#23 Ascend Acoustics CMT-340 SE2: $798/pair Ascend Acoustics eBay

Pros: High-quality manufacturer Klippel NFS data shows smooth on-axis response (0.372 smoothness) and a strong 7.17 preference score with a subwoofer. Its dual 6.5-inch woofers, 92dB anechoic sensitivity, and 240W continuous power rating support high output and dynamics.

Cons: Bass rolls off early for the cabinet size: Spinorama estimates 77.6Hz at -3dB and 48.3Hz at -12dB, so a subwoofer is important for full-range use. The rear port needs placement clearance.

How it compares: Just above it: Arendal 1528 Monitor 8 - $5202 more, 7.6Hz lower bass extension (-3dB). Just below it: Wharfedale Super Linton - $1901 more, 3.8Hz lower bass extension (-3dB).
