Short answer: the JBL Studio 530. It ranks #38 of 74 bookshelf speakers by sound quality at $399; the Pioneer Elite SP-EBS73-LR ranks #69 and costs $749, so there is not much of a tradeoff to weigh.
What the JBL Studio 530 offers: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off. Watch for: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time.
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 JBL Studio 530. 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 74 bookshelf speakers, so look higher up the list instead.
