Default 10.3 compact bass reflex build

Received my 10.3 drivers from Mark a couple weeks back and couldn't wait to make cabinets for these. First Mark Audio drivers i've ever had. This is the end result, sound is really fantastic.

- Volume is approximately 15L after deducting for cone volume, port volume and a single brace.
- Width of the speaker is 22 cm, Height 40 cm and Depth 28.5 cm.
- Bass reflex port is sighted on the underside, internal diameter 64 mm (standard gutter pipe) length 22cm for tuning to 49 Hz according to WinISD.
- This should give -3dB at just under 50 Hz.
- 18mm MDF used throughout apart from the front panel, 25mm MDF.
- Rubber feet raise the cabinet 20mm off the table, allowing bass reflex to operate satisfactorily.
- Finishing used Zinsser 123 primer and automotive top coat.

More photos of the build from start to finish can be viewed at:

Excellent !
Very nice tidy package.
As mentioned elsewhere, these drivers take a while to really sound their best.

Nice job! I've had alpair 10.1 and 10.2's and enjoyed them very much. They just keep sounding better and better, even after 6 months of playing! ENJOY!
