These speakers are manufactured in the USA using compact high energy neodymium (NEO) magnets that allow these speakers to fit where others won't. Neodymium magnets (commonly referred to as super magnets) are 1/10 the physical size of round ceramic magnets found on most modern speakers but provide the same or higher field strength. These speakers are true 4 ohm impedance and are fully compatible with the original Delco speaker. The improved construction includes whizzer cones for improved high frequency response and fabric or sanoprene rubber surround and larger spiders for improved low frequency response. They work exceptionally well with original Delco radios and will make your classic radio sound better than new. 5 year warranty against manufacturing defects.
Note:The speaker cone should be displaced in an upward (away from the magnet) direction about 1/8" when a Delco radio is turned on. If the cone moves down toward the magnet, the speaker leads need to be reversed.
