Finally got the MDF for my next subwoofer project in a MDF enclosure (no less!). This enclosure is going be one heavy box. I'll be cutting up the panels this weekend, and hopefully putting the enclosure together in the coming week(s). And of course most steps will be photo-documented. Project recap: Driver - original SVS 12" driver, 4.5 ft^3 of internal volume, tuned to 20Hz with a 4" wide flared port 18" long (19" total end-to-end), dual MDF layers for top and bottom, other vertical sides edges will be braced with 2x2's and there will be 2 other MDF braces evenly spaced in the horizontal orientation.
