RCF TT 25-A II Touring Power and Precision for High-Output Sets
RCF TT 25-A II is a TT+ touring-class active two-way built for the real world: fast load-ins, repeatable voicing, and the kind of SPL headroom you need when a room fills up and the set gets bigger. The onboard amplification delivers 1100 W RMS (2200 W Peak), driving a 15" neo woofer (3.5" v.c.) and a 1.5" neo compression driver (4.0" v.c.) for a compact top that stays accurate at high output.
Coverage is purpose-built for controlled throw and clean pattern management: a 90° x 60° constant-directivity horn that is 90° rotatable to match your room orientation. In the field, it is designed to keep intelligibility and impact consistent from the front row to the back, while maintaining the tightness touring engineers expect.
Control and protection are not afterthoughts. You get DSP processing, RDNet onboard control, and RCF’s phase-focused approach with FIRPHASE. The system also lists BASS MOTION CONTROL as part of its onboard toolset, supporting cleaner low-frequency behavior when the program material gets demanding.

Control Modes and Rear-Panel Workflow for RCF TT 25-A II
System Set Up Encoder (push + rotate) is the core local-control workflow. Each push selects a function; rotation changes the value. The 2-digit display shows settings, and when RDNet is actively connected, a rotating segment indicates network activity.
- Input Gain Reduction: Push once to enter gain reduction (indicator lights). Rotate to reduce input gain; reduction steps are 0.1 dB for the first 10 dB, then 1 dB steps, up to 99 dB maximum reduction.
- Speaker Delay: Push twice to enter delay. Rotate to set delay expressed in meters; steps are 0.1 m for the first 10 m, then 1 m steps, up to 20 m maximum.
- Preset Selection: Push three times to enter presets. There are 8 presets in three distance-based groups: CLOSE (C), LINEAR (L), FAR (F).
Preset Families (TT22-A II & TT25-A II):
- L1 Linear: Fully linear response target for outdoor/low-reverb spaces at medium distance and medium/high SPL.
- L2 Linear High Pass: L1 with 24 dB/oct high-pass at 100 Hz for sub-satellite systems, larger rigs, or speech-focused applications.
- L3 Linear Low Level - Playback: Linear with gentle +3 dB low-frequency support for lower-level playback use.
- L4 Linear Indoor: Linear with gentle -3 dB low-frequency shelf for reverberant indoor balance and indoor speech reproduction.
- C1 Close: For average listener distance under ~3 m; gentle -3 dB shelf in HF for natural, non-aggressive balance.
- C2 Close High Pass: C1 with 24 dB/oct high-pass at 100 Hz.
- F1 Far: For average listener distance beyond ~10 m; gentle +3 dB shelf in HF to offset air absorption for clarity at distance.
- F2 Far High Pass: F1 with 24 dB/oct high-pass at 100 Hz.
- Limiter Behavior: The limiter LED indicates soft clipping activity; occasional blinking can be normal, but continuous limiting indicates the system should be turned down.
- RDNet Local Setup / Bypass: When released, local setup is loaded and RDNet can monitor. When switched, the RDNet setup is loaded and bypasses local presets.
- RDNet IN/OUT: EtherCON connectors provide network control via RDNet software.
- Power: Powercon locking AC input and AC output for secure power wiring.
- Reset Procedure: With the unit off, keep the encoder pressed while powering on; the display indicates reset activity, and release when prompted by the procedure completing on the display.
Deeper Look: Touring Output, DSP Control, and Deployment Advantages in TT+
High-Output Active Architecture Built Around Touring Headroom
The TT 25-A II pairs an 1100 W RMS Class D platform (listed as 2200 W Peak) with a transducer set aimed at staying composed when you are pushing real program material. The 15" neo woofer and 1.5" neo compression driver are specified with large voice coils for sustained output and control, supporting a top box that can stay authoritative without turning harsh.
Coverage Control That Adapts to the Room, Not the Other Way Around
The horn’s 90° x 60° constant directivity coverage is designed for predictable pattern behavior in typical venues. The horn is also specified as 90° rotatable, which gives system techs a practical way to keep coverage aligned whether the box is flown, on a pole, or deployed wide on a stage edge.
DSP Processing, Protection, and the Tools That Keep the Mix Stable
TT 25-A II includes DSP processing and onboard protection schemes (listed protections include Thermal and HF, plus a Fast Limiter). The platform also calls out FIRPHASE and BASS MOTION CONTROL as part of the system’s tuning and stability toolset, supporting cleaner results at the edge of performance.
RDNet Onboard: Centralized Monitoring and Fast System Tuning
With RDNet onboard and Ethercon connectivity, the TT 25-A II supports network visibility for single boxes or grouped deployments. The workflow is designed for technicians who want centralized oversight of system settings and status rather than walking the room to confirm each cabinet.
Touring-Grade Cab and Hardware for Real Deployment Scenarios
The enclosure is specified as Baltic birch plywood with practical deployment hardware: 6x fly track, quick lock points, and a pole mount. This is the kind of physical feature set that matters when you are rotating between flown mains, pole-mounted satellite roles, and ground-stacked fills across different rooms and stages.
Connectivity and Power Routing That Fit Production Reality
Audio I/O is specified as XLR input (bal/unbal) and XLR output for loop-through, plus RDNet Ethercon in/out for network control. Power uses Powercon IN/OUT with convection cooling, supporting clean rack-to-stage wiring approaches where secure connectors and predictable cable runs matter.
How to Deploy RCF TT 25-A II in the Field
Deploy the TT 25-A II based on coverage goals first, then lock in voicing and timing from the rear-panel workflow. In practical terms: decide horn orientation and splay coverage, set the appropriate distance-based preset family, and use the built-in delay (in meters) to align with subs, delays, or fills.
- Pole-mount mains for mobile DJ rigs: Use the pole mount for fast ballroom setups; select CLOSE when the dancefloor is tight, LINEAR for typical rooms, and FAR when throw distance grows.
- Sub + top systems: When pairing with subs, consider the 100 Hz high-pass preset variants (L2/C2/F2) to tighten LF handoff and keep headroom on the top.
- Delay alignment: Use the delay setting in meters (up to 20 m) to time-align fills or compensate for placement differences in long rooms.
- Flown or rigged installs: Use the specified rigging points (fly track, quick lock) and keep coverage consistent by rotating the horn as needed.
- Signal daisy chaining: Use XLR loop-through for clean feed-forward cabling to additional powered boxes.
- Power routing: Use Powercon IN/OUT for secure stage power runs; when chaining power, ensure current requirements stay within the connector/system limits.
Set coverage first, then lock presets and meter-based delay for a repeatable TT+ deployment that stays consistent from soundcheck to last track.

Frequently Asked Questions — RCF TT 25-A II
What is the quickest way to voice the TT 25-A II for different room depths?
Use the distance-based preset groups: CLOSE for short throw, LINEAR for typical listening distance, and FAR when the audience is farther away. These presets are designed to keep balance and intelligibility consistent across different placements.
How do I time-align TT 25-A II tops to fills or delay speakers?
Use the built-in delay function on the rear encoder. Delay is set in meters with fine steps up to 10 m and larger steps beyond that, with a maximum of 20 m, allowing fast alignment across long rooms or distributed systems.
For DJ use, when should I use the 100 Hz high-pass presets?
Use the high-pass variants when the TT 25-A II is deployed as a top over subs, or when you want tighter LF control and more headroom in the top. The high-pass presets apply a 24 dB/oct filter at 100 Hz within the preset family.
What does RDNet change in day-to-day deployment?
RDNet enables network monitoring and control through Ethercon connections, letting techs oversee compatible devices from a centralized interface. The rear-panel RDNet local setup/bypass determines whether local presets are used or an RDNet-loaded setup overrides them.
