Reference RSH Subwwofer - Rich bass – no compromises!
MB QUART proudly releases the newly developed
RSH shallow mount subwoofers. With their ultra-
slim design, solid, fiberglass-reinforced composite
baskets and a powerful neodymium magnet system
mounted on the front. The RSH subwoofers
bring uncompromisingly powerful
bass reproduction to car audio,
even in applications where the
space available really leaves no
room for subwoofers! The sub-
woofers of the RSH series have
been designed for small and compact
enclosures.
Subwoofer basket made of glass-fiber reinforced injection molded plastic with extreme shallow
mounting feature for optimized installation
Multi-Neodymium stacking dual center plate motor reversed on top of the cone
Dual 4 Ohm 2.5” (64 mm) voice coil on glass fiber former with an aluminum reinforcement neck
Injection polypropylene fill thick body form for maximum damping and structural rigidity
¾”/ (20 mm) tall NBR rubber surround for more cone area and excursion
Single flat poly cotton spider with woven tinsel lead wire
Custom nickel plated push type terminals
The brand-new RAB amplifiers of the Reference-Line
are characterised by an extremely compact housing,
outstanding performance and absolutely infinite va-
riability. When it comes to designing a car hi-fi sys-
tem with restricted space availability, the amplifiers
of the RAB series simply have to be the first choice.
Nothing available today provides this level of power
in such a small chassis. An RAB amplifier can easily
be mounted under a seat or behind a panel to provide
that extra output in locations where other amplifiers
simply won’t fit.
Space-Saving focused mass aluminum heat sink
