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??

A 'long throw' driver like a woofer can move back and forth about an inch. The usual for a woofer is half an inch.
The coil former inside the driver is much longer in a 'long throw' woofer (or speaker) and has winding and a magnetic gap that are longer. (Usually) So the cone has a bigger depth it can move in and out. It moves more air and thus stronger low frequencies.
So you could see it really moving around when it is working hard.

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.
