Duntech PCL-3 on-wall will xover at 80hz make easier to drive

If you crossover a "hard to drive" speaker, does it really make that much easier to drive if your amp is underpowered?

I picked up a sweet pair of Duntech PCL-3 on-wall speakers. They’re probably 30 years old but sound so dang good! However, I’m going to put them in the bedroom where I only watch tv on 2 channel with a little Marantz receiver at 50 wpm. These are pretty hard to push and 50wpc just isn’t enough.. But, if I add a sub and crossover the speakers at 80hz, how much does that ease the amp strain?

Keep in mind - this is not intended to be an audiophile setup.. The little marantz is perfect because it’s small and has HDMI ARC which is a must have for my tv watching.

Thoughts?

What is the model of the Marantz? It could have a DSP built in.

@fiesta75 I don't know what a DMM is.  It's a  Marantz NR1510.  I wanted it for it's small form and HDMI ARC capabilities which is hugely lacking in the 2ch world for people who want to watch tv and not use a 3rd party remote like the dreadful Harmony.  

This allows me to use my Sony tv's RF remote like it's intended but that's a different subject.

Yes, it definitely helps, in your case, simply set the front speakers to "small" on your Marantz NR1510.

Don't worry about a DMM, I just wondered if you could measure the impedance of the Duntech PLC-3's.
I believe imhififan has the correct solution; Set speakers to small and add a subwoofer. +1 imhififan.
