Short answer: the Behringer B2030P for directivity at a lower price, the Klipsch RP-600M II for a more controlled top end. The B2030P costs $220 and its CEA2034 spinorama keeps the response nearly constant off-axis with a wide beamwidth, but an 800Hz resonance shows in the on-axis response, and its flat predicted in-room response sounds bright without EQ. The RP-600M II ranks #75 of 134 bookshelf speakers at $449.99, though its treble runs notably hot on-axis and needs about 20° of toe-out or the grille.
Buy the Klipsch RP-600M II. It is rated higher for sound quality; the Behringer B2030P is no longer sold new.

Klipsch RP-600M II: $449.99 per pair Amazon eBay
Older model: the Klipsch RP-600M (ranked lower, rated 2.9/5).
Pros: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original 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 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 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 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.

Behringer B2030P: $220 per pair Discontinued eBay
Pros: CEA2034 spinorama shows strong horizontal directivity control, keeping the response nearly constant off-axis through most of the audible spectrum, with a wide beamwidth that eases seating position and toe-in requirements. Distortion measurements hold up well against the pricier Revel M106 at both 86dB and 106dB SPL. With EQ to tame a resonance around 800Hz and a bit of a bass fill, the reviewer called it a “winner” that could play loud without bottoming out. Measured bass extension of 98.1Hz (-3dB), with a measured sensitivity of 84.5dB.
Cons: A resonance around 800Hz shows up clearly in the on-axis response and the waterfall/CSD plot, and the flat, near-horizontal predicted in-room response makes it sound bright without an equalization target curve. Vertical directivity is only typical, not exceptional. Long discontinued: the reviewer noted you’ll have to hunt for a used pair.
