USES
Using the Tzero MKIII
Purpose
- Tzero MKIII is a compact option for a small music system or desk-based setup used at moderate listening levels. Its small cabinet makes it easier to look for a position beside existing furniture. Start with the bass you feel is missing in familiar music and the connections available on your amplifier.

CONNECTIONS
Connections and system matching
Check the inputs and outputs against the equipment you already use. If you have a connection question, send us the model names or a photograph of the sockets.
Connecting and setting up
- High Level takes a signal from a compatible amplifier’s speaker terminals. Alternatively, connect a volume-controlled preamplifier output to the RCA Low Level input.
- The separate RCA .1/LFE input connects to an AV receiver or processor’s subwoofer output, with its own level control.
- Use High Level or Low Level, not both together. For High Level, follow the instructions for your exact amplifier, including any Class D, balanced, bridged or monoblock requirements.
Points to consider
- The quoted low-frequency extension is a manufacturer specification. Bass level and decay at your seat also depend on placement and the room.
INSTALLATION
Placement and installation
- Keep the supplied feet fitted and leave the space beneath the downward-facing driver or radiator clear. Allow access to the rear controls and cables. This model is not designed for vertical stacking.
- Try the available positions, then adjust level, crossover and phase while listening with the main speakers at your usual volume.
- Use the correct mains-voltage version and preserve the ventilation clearances in the manual.

Configuration and included items
HT-Air MKII is an optional wireless system for line-level or LFE audio. It is sold separately, and the subwoofer still needs mains power.
ROOM MEASUREMENT
Understand how bass behaves in your room.
Room & Bass Measurement checks which bass frequencies stand out or fade slowly, and how a subwoofer works with your main speakers. We listen with you, measure and try practical adjustments where possible. No product purchase is required.
FAQ
Common questions
Can Tzero MKIII use wireless audio?+
Yes, with the optional HT-Air MKII system for a line-level or LFE signal. That accessory does not carry High Level audio. The wired High Level input remains an option for a suitable amplifier, and the subwoofer still needs mains power.
What does the Australian price for Tzero MKIII cover?+
$949 is the price for one subwoofer, including GST, with a 3-year standard Australian warranty. Any optional accessories and delivery timing will be listed in your quotation. These warranty terms do not limit statutory consumer guarantees under Australian Consumer Law.
