Short answer: the Emotiva Airmotiv XB2. It ranks #41 of 131 bookshelf speakers by sound quality, rated 4.2/5, at $549. The StarkSound Beta 5 ranks #50, rated 4.1/5, at $499, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Emotiva Airmotiv XB2 does well: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. The catch: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
The case for the StarkSound Beta 5: Impressive bass extension for the price: F3 at 52Hz, F10 at 37Hz, reaching down to 40-50Hz in-room with solid kick-drum impact. The tradeoff: Sensitivity undershoots its own spec: rated 86dB, measured closer to 83dB.
Buy the Emotiva Airmotiv XB2. It is rated higher for sound quality, and saving $50 with the StarkSound Beta 5 does not make up for the sound-quality gap.

Emotiva Airmotiv XB2: $549 per pair Emotiva eBay
Older models: the Emotiva B1+ (rated 4.1/5) and the Emotiva Airmotiv B2+ (ranked lower, rated 3/5).
Pros: 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. Measured bass extension of 62Hz (-3dB).
Cons: 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.

StarkSound Beta 5: $499.00 per pair Amazon eBay
Pros: Impressive bass extension for the price: F3 at 52Hz, F10 at 37Hz, reaching down to 40-50Hz in-room with solid kick-drum impact. Good harmonic distortion control at both moderate and loud listening levels. Solid build with a thick polycarbonate baffle meant to reduce cabinet resonance. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Sensitivity undershoots its own spec: rated 86dB, measured closer to 83dB. A resonance artifact shows up independently in the on-axis response, burst decay, and impedance measurements, hurting directivity. Multitone distortion spikes to about 10% in the 800Hz-1kHz range, tied to woofer excursion: a subwoofer crossover helps. Needs to sit close to the wall (about 10 inches) or be EQ’d if placed further out, since the midrange sounds thin and the treble boosted otherwise.
