came accross your post in a thread abut some jensen speakers. i am trying to find out more nfo about a set i have and hoped you might be able to shed some light on them. The internet was been a waste land of info on them. They are a pair of Jensen Spectrum 550. I need to replace the mid and high frequency conrtols on them, a speaker or two and the cone on a woofer. They sound awsome, big and loud, but not nearly as good as they coul.
