Hello, I've got two three pretty basic questions, or so I think... Luckily when my father upgraded his sound system in the early ninety's, he saved all four of his NLA's. But at a garage sale about 7 years ago, my father put them up for sale, no takers, phew, but he did sell a pair of the advent woofers that were in the currently unused pair of NLA's. Are there any places that sell new woofer replacements? I know ebay has them used but he won't help pay for them if I get used ones. I saw some on Simply Speakers for $130 per woofer, and thought that seemed a bit high. What price should I look for for a new woofer? Used woofer? My second question is for after when I get the other woofers so I can have stacked advents. Is there a specific way on how to hook up the wiring for stacked advents? Or does it depend on what type of reciever you have? Also, I guess this makes it three questions, what is the wattage requirement/recommendation for the New Large Advents? Is a reciever that gives 50 watts a danger to the speaker(kind of like what was said ealier)? Thanks for any help, Tyson
