What do they mean for "long throw driver"??


I have a pair ot Totem´s Sttaf with a long throw bass/mid unit driven by a Primare I21 (2x75 W). Just how much can the staff´s move (excustion) safely?? I like the sound a lot, but I want to be sure if the staff´s can take all the watt´s the Primare can offer (without clipping the amp). The amp goes from 0-79 (volume) and at about 45-55 depending on the music program the mid/woofer is really moving and I want to be sure that I am on the safe side (not overpowering the speakers). My room is 10x16. Any comments out there??

As far as driving them goes, use your ears. If you hear the least bit of distorted sound, back the volume down some, until it sounds right. It could be either the amp or speaker distorting, but that(distortion) is a warning sign.
Thank you for your responses. As I said I like my current set up and I don not want to ruin the speakers! I just think that the mid/woofer (5 1/2") of the Totem´s look kind of fragile. Thnaks again.
Don't expect too much from a $20 woofer - definitely be careful not to over drive them.
