Short answer: the Ascend Acoustics Luna V2 Mini-Monitor Titan. It ranks #10 of 179 bookshelf speakers by sound quality, rated 4.3/5, at $898. The Polk T15 ranks #164, rated 1.9/5, at $149, $749 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Polk T15 does well: A very affordable bookshelf speaker for near-field desktop use. Watch for: Spinorama analysis shows a deep on-axis dip from 3 to 6kHz in the upper mids and lower treble, likely from tweeter-woofer phase cancellation directly on-axis.
The Ascend Acoustics Luna V2 Mini-Monitor Titan is the more accurate, deeper-bass option. A tiny, affordable bookshelf speaker with accurate sound, a big soundstage for its size and a seven year warranty. Its measured preference score, a predictor of how neutral it sounds, is 5.17 against 0.34 for the Polk T15. Its bass reaches about 74.7Hz before falling 3dB, against 88.6Hz for the Polk T15. Watch for: 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.
Buy the Ascend Acoustics Luna V2 Mini-Monitor Titan. It is rated higher for sound quality, and the $749 you would save on the Polk T15 does not close the gap.
