The XP-7 became a popular speaker at the time, as it was positioned between the much heavier and more expensive XP-9 and the XP-6, which was just below a 3-digit price. The pricing of the XP-7 model allowed customers to enter the high(er)-fidelity market at a price that was closer to the low-end (XP-6) than to the next better model in the product line (XP-9).
You found this speaker? Clean it!
We frequently receive images of old, dusty speakers that some lucky owner found in his or her garage after decades of storage. Others purchased an old set of speakers for little money at a garage sale. Our advice: Don´t let them deteriorate, but also don´t scratch them with the wrong tools.
Instead: Clean them carefully. Get a set of soft brushes and other cleaning utensils. If the wooden speaker cabinets look dull or out of color (e.g. due to sunlight), give the wood some new life:
1. wipe off the dust . 2. take a very fine sandpaper (1000 Grit and finer) and to sand down the wood. 3. Use an oil finish, ideally "natural" to maintain the original wood color, such as Tried and True danish Oil.
Fisher XP-7 FeaturesThe Fisher XP-7 had been on the market from 1966 to 1969. It’s still around and frequently being restored. While there are newer models of the same speaker on the market (XP-7b and XP-7c), this one has still been the go-to speaker for a number of years. It is a three-way speaker system that contained a total of four speakers housed inside of two mid-range units and then sealed into sub-enclosures. With dimensions of 14" x 24 1/2" x 12" the XP-7 is one of the heavier speakers at approximately 45 pounds. It had a free-piston design as well as two five-inch mid-range speakers that were sealed into separate sub-enclosures. AcoustiGlas was used to fill the enclosures. The drivers are encased in a walnut cabinet with a brass grill.

Most noteworthy is probably that the XP-7 is a 4-speaker threeway system and the XP-7b and XP-7c are 5-speaker fourway systems. All of the three speakers have a 12 inch bass driver, but whereas the XP-7 has two identical 5" midrange drivers, the XP-7b and 7c have two 5 3/4" midrange drivers, one for the lower midrange and one for the upper midrange. At last, the Xp-7b and 7c have two 3" tweeters, instead of the 1 1/2" soft dome tweeter of the XP-7. The introductory prices of the three models were: XP-7: $139.50; XP-7b: $149.50; XP-7c: $169.95.
Differences of the XP-7, XP-7b and XP-7c summed up:
- 1966-69: XP-7 12" / 5" (2) / soft-dome tweeter; 3-way; 30-20,000 Hz; 50 watts; 45 lbs;

Fisher XP-7 Strengths and WeaknessesThere are a lot of strengths when it comes to the Fisher XP-7. It housed four speakers that were able to create a frequency response of 30-20,000 cps. The open air resonance of the bass speaker was 18-20 cps and the crossover frequencies of the treble speaker were 300 and 2500 cps. It is commonly

The main weakness lies on the fact that older Fisher XP-7 speakers are sometimes in fairly bad shape and need repairs. This means that you have to know a little something about the speakers if you want to get them up and running. The 12-inch woofer doesn’t come out easily, which means it may happen that you damage the cabinet in order to get it out. If you enjoy spending a little work on an old pair of speakers, the XP-7 can be a nice project.
