hi sheep,i get a kick outta the country music deal every time i read it but it pissed my wife off

she listens to that drool

too bad for her
an excellent designed "full range speaker" should go from atleast 20hz to 20,000hz & consist of bass,mid bass & high,it should also have a crossover point for each section of drivers,anything less than 20hz is not really full range for bass.
bass modules are subs but for good stereo seperation & imaging its far better sounding if you have a full stereo bass response either from the main speakers or stereo subs,a single sub is a mono speaker & will produce lots of bass but will not give great imaging & no stereo seperation.
recieving all the low end bass response from a single source is no different than recieving all the high end response from a single source,no stereo seperation.
as always my comments apply to the 2 channel music listening experience
