Speaker 8" inch 16 ohm 8527-722 Full Range Radio loudspeaker Vintage 1970s

Description

FULLY TESTED!
Nice vintage
full range speaker driver unbranded
model
8527-722
. Official size is 8 inches. Cross holes measurement is 7 3/4"(diagonal c/c fixation hole measurement). Thickness is 3 3/4". This speaker is from the 1970s most probably. Output power is typically around 5 watts for this format and have a measured coil resistance of 16ohm. Tested with a low power PA amplifier and
sound is excellent and appropriated for this type of speaker.
FULLY TESTED
All my Speaker drivers are tested with music at the proper impedance setting using a multiple impedance output PA amplifier from radio shack and a FLAC music player on AUX. My criteria is simple, to hear a nice clean sound with no distortion or scratchy sound due to defective voice coil or impurities accumulated on magnet, or due to any cone issues. The type of sound a driver delivers is not considered in the
analyze
as there are many types of sound depending of many construction aspect (IE: less bass/treble) and it's uses. One of the photos with listing may show the driver under test (if there are wires connected).

IMPORTANT INFORMATION
when ordering a replacement speaker:
If you're looking for a replacement speaker, the first important thing to look for is the size in length. If you want to replace a 4 inch speaker in a device, look for this size first and shape type (round, square). See as well the measurement of the fixation holes (when
equipped
) as it have to be re-installed properly. Then the 2nd important data is the impedance. If it's 4 ohm, look first for a 4 ohm. If none available, choose 3.2 ohm or 6 ohm at max but ideally, use the same impedance (not 8 or 16 ohm to replace a 4 ohm). 3rd, it's watt output rating. This is not a must in some case, mainly for a TV or a Radio replacement speaker but the nearest value will give the best result. Don't choose either too low (it may fried the speaker coil) or too high (speaker will not vibrate enough). A 1 to 2 watt speaker would be fine to replace a 1 Watt speaker for example. And finally, it's thickness. This will be an important factor when the speaker is located in a restricted area. If you have 2 inches available, then go below this measurement to be sure it will fit.
