To sum up, Q Acoustics’ Q Active 200 system is a fascinatingly different design, and I enjoyed my sojourn with it. It’s dead-perfect for the listener who might otherwise buy a brand-S or brand-B (or a Google or Amazon or Apple) all-in-one, but desires, and is willing to pay for, something much better, which this system most decidedly is. Could you, for the same money, get a bit better performance from conventionally wired passive speakers? Certainly, but you will sacrifice the integration, simplicity, and, of course, wireless-ness. And you’ll need to spend significant bucks for sources and for amplifiers as well. For anyone who finds the Q Active 200’s just- add-music concept alluring, I strongly recommend pursuing a serious audition.

This is more observation than criticism, as I’m wary of expecting too much from a loudspeaker at this price that performs so admirably in other areas. For instance, the EM-ESL X steers clear of HF nasties. Hi-hats and cymbals were always distinct and well separated, avoiding splash or brightness. Metallica’s ‘Dyer’s Eve’, which closes an album famed for a treble-heavy ‘scooped’ guitar tone […And Justice For All; Vertigo 836062-2] was perhaps more listenable than I’ve ever heard it, helped by the EM-ESL X’s speedy transducer keeping its frantic rhythms and riffs astonishing clear.

Lastly, for a simple five-minute demonstration of what this loudspeaker can do, give Elton John’s ‘Honky Cat’ [Honky Chateau; Mercury 528 162-2] a whirl. Huge piano accompaniment, dynamic trombone and saxophone hits, a drum track that sounds almost three-dimensional and Reginald Dwight throwing out rhyming couplets right into your listening room. It sounded… electrifying.

Digging down a little deeper into the cabinet design reveals another type of sandwich. The Plural Evo cabinet is made of three different types and layers of wood to reduce the material’s sound. These include high quality MDF, armored wood sandwich and vibration insulation. The woods are of different thicknesses and key positions in the cabinet are reinforced with metal plates. Internal reinforcements and bracing are asymmetrical throughout to reduce cabinet vibration to an absolute minimum. ZELLATON uses a special Laser Doppler vibrometer to measure the speaker’s vibrations down to the square centimeter.

Finally, ZELLATON eschews conventional philosophy of spiking speakers and prefers instead to use coupling in concert with energy draining. ZELLATON in the Plural Evos opted to use rounded feet on the bottom of the speaker in concert with discs reduce energy; a side benefit is this works better with carpeting.
