FKB169 + FKB108

This bundle pairs one set of MB Quart FKB169 6x9" speakers with one set of MB Quart FKB108 3.5" speakers, covering two different factory cutout sizes in the same car without placing two separate orders or hunting for a matching brand later. The FKB169 handles 300W peak power (150W RMS) per pair across 46 Hz to 20 kHz, and the FKB108 handles 140W peak power (70W RMS) per pair across 80 Hz to 20 kHz, so each size is built for the location it fits rather than one speaker stretched across two jobs it was not sized for. Both sets share the same build: an aluminum dome tweeter paired with a thermal-formed polypropylene cone, a butyl rubber surround that holds its shape through hot summers and cold winters, and a pure copper voice coil wound on a Kapton former that sheds heat fast enough for sustained volume. Heavy-gauge stamped steel frames on both sizes keep the cone centered under road vibration, and spade connectors or direct soldering work on either speaker at install. Buying the two sizes together keeps tone matched across the car instead of pairing one aftermarket size with a leftover factory speaker in the other spot.
