Short answer: the XMechanik Mechano23 DIY. It ranks #6 of 179 bookshelf speakers by sound quality, rated 4.4/5, at $200; the Ascend Acoustics Luna V2 Mini-Monitor Titan ranks #10, rated 4.3/5, and costs $898, so there is little reason to consider the other one.
What the XMechanik Mechano23 DIY does well: A DIY bookshelf design with exceptionally accurate sound that rivals far pricier speakers for a modest parts cost. Watch for: This is a true DIY project.
The case for the Ascend Acoustics Luna V2 Mini-Monitor Titan: A tiny, affordable bookshelf speaker with accurate sound, a big soundstage for its size and a seven year warranty. The catch: On axis deviation measures 0.599dB average, a comparatively rough figure for this driver class, so a listener sitting dead center is more likely to notice unevenness than with the RAAL ribbon version of this same cabinet.
