It's time for a winter project.
I am thinking to replace my 2 sealed 18-D2's with a pair of Nick's HS24's. The target volume is 15 cubic feet per cabinet. I am trying to constrain the width and depth by building upward.
My current design is outlined below, with renders showing the structure of the bracing.
15.224 cubic ft (before the driver)
190 lbs (before the driver)
Triple 3/4" baffle, with single 3/4" wall elsewhere
All panels braced no less than every 7 inches
Rabbet joints all around
Before I start making dust, I want hear some thoughts on the adequacy of the cabinet's mass to tame this beastly driver. In Ricci's review
of the driver, he mentioned excessive shaking of his heavy test stand. One other (can't remember where) suggested bolting his cabinet to the floor would be helpful. Sibuna's cabinet showed some tremoring
Give me some feedback.
If I used 1" MDF for the walls, assuming the same external dimensions, that would bring my unloaded weight to 222 lbs. I have access to that material, but I don't want to add the weight if it isn't necessary.
