That will work well, not heard anything bad about the Dayton,I think the fear that a modern mid priced AVR can't handle something rated near 4 ohms even at high SPLs is misplaced.
Glad the OP found a nice inexpensive solution for his speakers.
I just think it is weird that a speaker touted to be for beginners is 4 ohms--just bad engineering IMHO. Works great for marketing, you can use the sensitivity rating at 2.83V into a 4 ohm speaker so it won't look so bad--and hide the 3dB loss in efficiency against true 85dB efficient 8 ohm speakers at best buy--sounds the same efficiency!
A friend of mine has a nephew that received an AVR for Christmas--now the single guy has surround fever. I was asked if his rather basic AVR would have any issues with the Pioneer AJ 6 ohm speakers--checked them, recalculated the specs at around 84dB and noted the 6 ohms. He is single so I am assuming he might actually want some SPL on occasion. Told him to get the Fluance SX6 8 ohm speakers, 89dB efficient and 5" woofers. Cost a little more, they are larger but much higher efficiency, better bass response and true 8 ohm impedance will let his AVR run as cool as possible.
Once he realized the AJ Pioneers would require 3 times the power of the Fluance speakers, then it sunk in. He just wants a basic multi-channel system, nothing too wild but prefers to run it for many years and be done with it.
Or so he thinks... hope it works for him out of the box and he is content. If not, then the RP160 might be in his future and I'll book him on the flight down the rabbit hole.
