MB Quart FKB168 Formula 5"x7" / 6"x8" 2-way Coaxial Car Audio Speakers (Pair)

 MB Quart Formula 5×7 / 6×8 inch 2-way coaxial car speakers
with aluminum dome tweeters and Butyl rubber surrounds.

 Tweeters. Aluminum dome tweeters deliver great sound with
increased reliability.

Cone Material. Lightweight thermal-formed polypropylene
cones enable faster midrange response.

Surround / Cone Coupling. Butyl rubber surrounds provide
durability and deeper mid-bass impact. The cone/surround connection utilizes a
high temp adhesive which assure the cone and surround do not separate in high
power uses or extremes of weather.

Gasket. A textured ABS gasket assures a rigid linear seal to
the mounting surface.

​Voice Coil / Former Assembly. Pure Copper voice coil
creates a strong magnetic field with a very thin extrusion. Kapton voice coil
former is lightweight and efficiently dissipates heat.

Spider. Natural fiber allows flexibility while the infused
epoxy gives strength during the manufacturing process.

Cooling System. Over-coil cooling system allows air exchange
over the voice coil through the spider

Crossover. 6dB internal crossover integrated into the design
to assure smooth midrange to tweeter frequency transitions.

Frame. Heavy gauge progressive-die stamped steel frames for
ultimate rigidity.

Motor. Ferrite magnt motor creates a strong magnetic field
while remaining small enough to fit nearly every application.

Connectors. Use spade connectors or solder direct for the
best connection. Tinsel Leads: Highly conductive while remaining flexible
during high power applications.
