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!

Actually, I'm wearing my Rockports at the office today. High end shoes with "sole", baby!
Ah! Sorry MYRAJ. What and why.
Well, I was leaving it as an all encompassing answer;
Best cabinet? Dynaudio / Why, Dynaudio.
I am sorry that was out of your understanding. In the future I will try to keep my all encompassing answers very clear. I hope that this clears up any misundr.
Rgrost, did someone say that Wilson used Carbon Fiber? I cannot find that post.
