WHO IT IS FOR

Primary roles
- Compact, music-first low-frequency support with a separate LFE path for mixed-use systems.
ARCHITECTURE
Verified features, explained in system context.
Installation and integration
Use the region-correct mains unit and maintain the ventilation clearances in the manual. High Level wiring must be verified for the connected amplifier, especially Class D, balanced or differential designs. The model is not designed for vertical line-array stacking.
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
- A candidate where High Level integration with a compatible amplifier is desired.
- Can also accept a low-level preamplifier signal or a dedicated RCA LFE signal.
- The final connection method must be checked against the amplifier topology and system goals.
Known boundaries
- The published 37 Hz figure is a manufacturer -6 dB specification, not measured in-room extension.
- No automatic room-size, speaker-pairing, quantity or placement claim is made.
- HT-Air MKII does not provide High Level wireless transmission.
ROOM & INSTALLATION
Conditions to establish before specification.
- Its small cabinet may help where floor space is constrained.
- Do not infer output, quantity or suitability from floor area alone; assess room geometry, openings, listening level and placement options.
