But it's inconveniently large. I might order their iso cab, which is very ergonomic, and have them build an even bigger box to put around the iso cab. The outer box which would stay at home. It resonates slightly, at a high-bass frequency, when you strike it. Pressboard has a dull thud and is preferred.
Thicker wood is heavier but blocks sound more.
The choices are yours. Build a box with no two dimensions the same. Line it with fluffy material from a fabric store. Design a speaker mounting surface. I chose to let it float on top of the fluffy material, to avoid transferring vibrations to the cabinet.
