The Denon will be plenty of power.
Don't get Hung Up on the Numbers.
Once you get this gear and put it together
you'll probably find it's enough.
if it's not, get 1 Million Watts.
I was never Banned but thanks.
Who wants to sit in a Movie Theater
with people who might have this virus
while they're wearing a Non Medical mask?
Most people wearing a mask is wearing a Non Medical piece of paper
that does nothing to stop the transmission of anything.
Due to space restrictions, I have my Towers, rear ported, right up against the wall.
They sound pretty darn good. People get "hung up" about speaker placement.
Nothing is perfect. Do what you think best.
I have a AC Infinity AIRCOM S6, Quiet Cooling Blower Fan System 12" Rear-Exhaust for Receivers, Amps, DVR, AV Cabinet Components.
50 or 60 Dollars on Amazon. This one blows the hot out to the back,
Keeps things COOL.
Worth getting
I have always tried to have the same 3 Speakers for the Front Sound Stage.
When I bought the RF82 II's I was using the Synergy F20 because it's large
and it did sound ok but I wasn't real Happy.
Crutchfield had One RF 82II left and I Grabbed it.
Now using it as My Center with my New Marantz.
Made a Big Difference as I like 4 & 5 Channel Music.
For 5 Channel Music a Big Center makes all the difference
because a lot of music come through the Center.
I also like the sound of this Marantz over the Denon.
I'm not using any Sound processing but I
do like the sound better.
Get a Big Center, it's worth it.
Very little wattage is usually required to drive speakers to
Normal Listening Levels.
Higher power levels are required for loud sounds.
More important is The Quality of the Amp over The Power Numbers.
Most AVR's are not Massive Beast that deliver 150 watts or more.
Many people use AVR's in the 75 to 100 watt range and do just fine.
I would check and make sure Every Driver is working.
I would Not set These to the Small settings since you're
running a Sub, I would turn off the sub until you
straighten things out.
Set these to Large speakers.
Any Marantz or Denon will be Great for Your System.
They both have high Quality Sound.
If you don't need Pre Outs for an Amp later,
look at lower priced Denons.
Ones with 80 watts will drive those speakers very well.
