200 watts of power should be more than enough for most people (and most neighbours).
And aptX HD and aptX Adaptive are always welcome where Bluetooth connectivity is concerned.
As far as sound quality is concerned, there is plenty to enjoy here.
Q Acoustics' music system know-how, all the way to the floor…
That Q Acoustics knows exactly what its doing where products like this are concerned isnt really up for question.
After that, though, they become slightly different.
The primary speaker, by way of contrast, has plenty more going on.
The M40 HD is arguably as beautiful from the back as it is when staring at the grille
And theres a pre-out for a subwoofer for the truly antisocial among us.
Wireless connectivity, meanwhile, is strictly via Bluetooth.
Its the 5.0 variation, with SBC, AAC, aptX HD and Low Latency codec compatibility.
They’re still quite svelte, despite being obviously taller than Q Acoustics' bookshelf offerings
It features two Class D blocks of amplification, each of 100 watts.
This system sounds very much like it enjoys your favourite music almost as much as you do.
At every point in the frequency range, detail levels are impressively high and integration is smooth.
The remote certainly adds value – although volume adjustment is a slightly blunt affair
All the momentum the recording needs is available.
Other than this, though, its hard to find fault with the M40 HDs presentation.
Each cabinet also has a Helmholtz Pressure Equaliser to reduce internal pressure and further reduce unwanted internal vibrations.
As with the M20 HD, each grille is fixed and cannot be removed.
These functions are duplicated on the remote control handset thats supplied with the M40 HD.
Setting up the M40 HD couldnt really be much simpler.
Value score: 5/5
Q Acoustics M40 HD review: Should you buy it?
Space is at a premiumSmaller room?
Suddenly thats no impediment to getting a bigger sound - and without breaking the bank, either.
The M40 HD could cause you consternation.
