Short answer: the ELAC Debut 2.0 B5.2. It ranks #47 of 87 bookshelf speakers by sound quality at $329; the Pioneer Elite SP-EBS73-LR ranks #82 and costs $749, so there is not much of a tradeoff to weigh.
What the ELAC Debut 2.0 B5.2 offers: 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. Watch for: 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 B6.2 instead when EQ is unavailable.
What the Pioneer Elite SP-EBS73-LR offers: 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. Watch for: 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.
Buy the ELAC Debut 2.0 B5.2. It ranks higher for sound quality than the Pioneer Elite SP-EBS73-LR and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Pioneer Elite SP-EBS73-LR. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
