Short answer: the Klipsch RP-600M II. It ranks #114 of 203 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the Aperion Audio Verus V8B ranks #183, rated 2.7/5, and costs $1,499, so there is not much of a tradeoff to weigh.
The Klipsch RP-600M II is the more accurate choice. Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original Klipsch RP-600M. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 3.65 for the Aperion Audio Verus V8B. Watch for: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The Aperion Audio Verus V8B is the deeper-bass choice. Low-distortion bass that reaches a reasonable level for an 8-inch mid-woofer: the reviewer had no complaints about bass cleanliness, just extension. Its bass reaches about 55Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. The catch: A large mid-range scoop from about 100Hz-500Hz strips out the “meat” of male and female vocals, giving the speaker an overall dull, subdued character the reviewer specifically didn’t care for.
Buy the Klipsch RP-600M II. It is rated higher for sound quality than the Aperion Audio Verus V8B and costs less, so only choose the other one for a particular feature it does better.

Older model: the Klipsch RP-600M (ranked lower, rated 2.9/5).
Same family: the Klipsch RP-500M II (smaller bookshelf, rated 4/5), 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 (largest floorstanding, rated 3.9/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5) and the Klipsch RP-504C II (largest center, rated 3.8/5).
Pros: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original Klipsch RP-600M. Roughly 10-20° wider horizontal radiation than the original, giving more soundstage envelopment while retaining precise imaging. A major step up in overall tonal neutrality compared to the original Klipsch RP-600M, largely eliminating that model’s midrange resonance issues. Unusually, sounds better with the grille on: the grille smooths out the elevated treble rather than degrading the sound, a rare trait among speakers the reviewer has tested. More refined back-panel hardware, including anodized binding posts and jumper cables for optional bi-amping. Responds well to EQ correction (verified using measurement software and a miniDSP), letting the on-axis response be made genuinely linear. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced. Horizontal dispersion is very slightly less linear across angles than the original Klipsch RP-600M, a minor trade-off for the wider overall radiation pattern. Klipsch’s marketed sensitivity (about 94.5dB) is, like the original, a half-space rating roughly 9dB above the anechoic reality (closer to 85-86dB). In-room bass rolls off around 60Hz in practice, and a 120Hz boost paired with a midrange scoop gives kick drums their “tambour” without real low-end weight: a subwoofer is still recommended. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Toeing the speaker out for better on-axis tonality (rather than using the grille) introduces slightly more diffuse imaging from added sidewall reflections.

Aperion Audio Verus V8B: $1,499 per pair Aperion Audio eBay
Pros: Low-distortion bass that reaches a reasonable level for an 8-inch mid-woofer: the reviewer had no complaints about bass cleanliness, just extension. Wide-enough horizontal radiation to give some room involvement without being uncomfortably narrow. HDF (high-density fiberboard) cabinet construction instead of the more typical MDF. Nice aesthetic in the gloss cherry finish (also available in black); solidly built at nearly 28 lbs each. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A large mid-range scoop from about 100Hz-500Hz strips out the “meat” of male and female vocals, giving the speaker an overall dull, subdued character the reviewer specifically didn’t care for. Two back-to-back resonant peaks (around 4kHz and 10kHz) cause sibilance and an overbearing hi-hat crispness on some tracks; toeing the speakers 30 degrees off-axis helps a little but doesn’t remove the underlying resonances. At $1499/pair, the reviewer felt EQ shouldn’t be necessary to get a satisfying result out of the box. Minimum impedance (EPDR) dips to around 3 ohms despite a 5.7-ohm nominal rating, so a Class AB amplifier needs to be 4-ohm capable. Bass extension is modest for an 8” driver: measured F3 55Hz/F10 39Hz, getting into the mid-40s Hz in-room rather than truly deep bass.
