Short answer: the Reflector Audio Square Two for better sound quality, the KRK Classic 5 for the lower price. The Reflector Audio Square Two ranks #26 of 64 powered bookshelf speakers at $6499. The KRK Classic 5 ranks #30 at $280, $6219 cheaper.
What the KRK Classic 5 offers: High-quality Klippel NFS data produces a 5.22 Spinorama preference score with a subwoofer, essentially level with the Edifier MR4. Bass reaches 60.1Hz at -3dB and 54.2Hz at -6dB, and the speaker responds especially well to EQ: Spinorama’s corrected score rises from 2.71 to 5.34 without a subwoofer and from 5.22 to 7.71 with one. Watch for: The unequalized response has a large 6.5dB frequency-deviation band, elevated splashy treble above 4kHz, crossover directivity error, and sharply narrowing tweeter dispersion. Distortion becomes extreme below 50Hz. Its raw 2.71 preference score is weak without a subwoofer, so EQ and careful toe-in are strongly recommended.
What the Reflector Audio Square Two offers: An exceptionally flat on-axis deviation of just 0.10dB from a coaxial horn design (four 5” woofers around a compression-driver tweeter) giving nominal 60x60 degree directivity from a compact 32cm cube, with a well-damped bass-alignment Q of 1.31. Sound on Sound’s review praised its detailed, neutral sound that stays phase-coherent with no appreciable latency. Watch for: A directivity-index standard deviation of 4.90, well above the 3-4 range typical of most monitors this size, reflects the narrow, symmetric horn pattern that Sound on Sound and ASR forum members flagged as double-edged, helpful in some rooms but limiting the sweet spot in others. Predicted in-room smoothness (0.49) is only middling, not matching the excellent on-axis figure. It’s a low-volume Latvian product with no published warranty term found anywhere.
