Listen to a song in stereo that you know has a strong center image. If the image is centered, then the Denon is right. If the image is everywhere but centre, the Denon is wrong.

Here is a good song for that if you have Spotify or Tidal. Nancy is dead centre. She's also deep back depending on speaker placement and room acoustics:

Wow, thanks for the tip Mojo! It turns out the Denon is correct, the left speaker is definitely wired backwards. When I play it with the wires reversed, she is dead center. When I play it with the wires plugged in the correct polarity plugs, she is singing all over the front.

So I will leave the left channel wired backwards.

I have to ask for the sake of completeness. Is the cable wired correctly at the Denon?

Hi Steve,

If you unplug the speaker wire and put a 9 volt battery wired + to + and - to - on the speaker input the woofers should move out. This test will eliminate the speaker being internally wired ok. The next step would be to follow the + speaker wire back to the Denon and be sure it is plugged into + output on the Denon. What sort of markings are on your speaker wire to designate + from -? In one instance when I was trouble shooting phase the printed designation on the speaker wire flipped sides on its way back to the amp. It is not unusual for the phase test from the receiver to be wrong; you can't beat the battery test and a good physical check of the wiring.

Hi Ian,

I did the 9 volt battery test and the speaker is now confirmed to be wired backwards. When I put + to +, the driver moves in. When I put + to - the driver moves out. I have banana plugs on my speaker cables and Red is +, Black is -, both sides.

Video is here: https://ufile.io/tyjverim

And here’s a picture of my cable.



It's no big deal, I don't mind flipping the wires around!
-Steve

Steve, on another note, how was that movie with the new set-up?

BTW, I keep my grills off. It makes a big difference for me on the mids and highs.

OMG, the movie was truly incredible! The new speakers and the amp made a huge difference. The kids even said they enjoyed the movie more in our theater than when we saw it at IMAX. The special effect scenes actually shook the room and we felt like we were in the movie. It was a real blast!

Speaking of which, I'm actually considering swapping out the drivers on the VP180 and replacing them with v4 drivers. Would it be a simple as just swapping out the 6 drivers? On the parts page they also have the crossover listed, but there is no version associated with it, so I'm assuming the crossover is the same.

Steve, I'd really recommend trading it in for a v4 with HP drivers. If money is an issue, trade it in for a 160v4 with an HP driver provided you have the height for the 160.
