How can you tell if a speaker has impedence dips?


I'm considering running two power amps in bridged mode to increase the power. I've read that the only disadvantage to this is that if the speaker has impedence dips below 8 ohms, this could be stressful to the amp. The speakers that I'm picking up in 2 weeks are the Paradigm Studio 20's which are 8 ohm speakers. How do I know if there are periodic impedence dips or if they stay at 8 ohms consistantly?

I had some 20's a few years back.
They arent real hard to drive.
At the time I had a Dynaco ST-70 @35 wpc that gave me good but not great SPL's.
The bass on these little guys is very tight and go deep enough for most pop,light jazz or light rock recordings.
