#71 Martin Audio CDD12: $1,750 Passive eBay
Same family: the Martin Audio CDD-LIVE 8 (smallest powered model, estimated 3.4/5), the Martin Audio CDD-LIVE 12 (powered model, ranked higher, estimated 3.1/5), the Martin Audio CDD-LIVE 15 (largest powered model, estimated 3.5/5), the Martin Audio CDD5 (smaller passive model, estimated 3/5), the Martin Audio CDD6 (smaller passive model, estimated 3.1/5), the Martin Audio CDD8 (smaller passive model, rated 3.2/5), the Martin Audio CDD10 (smaller passive model, rated 3.1/5) and the Martin Audio CDD15 (larger passive model, rated 3.3/5).
Pros: A passive coaxial 12 inch install speaker whose coverage widens up close, keeping level even from the front row to the back. 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.
Is the Martin Audio CDD12 right for you?
Skip it if
- you want neutral sound: its measured preference score is 3.8 even with a subwoofer.
- you will not add a subwoofer: bass rolls off below about 95 Hz.
- you want the best value: the higher-rated QSC K12.2 costs about $850 less.
