"They provided excellent, low-distortion stereo reproduction with plenty of bass across all formats and are a bargain for the sound quality they produce. Three years after SoundStage! first reviewed a Q Acoustics product, I am now the sixth SoundStage! reviewer to be impressed with the excellence of the company’s creations on all fronts. A high-quality build married to high-quality sound, all at an affordable price."

"The Q Acoustics M20 is one of the best of its kind right now and is worth every penny of its $599 asking price."

"Q Acoustics has released an unfussy, just-add-source set of powered speakers that we find impossible to dislike. With all of the amplification squirrelled away in the master speaker and the plethora of connectivity and placement options covered, the M20 is far more likely to become your entire music system than it is simply your new desktop speakers – and for this money, you’ll be hard pushed to better the sound quality with hi-fi separates."

"Movies, music, and video games all get an audio upgrade with these Q Acoustics speakers, with a built-in amplifier and Bluetooth connectivity, they’re easy to combine with almost any home theater or music setup."

"Perfect for people who want to take their first steps into the world of high-end audio, you'd be walking the earth a long time looking for a powered speaker setup that sounds this good…If you're looking to update your sound system then this setup will take you into the realms of high-end audio without bankrupting you in the process. Pure quality!"

"These compact bookshelf speakers pack an awesome punch without taking up too much space…the sound on offer is excellent for the size of the speakers. All in all, these budget, powered speakers are an excellent buy and as a compact and versatile audio system, they offer superb value for money."

"High-definition sound, Bluetooth compatibility, and minimal design – what more could you ask for? At £400, Q Acoustics M20 HD powered speakers are compact, but offer a kicking sound profile! Its immersive sound, with clear, high-definition, is consistent across any input…the M20s are a firm favourite amongst the VF Team."
