Mine are the MKII with American Cherry timber veneer, wonderful craftsmanship beautiful looking and well proportioned. Look even better with the covers off displaying the perfectly symmetrical driver and bass port setup. The quality of sound is superior to than many larger and more expensive speakers. They replaced a $1500 5.1 Yamaha surround system and with just two channels the clarity of movie dialogue and sound from Bluray DVD's is way better.

No weaknesses that I have found.
