There's two schools of thought on this. Much depends upon the subwoofer(s) you're using and how the low-pass filter scheme works and how low the cutoff frequency is.

1.7's are a speaker you could let run full range and then match the subwoofer low-pass to the natural 1.7 roll-off. If your subwoofer can do that. That would be a second-order roll-off.

If your subwoofer is limited to fourth-order roll-off, then I think it would be preferable to roll-off the 1.7's to match that.

DSP crossovers allow to implement just about anything for this integration. Analog crossovers are much more limited.
