Although crown are great amplifiers i would lean towards QSC
QSC amplifiers seems to have a stronger following than Crown, also although i cant remember where i saw it but QSC amplifiers seem to be better at delivering power into low Frequencies than similar Crown models. The cinema company i workerd for once used local maufactured amplifiers for the mains/surrounds (Australian monitor) yet we allways used QSC amplifiers for the LFE and never had problems...
In fact the subs had the problems... ahhh memories of the first screening of U571... Out of four driver two rattled afterwards and one was completly gone
