Polk L800 help
I posted before about the issues with my Polk L800. I bought these used and the previous owner broke off the binding post on the left speaker when bringing his hospice bed in. The family replace the binding post. I did. Rentable shooting today
I get sound out of all the tweeters and drivers when hooked up to amp and SDA cable plugged in. The problem was I would blow the fuse on any amp I tried when play loud. I wasn’t hearing a wide image and it was overly harsh.
I was planning on ordering a new binding post plate for the left speaker and maybe a new crossover
I just tried the following:
Unplugged the positive speaker cable on the right speaker and both tweeters and mid range work low bass out put
Plugged the positive back in and removed the negative cable and only outside tweeter and mid range work. No bass at all
Plugged both back in and went to the left speaker
Unplugged the negative speaker cable and outside tweeter and mid range worked. No bass Plugged back in and unplugged positive cable and no sound at all from the left speaker
What could cause this?

I would start by inspecting the replacement/repair job the family did to the broken binding post. Sounds to me like they screwed it up.

Agree. I was going to call Polk and see if they can provide a wiring schematic

Pull the right speaker binding post plate to compare the wiring with the left speaker...simple.Political Correctness'.........defined

Well, wouldn't it be just like the speaker that works at the binding posts?
One would think the problem is inside at the binding post. You could take pictures of both and post here. -
I will take some pics. Everything works like it should without the SDA cable attached

Both are wired the same. I actually swapped the binding post plates and the same result. Took out the woofers and see the crossover plate. Everything looks connected.
I called Polk. They were no help. Said they would escalate.
I guess I’ll wait to hear back. -
What amps were tried?
If I remember correctly balanced differential architecture amps were problematic. -
Proceed HPA3
B&K AVR 7270
Emotiva Basx
Paramount (can’t recall the model 5 channel
Same issue with all -
Are you sure you have dedicated right and left speakers as indicated on the binding post plate.
