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?

Have you measured the amp output voltage at the desired SPL? If so, what woud be your estimated requirements reg the amp output?
No, I don't have the equipment to even do that. I just know the amp struggles alot more with these and my Anthony Gallos as it does my Klipsches. Expected I know.
I just want to know if I can relieve some strain from the receiver of I crossover the speakers at 80hz.
I want to get rid of the Rotel amp I'm using and simplify.

If you don't know the voltage swing and current draw on the desired SPL, from a technical pov you cannot state that the amp doesn't deliver enough. Another clue: install a sound level meter app on your smartphone, measure the SPL and post the results.
You're going to have to provide more info on the SPL levels. At what frequency? Turned up how much? I would expect these to produce much less SPL than the Klipsches due to sensitivity. I just feel the Marantz struggles with these, hence I have to turn it up too loud and risk clipping. Maybe I should know more about what "hard to push" really means.
PCL-3s driven with 50 watts should peak 100dB. That ought to be loud enough for a bedroom.
The PCL-3 is a nominally 4Ω speaker and likely has a minimum of 3Ω, perhaps a little less. I suspect your Marantz receiver is current limiting.
What model Marantz reciver do you have?

I meant: pump up the volume of any set in your bedroom and tell us what your SPL meter app tells you. These apps are not very reliable, but within margins of 3dB is probably enough.
