Short answer: the Pioneer Elite SP-EBS73-LR for Atmos flexibility, with the RB42 the easier load, though neither ranks well in its class. The Pioneer combines a front-facing 3-way with an up-firing 2-way Dolby Atmos coaxial driver designed by Andrew Jones, but a wide dip between 3-10kHz makes it sound “somewhat dull” without EQ and its impedance dips below 4 ohms. The RB42 looks like a $400-500 speaker for $159.99, though its spinorama shows peaks and valleys from a few kHz up. Both are rated below 3.0/5 among the 90 bookshelf speakers, and the Philharmonic Ceramic Mini, ranked #2 at $900, is a better place to start if sound quality matters.
Buy the Micca RB42. It is rated higher for sound quality and still sold new, while the Pioneer Elite SP-EBS73-LR is discontinued.

The Two Speakers In Full
Micca RB42: $159.99 per pair Amazon eBay
Pros: Curved cabinet fit and finish look closer to a speaker costing three times as much. Rated for a wide 15-100W amplifier range with 4-8 ohm compatibility, giving flexibility with modest amplification. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 80dB.
Cons: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.” Off-axis response diverges heavily from on-axis, meaning tonality shifts with room and listening position in ways EQ can’t correct. Distorts and the woofer visibly flaps under moderate volume; low 83dB sensitivity makes it a harder amplifier load than its size suggests.

Pioneer Elite SP-EBS73-LR: $749 per pair Discontinued eBay
Pros: Unique dual-driver design combines a front-facing 3-way speaker with an up-firing 2-way Dolby Atmos coaxial driver in one cabinet, designed by Andrew Jones. With corrective EQ applied, the reviewer found “substantially more brilliance and detail,” and the up-firing Atmos driver produced “remarkable” spatial effects from a single box. Measured bass extension of 64.5Hz (-3dB).
Cons: A wide dip between 3-10kHz makes the front speaker sound “somewhat dull” without EQ, and impedance dips below 4 ohms demand a capable amplifier. Distortion is elevated at the crossover points, around 180Hz and 2600Hz. Amir concluded: “The hole in frequency response and high distortion around the crossover point rule out this speaker for any kind of hifi use, certainly at these prices.” Long discontinued.
