Short answer: the Klipsch RP-500M II. It ranks #27 of 168 bookshelf speakers by sound quality (rated 4.0/5) at $389.99 and is still sold new; the Pioneer Elite SP-EBS73-LR ranks #159 (rated 1.6/5) and is discontinued, so it is only an option used.
The Klipsch RP-500M II is the more accurate option. Major mid-range clarity improvement over the original Klipsch RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. Its measured preference score, a predictor of how neutral it sounds, is 5.22 against 3.22 for the Pioneer Elite SP-EBS73-LR. The tradeoff: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies.
The case for 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 catch: 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.
Buy the Klipsch RP-500M II. It is rated higher for sound quality and still sold new, while the Pioneer Elite SP-EBS73-LR is discontinued.

Older model: the Klipsch RP-500M (ranked lower, rated 3.4/5).
Same family: the Klipsch RP-600M II (larger bookshelf, rated 3.7/5), the Klipsch RP-5000F II (smallest floorstanding, rated 4/5), the Klipsch RP-6000F II (floorstanding, rated 3.9/5), the Klipsch RP-8000F II (floorstanding, rated 3.9/5), the Klipsch RP-8060FA II (largest floorstanding, estimated 3.8/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5), the Klipsch RP-504C II (largest center, rated 3.8/5), the Klipsch Reference Premiere RP-500SA II (smaller surround, estimated 3.5/5) and the Klipsch Reference Premiere RP-502S II (larger surround, estimated 3.5/5).
Pros: Major mid-range clarity improvement over the original Klipsch RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. More neutral and linear overall than its sibling Klipsch RP-600M II, which carries about 2-3dB more high-frequency energy and a touch more bass but less overall balance. Very precise soundstage imaging and instrument placement. Distortion through the midrange is cleaner than the previous generation. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies. Horizontal dispersion of about ±40-50° is narrower and more directive than the reviewer’s preference for a wider, more enveloping soundstage. Toeing the speaker out to widen the soundstage or soften on-axis brightness comes at some cost to imaging precision. Slightly less clean in the tweeter region than the midrange, likely tied to crossover placement, though not considered a dealbreaker. Low-frequency output is limited: measured around 95dB at 4 meters for the pair before the woofers started to unload, so a subwoofer is recommended for anyone wanting real bass rather than stepping up to a larger model.

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.
