The Bose speakers, should really be mated to the Bose bass module,
that it was designed with. However >>>
If you are really going to use those little twinkle sounding speakers,
then you need a subwoofer that can play up to 250 hz, and a receiver
that will allow you to crossover to the sub higher than 200 hz. Those
twinkle little speakers play to around 220 hz -
Are you sure that you do not want to sell them twinkle little speakers,
and then buy something else, that will go down lower?
Quality wise, I more than likely would say go with that Polk sub. How-
it only plays up to 200hz.
