WHO IT IS FOR
Who it is for
Primary roles
- To extend smaller and medium-scale loudspeakers while preserving a music-led High Level connection path and a separate LFE route for mixed use.
ARCHITECTURE
Understand what each feature means in a complete system.
Installation and integration
Verify High Level wiring against the connected amplifier design. The standby switch is manufacturer-listed only on 220 V units. Do not vertically stack T/5x.
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 RCA and a separate LFE RCA path.
- A candidate where a compact enclosure and analogue Class A/B amplification are priorities.
- Connection and crossover decisions remain system-specific.
What to keep in mind
- The 32 Hz figure is a manufacturer -6 dB specification, not measured response.
- The global page’s sale status is not evidence of Australian availability. The 32 Hz figure is a manufacturer -6 dB specification.
- The global REL page currently says Final Sale; this is not Australian availability evidence.
ROOM & INSTALLATION
What to confirm before choosing the final configuration.
- Systems with limited floor space and realistic output requirements, where the subwoofer can be positioned and tuned rather than hidden arbitrarily.
- Confirm boundary clearance, listening level, main-speaker roll-off and whether the room problem is lack of extension or uneven distribution.
