I sincerely appreciate the responses to my inquiry about finding a subwoofer for my LaScalas. Living in somewhat isolated northern Ontario makes it hard to know what to look for without the benefit of a nearby dealer with a range of products to see and hear, let alone bring home for a trial.
I will definitely investigate SEL subs and the newer Klipsch subs. My travels will take me to Toronto and Montreal in the next couple of weeks. Hopefully I will find time to look up some audio shops that will give me a chance to hear the speakers suggested.
Thanks again!
