Short answer: the XMechanik Mechano23 DIY. It ranks #6 of 87 bookshelf speakers by sound quality at $48; the Dynaudio Emit M10 ranks #56 and costs $800, so there is little reason to consider the other one.
What the XMechanik Mechano23 DIY offers: The bass alignment is unusually well damped, with a measured Q of 0.336, among the lowest of any speaker in this catalog, so the -3dB point at 77.6Hz rolls off cleanly instead of building into a resonant bump the way many small ported designs do. On axis deviation measures a tight 0.195dB average, and Audio Science Review’s independent Klippel NFS review called the predicted in room response nearly perfect, with directivity matching that beats some commercial designs costing many times more, all from about $200 in parts. Watch for: This is a true DIY project. There is no assembled unit to buy, drivers come from Madisound, the crossover kit comes separately from EZ Speaker Solutions, and the birch plywood cabinet has to be built and finished by hand. Listening window smoothness measures a moderate 0.47 and the sound power directivity index has more variation (standard deviation 4.02) than the tightest speakers in this catalog, so off axis energy isn’t quite as evenly controlled as the excellent on axis figures suggest.
What the Dynaudio Emit M10 offers: CEA2034 spinorama shows impressive, headphone-level distortion through the midrange and tweeter at 86dB SPL, with a well-executed port that keeps resonance low below the crossover. 28mm soft dome tweeter and 14cm MSP mid/bass driver. Watch for: Tuned toward a mild showroom sound with boosted upper bass and treble and a recessed midrange - the reviewer prefers speakers that get the 100Hz-3kHz range right, which this doesn’t. His verdict: cheaper speakers deliver much more balanced tonality, so he wouldn’t buy it for himself.
Buy the XMechanik Mechano23 DIY. It ranks higher for sound quality than the Dynaudio Emit M10 and costs less, so there is no real case for the other one.
