Bass Amps. JBL 4350

Hi all., Is it possible to tell any difference between bass amps on my  JBL 4350 woofers which crossover at 250 hertz.  If for example below 250 hertz I used Bryston 28bsst2  or, Mac 601, or Pass Labs X-600, or X 350  or just a Crown K2 as I have now. ?  Any opinions appreciated.
