Short answer: the Pioneer Elite SP-EBS73-LR for Atmos flexibility, the Polk T15 for a simple budget pair, though neither ranks well in its class. The Pioneer combines a front-facing 3-way speaker with an up-firing 2-way Dolby Atmos coaxial driver designed by Andrew Jones, but a wide dip between 3-10kHz makes it sound dull without EQ and impedance dips below 4 ohms. The T15 at $149 is far cheaper, though its on-axis response falls off from 3 to 6 kHz. 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 Polk T15. It is rated higher for sound quality, and the Pioneer Elite SP-EBS73-LR is discontinued, so it is only available used.

The Two Speakers In Full
Polk T15: $149.00 per pair Amazon eBay
Pros: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”

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.
