Short answer: the Emotiva Airmotiv XB2. It ranks #40 of 130 bookshelf speakers by sound quality; the Mission LX-3 MKII ranks #80.
What the Emotiva Airmotiv XB2 offers: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value - rated a top-three performer for the money by Erin’s Audio Corner. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener - needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.
What the Mission LX-3 MKII offers: A large affordable standmount with a 6.5-inch woofer, 88dB rated sensitivity and useful bass. ASR measured 48Hz estimated in-room extension, a controlled Q of 0.60, a 5.52 subwoofer-assisted preference score and reasonable +/-55-degree horizontal coverage. Watch for: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt. The 345mm-tall, 8.4kg cabinet is bulky and current US availability is limited.
