The input power and the suitable amplifier power range are greater and it has a smaller internal volume (5.5 L instead of the 220's 6.3 L). The color options are also different. The normal black and silver are still there, but white has been replaced by Black Gloss. The Paradigm Cinema 330 were created with a curved and flat rigid plastic design made to be mounted on walls. This design, though great for wall mounting, makes it difficult to set it up vertically without the sold separately stands. These sold separately additions can run up to $139 for a pair of Premier LS25 steel-and-glass stands.
