This may be a silly question, but for anyone who's seen my recent, lengthy post about speaker shopping, you might understand my brain cramp. As I auditioned some Paradigms, (Monitor 5s at four corners with cc-370 as centre) the salesguy suggested setting them all to LARGE on my receiver and using the sub crossover setting at just about roll off (somewhere around 50/60hz, depending on the sub's variable settings) rather than the often suggested "standard" of 80hz, speakers to SMALL all around. For music, this worked beautifully, as the blend between mid-bass and lower bass appeared seamless. I did not test this with movies however. Later on I auditioned some B&W CM2s as mains, with DM600 S3s as rear surrounds and CMC centre (the DMs are necessary to stay in budget). I really focused on the CM2s in stereo mode w/o a sub and though their frequ. resp rates them at a higher cutoff on axis than the Paradigms (65hz vs 58hz), I found their bass phenomenal despite lacking a sub. The DMs are rated even higher at 75hz. I realize that it comes down to trying and hearing what I like. (I also know that these are two very different sounding speakers, see my lengthy post on my sonic epiphany for more details). Ultimately, though, I'd just like to know what's happening to the bass if I set all of these to LARGE, and set the sub crossover at 80hz, in this case. I know that each speaker will receive a full range signal but does this mean they will simply be overwhelmed by the lower frequency or will they play the frequencies they can and let the sub fill in the bottom (this applies to both sets of speakers)? This latter scenario is what the Paradigm dealer says will happen. If so, then why would anyone set their speakers to SMALL, unless they are truly tiny and would implode from the pressure? I have a vague understanding of crossover slopes and etc., but not enough to answer my own question. My concern here is to avoid the phenomenon of "double bass" that I've read about, though not experienced, when full-range towers are said to double the bass of the sub in certain bass management situations (over on the Outlaw Audio forum, there was quite a discussion of this about a month ago but I didn't understand all of it). Parenthetically, I'd like avoid abusing which ever set of speakers I end up purchasing.
