I have one new MCM 80-430 subwoofer cabinet real red oak veneer , 18" square , 60 liters internal volume, etc. ( looks exactly like an adire Rava cabinet) . Pre cut for a 12" woofer ( hole is about 11 1/8 ) and a terminal cup on rear . Can easily cut the back for any powered sub amp and or a port. They sell for $90.00 new + shipping. I will sell for $50.00 + actual cost of fed ex ground shipping from Virginia, 23294. I also have 3 more used ones excellent shape cut in back for amps with 3" dual flared ports installed. $20 ea. + actual shipping charge from 23294. You could easily cut a new piece of mdf spray paint it black and fasten it over the existing back if you don't want a ported cabinet. contact [email protected] if interested.
