Ok, I'm not arguing anything, just trying to piece this together as this is the first time I've seen this many binding posts on a speaker. My experience only goes back roughly 8 years and I don't claim to know it all. Which of the three posts would you suggest I use? The receiver that was hooked up wouldn't even power up anymore, so I wanted to make sure that the unnecessary bi-wiring wasn't the culprit. Also, do you think there will plenty of low-frequency extension just running them large?
