WHO IT IS FOR
Who it is for
Primary roles
- For systems that have outgrown T/5x or T/7x in scale, while retaining REL High Level music integration and a separate LFE route.
ARCHITECTURE
Understand what each feature means in a complete system.
Installation and integration
Verify High Level wiring against amplifier topology. Maintain clearance for the rear controls and the down-firing passive radiator. Do not infer that a larger model or stereo pair is required without measurement.
SYSTEM / ROOM MATCHING
Will it fit the system you already own?
We consider connections, room context, installation and your listening priorities together before suggesting a configuration.
What to check for your system
- Provides High Level, low-level and dedicated LFE inputs.
- A candidate where the system requires more driver area and amplifier output than smaller T/x models.
- Model selection must be based on the complete system and room, not product hierarchy alone.
What to keep in mind
- 27 Hz is a manufacturer -6 dB specification, not measured response.
- No automatic quantity, placement or room recommendation is made.
- The 27 Hz figure is a manufacturer -6 dB specification. Global finish status is not Australian availability, and no automatic room-size or quantity claim should be made.
ROOM & INSTALLATION
What to confirm before choosing the final configuration.
- Medium-scale and capable two-channel or mixed-use systems with sufficient floor space and placement freedom.
- Confirm whether the larger model is needed for extension or output, or whether a second source would better address room distribution.
