The lower crossover point (1000hz) was for the Original Advent. The Advent with the higher crossover point was for the New Advent Loudspeaker which I believe came around approx. 1975 or 1976. The physical difference between the two is the original had all squared off corners. The front of the New Advent had rounded corners and front edges. I also believe they started using ferro-fluid "fried egg" orange tweets in the new version. The reason for upping the x-over point in the New was to stop blowing out the tweeters. People who had the old version were burning out tweeters with excessive power input and usually with rock music of the time. Advent addressed the problem with the higher crossover point and ferro-fluid (for cooling of the magnetic gap in the tweeter). This in turn gave the tweeter extended life but unfortunately narrowed the high frequency radiation patterns which many people found fault with. I have tried to be as accurate as possible about this, but it was from an article I read many, many years ago. I apologize for any inaccuracies.
What's the scoop on the old Jensen Corp "Advent" speaker by H. Kloss?
I have recently come into a pair of these grand old speakers that feature the 'fried egg' orange tweeters that were once a big hit. They also have a switch to change power or drive attached to each one. I would like to know everything about these before I tear them apart to reuse the cabinets.
Any and all information will be appreciated.
