Yes, I'll agree with that 100%. The reasons for that being long and
complicated.


(2) No double wall with sand fill ?:-)


No need. The best structural material for speaker cabinets is a
composite made of a plywood outer ( for durability ) with an MDF inner
for damping. 'Honeycombing' the interior ( probably with MDF panels )


Huh? MDF is harder than pine ply.


Define 'harder' ! MDF is far better damped but prone to environmental plus
knocks and bumps damage.
