I'm building a box for my Sundown X-10 v2 D2 and I just want to clairify that the Subwoofer needs 1.50 Cubic Feet of air space. Is that the recommended space or the Maximum?
Also Is the 1.50 ft^3 the amount of air space after total displacement or before?
And what about the port? 1.50 ft^3 including port volume or is 1.50 ft^3 excluding the port volume?
Thanks for the help
