Fisher XP-6 (1966–1968)

A bookshelf speaker system from Fisher's 1960s Heritage Series, produced as part of a broader speaker lineup replacement

Overview

The Fisher XP-6 is a bookshelf speaker system made in the United States from 1966 to 1968. Fisher sold it as the least expensive of three new bookshelf models introduced in that period. It belongs to the Fisher XP series, which gained popularity in the 1960s for good sound in furniture-grade cabinets, and it carried the "Heritage Series" branding. It replaced earlier models like the XP-1A, XP-2A, and XP-4A. Some sources call it a 3-way system. The RC Audio brochure explicitly labels it a "3-way bookshelf speaker system," and that takes precedence.

Design

According to the RC Audio brochure, the XP-6 has high compliance and high efficiency, and archival source material says the same. It is a 3-way design with a 10" woofer and a 3" tweeter with a ceramic magnet, as shown by available repair parts and the official brochure.

Context

The XP-6 was part of a product shift at Fisher, replacing older models like the XP-1A, XP-2A, and XP-4A. US advertising from the era shows it introduced alongside other XP series speakers such as the XP-7 and XP-9. It belonged to a larger family of Heritage Series speakers that included the XP-1, XP-2, XP-4, XP-5, XP-7, XP-9, and XP-10.

Market

Fisher XP-6 speakers turn up on over 400 second-hand hi-fi sites. Repair parts like foam surrounds and original tweeters are available on the aftermarket. Common problems are deteriorated surrounds and damaged voice coils, which often mean restoring the woofer. One eBay listing offered a pair in four payments of $14.13.
