External crossover for speakers (RTI6's)

I asked this question in bass management, but not sure if it was the right place. I am now asking it here.

Here's my setup. I just got a set of RTI speakers b/c of Fry's super discount :).
RTI6's for front left and right speakers
RTI4's for surround.
Older Onkyo 5.1 Receiver.

I have decided to turn subwoofer off on my receiver and use speaker wire inputs to my sub because it seems to be louder and clearer vs. the subwoofer out. Plus, thanks to the help on this thread, I learned that all subwoofer sound (even LFE) gets directed to front speakers as long as center and surrounds are set to "small" and subwoofer out on receiver is turned off. Based on this setup, my RTI6's get the full range of sound from my DVD/CD/FIOS TV Box (including LFE), since I am using speaker level inputs for my sub.

Now here are my questions:
Are the internal crossovers in the RTI6's setup to harmlessly roll of sound below their rating (I think 55hz), or am i potentially causing damage to my new speakers by sending all this bass to them?

If I could be causing damage, is there some sort of passive High-pass filter/crossover that I can put in between the subwoofer and the front left and right RTI6's?


I am use to car audio, so please excuse me if these questions are dumb.

Thanks in advance.
