Pros: Better behaved off-axis than its horizontal MTM layout suggests: Erin found only about 2dB midrange loss at 20° and useful coverage through roughly 30°. The early-reflections directivity index is sufficiently smooth that Erin’s miniDSP correction produced a notably flat result. Measured sensitivity is a useful 86.3dB, and the dual 6.5-inch format supplies good dialogue headroom for a low-cost center.

Cons: F3 is 76Hz, so a subwoofer and 80Hz crossover are required. Unequalized response is not especially flat and carries elevated treble; Erin recommended it primarily when EQ is available. Like every horizontally spaced MTM, midrange interference worsens beyond the central seats even though this example is better than expected. Four-ohm nominal impedance calls for a capable AVR or amplifier.

How it compares: Just above it: Monolith Encore B6 - $110 more, 1Hz lower bass extension (-3dB). Just below it: Buchardt S400 MKII - $2150 more, 1.6Hz lower bass extension (-3dB).
