#48 Martin Audio CDD12 Passive eBay
Pros: Martin Audio’s Coaxial Differential Dispersion driver widens horizontal coverage from 60° far away to 110° up close, so level stays more even from front row to back. A 12-inch woofer shares its motor with a 1-inch compression driver in a 19kg birch cabinet, available in any RAL color for installs. Measured bass extension of 95Hz (-3dB).
Cons: Manufacturer measurements give a very low 0.82 standalone preference score and 3.80 with an ideal subwoofer, with a wide 4.0dB reference band and 0.821 listening-window deviation, so its tonal balance is very uneven. Bass measures 95Hz at -3dB. It is passive, aimed at installs, and sold only through dealers.
How it compares: Just above it: RCF ART 712-A MK4. Just below it: Audiofocus VENU 12a.
