There are two new members of Pioneer's premier speaker family. The S-4EX-W, the smaller bookshelf model in the photo, and the smaller center channel,the S-8EX-W. (The two floor standers and the subwoofer are not shown here.) The Pioneer rep on hand seemed a bit fuzzy on the prices, but $4,000/pair for the bookshelves and $2100 for the center was his story. All of the speakers, and corresponding in-walls, employ a unique magnesium cone woofer with an integral, coaxially mounted beryllium-dome tweeter. Shipping now.
