165 WR 26 90 CD
4 ohm -
Order ID: 830513
A 6½" CD woofer with extra high efficiency due to the very heavy magnet. When
using the supplied clamps the 830513 fits into car standard mounting holes in
the doors as well as in the parcel shelf. Peerless' unique injection moulded
"cast" diaphragm secures superior performance.
