I have a pair of Lynnfield 500 speakers - made by Boston Acoustics - that I inherited from my father who bought them in 1997. When he passed away I got them. He had them Bi-amped with a pair of B&K power amps.\nNow I want to hook them up to my Anthem 500 Surround receiver.\nTo make sure I was doing things right, I started looking for the Lynnfield 500 manual on line.\nNothing there.\nThen I went to Boston Acoustics site since the speakers were made by them but were discontinued back in 1997.\nNo help there.\nNext, I called them and there is a guy looking around for a manual but have not heard back from him.\nI thought I would try here to see if anyone can help me.\nHere is my problem....\nI cannot get the lower units to work.\nThe upper units with the mid and tweeters work fine.\nThe lower units have three terminals. One labelled :woofers, one labelled mid-range and one labelled tweeters.\nIt is obvious that if you are using a single source to power the speakers, you would need to link the terminals in some way.\nI do not have those parts.\nBut when I hook the woofer's terminals to an amplifier - as if I was bi-amping them - I get nothing.\nI wonder why that is. How could they have both been blown up?\nDoes anyone out there have a manual for these speakers so that I can see how the lower unit gets hooked up properly before I start taking the speakers apart and looking for replacement parts?\nIf my worst scenario is true I think the crossover device for the lower unit is gone but I need some help here as I am way out of my league and can't seem to find anything about them except for a few reviews.\nAny help or ideas on how to get help would be very much appreciated.
