of a loudspeaker system to perfectly match each application: size/weight,
logistic and operational setups, SPL needs, LF extension, cost limitations, as well
as sound engineer preferences (depending on different the type and size of the
event) or audio program characteristics and regional style taste for subwoofer
mixes.

for any given situation from within a family of products with common finish,
