WHO IT IS FOR
Who it is for
Primary roles
- The largest standard Serie T/x option for music and mixed cinema systems.
ARCHITECTURE
Verified features, explained in system context.
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
System / room matching notes
Connections, room context, installation and the listening objective are reviewed together before a configuration is proposed.
Fit to confirm
- 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.
Known boundaries
- 27 Hz is a manufacturer -6 dB specification, not measured response.
- No automatic quantity, placement or room recommendation is made.
- Global finish availability is not Australian availability.
ROOM & INSTALLATION
Conditions to establish before specification.
- The larger cabinet and active/passive driver layout require confirmed floor space and placement options.
- Published extension does not predict modal peaks, nulls, decay or seat-to-seat consistency.
