Which comm. speaker mfgr. makes the best cabinet?


Which commercial speaker manufacturer makes the best FUNCTIONAL cabinet and why? What type cabinet? (reflex, sealed, T-line, etc?) I'm not talking about cabinet finish....but function and quality of design and construction. Quality of finish would be lowest priority.
Thanks for your comments!

Cabinet? If you're in Rhode Island, that's a Milkshake. A drug store in Warren, Rhode Island still has the soda fountain. They make great Coffee Cabinet with their own homemade coffee syrup.
Rockport Technologies makes a decent molded cabinet out of .375" fiberglass on the outside, .375" fiberglass on the inside and then 2" of stuff that sets up similar to MDF between the two shells.....These are made in a boatyard in Maine.....
