Refoaming Speakers

Back in the 1970s I purchased a pair of Advent-1 loudspeakers. They have served me admirably ever since.

The Advents were designed by Henry Kloss and are considered representative of what was called the East Coast Sound. They are large bookshelf or small floor speakers with a 10" woofer and a dome tweeter-- a two-way design. They sounded and still sound great. Here's a recent (2006) review from Stereophile.

The woofers are the large round components on the bottom. The paper cone is dark gray. The round center cardboard covers the voice coils. The foam rubber surround (outside the dark gray paper cone) is light gray. The surround is glued to the cardboard cones and the outside metal ring and keeps the cones from sagging.
