Hi all, forgive the neophyte question and I apologize if this has been answered elsewhere. I might just not know the right terms to search to find the answer.
I'm currently am running a pair of Definitive AW6500 outdoor speakers off of my Dennon receiver. I love the speakers and am changing the configuration of my yard such that I'd like to add another pair to cover more area. The speakers are 8 ohm. How do I go about adding another pair without damaging the receiver?

There are universal answers but they are ugly. (Add series resistance.)
How many models of Denon are there? I can't see it from here. Yours may or may not support 4 Ohm loads.

It's a Dennon AVR-1912. I'm trying to find the impedance range, but can't seem to find it listed anywhere.
Ok, the receiver is a Dennon AVR-1912 and the manual says output impedance 6-16ohms. So it looks like I can just connect a pair of the 8ohm speakers in series to each channel and I'll be good to go at 16ohms. Correct?
So would a secondary amp for the outdoor speakers be the solution to avoid the volume drop? I'm not sure how I would connect a second amp.
It's an AVR. Read the back panel. It will likely allow you down to 6Ω on each channel. No need for a second amp. Read your manual, it will explain it.
Yes, it does allow me to go down to 6ohms, but two 8hm speakers will be 4ohms if wired in parallel (too low) and 16ohms in series (too much volume drop). I could switch to different speakers (ie: 4ohm speakers wired in series) to keep the same impedance that I have now, but I haven't found any that seem comparable to the ones I already have and like.
Firstly, you don't know how much the volume will drop and secondly, you can just turn it up more. It isn't clear yet how far you can do that.
According the charts I've found, I'll have a volume drop of about 50%, which is a lot. Now that I know I can safely connect the speakers in series, I could give that a try but I'm hoping to avoid buying $800 worth of speakers only to find out that the charts are right and I have to have the music inside blaring in order to get decent volume outside.
Please read this line again.
Incorrect. Think of a 7.1 receivers as 7 different amplifiers in one. You are not paralleling anything. You are adding an 8Ω load to each of four amplifiers. Three you won't be using. Your receiver says 6Ω is okay.
Sometime levels are adjustable so you won't lose a whole lot of volume on channels other than main.
If you only play at low volumes, a "6r" amp may tolerate 4r just fine. Until your drunken guest hears the start of "Light My Fire" and yells COWABUNGA!! TURN IT UP!!! and does just that.
That is an astonishingly complex sound system. It looks like 'Multi CH Stereo' will take one stereo pair input and distribute it to 'ALL' amplifier channels. Just wire-up one speaker per amplifier channel. It is OK to have 4 speakers on 7(6?) channels, the amplifier does not mind. (Tube amps could mind but this is no tube amp.)

I just checked, yes it does have speaker level calibration to allow you to determine how much comes out of each channel. This is important if you are using it for what you want. It also has auto calibration for if you are using it for home theatre.
