Need Advice upgrade subs?

Hello Everyone I need some advice

I have 2 subwoofers :Klipsch R-100SW 10" Subwoofer

setup for my Home theater system which consists of a denon avr x4700h connected via a M5100x amp . I am also running some buttkickers via a daytona amp.

My Issue: when watching movies it feels as if i am missing something that Boom or chest pounding effects from the subs. The buttkickers do a good job but it feels like the subs are the problem or it's just me?
