i have speaker qestions

[speakerz]

I don't understand your question. Are wanting to add a sub, use the floorstanders as sub or neither?

You can't run a speaker off a sub out, it has to have some amplification that's why subs have built in amps, for the most part. Whether the receiver will drive the floorstanders really depends on what speaker it is.

This might make more sense.. i have 2 floor speakers 3 ways they need 12" subwoofers they are sealed boxes will these subwoofers work....[url]http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=290-367[/url .............if these wont work do u no of any that will work for around the same price and power.....btw my stereo is a 4 speaker port pioneer sx-v500 any good? 290 watt
