Description
Overview
The Q Acoustics M40 HD is a powered wireless micro-tower music system designed for those who want full stereo sound without extra amps or clutter. Each pair includes a powered speaker and a passive speaker—just plug in power and connect the speakers, no external amplifier needed.
Standing about 710 mm tall, with built-in Bluetooth 5.0 streaming (supporting aptX HD, aptX Low Latency, AAC, SBC), USB, optical and analog inputs, the M40 HD offers flexible connectivity. The speaker uses C3 (Continuous Curved Cone) drivers for tight bass and controlled mids, with design features like internal bracing, decoupled tweeter and cabinet tuning to maintain clarity and reduce distortion.
Top Key Features (with “why it matters”)
-
50 W RMS per channel / 100 W peak power
Strong enough power to drive both speakers clearly, giving dynamic music playback and room-filling sound without needing an external amplifier. -

For wireless high-quality streaming, with minimal lag—useful for video or gaming. -

Rear port with foam bungs + EQ switch for wall/corner placement
Helps control boominess if speakers are near walls; improves bass tuning and avoids distortion from proximity effects. -
C3 driver & internal bracing design
Reduces cabinet resonance and distortion—improves clarity especially at higher volumes or complex passages. -
Full 38 Hz low-end (-6 dB), 22 kHz high-end

Common Questions (FAQ)
Q: Can I use these without an external amplifier?
Yes — the powered speaker has built-in amplification for both units; you just power it and link the passive speaker.
Q: Do they need a subwoofer?
They reach down to 38 Hz (-6 dB), which is strong for many genres. For very deep sub-bass (below 30-35 Hz) or large rooms, adding a sub will augment performance.
Q: Are they suitable for wall placement?
Yes, but be cautious. Use the foam bungs or EQ switch if placing near walls or in corners to manage bass response.
Q: What finishes are available?
Available in Black, White, and Walnut finishes.
