer configuration, DSP preset and overall system design.
The current RCF documentation lists adjustable low-pass frequencies between 60 Hz and 90 Hz, together with high-pass frequencies from 30 Hz to 45 Hz. 
RCF TTS 36-A Connections
The RCF TTS 36-A subwoofer provides professional audio and network connections designed for integration into touring systems.
Audio input and output connections use XLR connectors, while RDNet networking uses EtherCON connections.
RCF specifies both balanced and unbalanced input signal compatibility and an input sensitivity range of -2 dBu to +10 dBu. 
The rear panel also provides PowerCON input and output connections for mains power distribution.
This connection architecture allows multiple units to be integrated into a professional system while maintaining suitable signal and network connectivity.
RCF TTS 36-A Cabinet Construction
The RCF TTS 36-A subwoofer is built for professional touring environments.
The cabinet is constructed from Baltic birch plywood, with a steel grille protecting the front of the transducers.
The current RCF specification lists four wheels, steel forklift bars and six side handles. 
The physical construction is intended to withstand the handling associated with professional event production and touring.
The combination of wheels, handles and forklift bars is particularly relevant because the TTS 36-A is a substantial enclosure weighing approximately 100 kg / 220.46 lb according to the current RCF specification. 
Because of its weight and dimensions, appropriate lifting, transportation and handling procedures should be used when deploying the system.
RCF TTS 36-A Dimensions and Weight
The current specifications list the following dimensions for the RCF TTS 36-A subwoofer:
Height: 525 mm / 20.67 inches
Width: 1170 mm / 46.06 inches
Depth: 850 mm / 33.46 inches
Weight: 100 kg / 220.46 lb 
These dimensions make the TTS 36-A a substantial touring subwoofer designed for professional system deployment rather than compact portable applications.
The integrated wheels and side handles assist with movement on suitable surfaces, while the forklift bars allow the enclosure to be handled using appropriate production equipment.
RCF TTS 36-A for Touring
The RCF TTS 36-A subwoofer was designed with professional touring and high-output sound reinforcement in mind.
Its dual 18-inch configuration, integrated 4000 W RMS amplification, high maximum SPL and network control make it suitable for applications requiring substantial low-frequency output.
Touring systems often need equipment that can withstand repeated transportation, setup and teardown. The Baltic birch plywood cabinet, steel grille, handles, wheels and forklift bars address the physical requirements associated with this type of professional deployment. 
The RDNet network also adds system management functionality that can be valuable when multiple subwoofers are deployed together.
RCF TTS 36-A for Concerts and Festivals
The RCF TTS 36-A subwoofer can be used as part of professional concert and festival sound systems where strong low-frequency reproduction is required.
The dual 18-inch configuration provides substantial low-frequency transducer area, while the integrated DSP allows the subwoofer to be configured within a larger system.
For outdoor festivals, the appropriate number of subwoofers should be determined according to the audience area, desired SPL, low-frequency coverage and overall system design.
The TTS 36-A should be used with appropriate RCF system presets and professional system processing rather than simply being connected and operated without consideration of the main PA configuration.
RCF TTS 36-A for Rental Companies
For professional rental companies, the RCF TTS 36-A subwoofer provides an integrated solution that combines transducers, amplification and DSP in one enclosure.
This can simplify system deployment because a separate amplifier channel is not required for the TTS 36-A itself.
The onboard RDNet interface also provides networked management capabilities when the system is deployed as part of a compatible RCF network.
For rental inventory, the physical dimensions and 100 kg weight should be considered when planning transportation, storage and loading procedures.
The four wheels and forklift bars can assist with handling, but the enclosure should still be moved using suitable professional equipment and adequate personnel.
RCF TTS 36-A for Professional PA Systems
The RCF TTS 36-A subwoofer can form the low-frequency section of a larger professional PA system.
Its 35 Hz to 120 Hz frequency response provides the low-frequency foundation beneath compatible main loudspeakers.
In a complete sound reinforcement system, the TTS 36-A can be integrated with professional full-range systems, line arrays and appropriate RCF processing.
The exact system configuration depends on the main loudspeaker model, number of subwoofers, venue, audience size and desired coverage.
The integrated crossover, delay and DSP functions allow the subwoofer to be configured as part of a properly aligned system. 
RCF TTS 36-A System Control
System control is a major part of the TTS 36-A architecture.
Through RDNet, compatible RCF systems can be remotely monitored and configured.
RCF describes RDNet as a management and control platform for small, medium and large arena-sized sound systems, as well as complex installations. The platform can provide control over parameters including level, delay, EQ and advanced subwoofer configurations. 
For engineers working on larger systems, this network functionality can reduce the need to physically access individual loudspeakers during system setup.
The RCF TTS 36-A subwoofer therefore combines high-output acoustic performance with the type of system-management functionality expected in professional touring and installation environments.
Protection and Reliability
The RCF TTS 36-A subwoofer incorporates several protection systems designed to safeguard the amplifier and transducers during operation.
RCF specifies thermal, excursion and RMS protection, together with a soft limiter. 
Thermal protection helps manage excessive heat conditions, while excursion and RMS protection are designed to keep the system operating within appropriate limits.
The limiter and DSP architecture work together to help control the system when it is operated at high levels.
As with any professional loudspeaker system, protection circuits are not a substitute for correct system design, appropriate presets or responsible operating levels.
