Short answer: the XMechanik Mechano23 DIY. It ranks #6 of 87 bookshelf speakers by sound quality at $48; the Ascend Acoustics Luna V2 Mini-Monitor Titan ranks #10 and costs $898, 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 Ascend Acoustics Luna V2 Mini-Monitor Titan offers: A Klippel NFS optimized crossover and proprietary 4.5 inch long throw glass fiber woofer give this compact mini-monitor a large soundstage for its size, at Ascend’s most accessible price point. Backed by the same 7 year parts and labor warranty and hand matched pairs as Ascend’s larger models, with each unit shipped with its own production line frequency response printout. Watch for: On axis deviation measures 0.599dB average, the roughest figure of any speaker added to this catalog from spinorama.org’s current measurement set, so a listener sitting dead center is more likely to notice unevenness than with the RAAL ribbon version of this same cabinet. Bass extension is limited by the small 4.5 inch woofer to a measured 74.7Hz at -3dB, so it needs a subwoofer for full range listening. Ascend sells direct only, with no dealer network for an in person audition.
Buy the XMechanik Mechano23 DIY. It ranks higher for sound quality than the Ascend Acoustics Luna V2 Mini-Monitor Titan and costs less, so there is no real case for the other one.
