Short answer: the ELAC Debut 2.0 B5.2. It ranks #86 of 160 bookshelf speakers by sound quality (rated 3.2/5) at $269 and is still sold new; the Pioneer Elite SP-EBS73-LR ranks #152 (rated 1.6/5) and is discontinued, so it is only an option used.
The ELAC Debut 2.0 B5.2 is the more accurate option. Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Its measured preference score, a predictor of how neutral it sounds, is 5.02 against 3.22 for the Pioneer Elite SP-EBS73-LR. The catch: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance.
Why pick the Pioneer Elite SP-EBS73-LR: 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. The tradeoff: 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.

The Two Speakers In Full
ELAC Debut 2.0 B5.2: $269.00 per pair Amazon eBay
Newer model: the ELAC Debut 3.0 DB53, ranked higher, estimated 3.9/5.
Same family: the ELAC Debut 2.0 B6.2 (larger bookshelf, rated 3.5/5).
Pros: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger ELAC Debut 2.0 B6.2 instead when EQ is unavailable.

Pioneer Elite SP-EBS73-LR: $749 per pair Discontinued eBay
Same family: the Pioneer Elite SP-EC73 (center, rated 3.3/5).
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.
