Finishes
A Duratex durable coating is the standard finish. Maple, oak, and walnut are standard available veneers. Other veneers may be available, please contact us for details. A challenge with the Mariana 24 is its size requires 12' long veneer and even longer in the 24SS so veneer options are reduced (exotics likely not available).
For our veneered subwoofers, our standard stain colors are Natural, Golden Brown, Light Brown, Orange, Cherry, Dark Brown, Rosewood, Espresso, and Black. We can also do custom colors to match items such as cabinets or furniture.
Measurements
Ground plane measurements were taken in the middle of a field with the microphone 2 m from the subwoofer. More information on measurement equipment and processes can be found on the FAQs page.

CEA 2010-A Test Results
CEA 2010-A test results can generally be compared but they shouldn't be used as absolute comparisons as there will be differences between test setups and different sets of measurements. Our measurements follow the CEA 2010-A specifications since historically, more measurements utilize this standard vs the newer and less stringent CEA 2010-B test standards. Even though we follow the CEA 2010-A results, we do provide additional test results for 8, 10, 12.5, and 16 Hz since our subwoofers have capability well below the standard 20 Hz.
These results are out in the middle of a field to ensure no reflections interfere with the results. In a room, the bass below 20 Hz will be reinforced because the bass waves won't easily leave a room. With room-reinforced bass, the Mariana 24SC/SR/SS are flat to 6 Hz in a room with reference level output.
