Short answer: the Definitive Technology ProMonitor 1000 for value, the Pioneer Elite SP-EBS73-LR for Atmos flexibility, though neither ranks well in its class. The Pioneer packs a front 3-way plus an up-firing 2-way Dolby Atmos coaxial driver in one cabinet, but a wide dip between 3-10kHz makes it sound somewhat dull without EQ and its impedance dips below 4 ohms. The ProMonitor 1000 controls bass distortion but loses bass energy from 40-120Hz and resonates near 14kHz. Both are rated below 3.0/5 among the 90 bookshelf speakers, so if sound quality matters, consider the Philharmonic Ceramic Mini instead, ranked #2 at $900.
Buy the Definitive Technology ProMonitor 1000. It is rated higher for sound quality and still sold new, while the Pioneer Elite SP-EBS73-LR is discontinued.

Definitive Technology ProMonitor 1000: $498 per pair Amazon eBay
Pros: Bass distortion is well controlled per the measurements, and the slow bass rolloff means it can be pushed fairly hard for its size. Ships with a footer that keeps the small cabinet planted despite its light weight. Measured bass extension of 95Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows severely reduced bass energy between 40-120Hz, a directivity mismatch between the tweeter and woofer, and a severe resonance/interference issue around 14kHz. Distortion at 96dB SPL was so bad the reviewer limited testing to 86dB. Direct comparison to a $118/pair Pioneer SP-BS22-LR left the reviewer calling the $249/pair ProMonitor 1000 “a bad experiment that should be forgotten” and concluding “there is nothing Pro about it.”

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.
