Magnatone also built "Remote Speaker" cabinets. These looked identical to the amplifier cabinets with the same grill cloth and emblems, sans amplifier chassis and control panels.
The earliest extension cabinet I've found reference to was in a partial 1955 Magnatone catalog: the Vibra-Amp Model 113 LN came with a remote speaker jack, so it is likely that a matching extension cabinet was available as well. In 1956, the 160 was paired with the No.15 1x15" extension cabinet. By 1959, the No. 12 1x12" cabinet was available and matched to the 190A, 213A, and 250A amplifiers. The No. 16 1x12" cabinet was available and matched to the 260A and 280A and came with a heavy duty speaker. Similar cabinets and designations were likely available in all years through early sixties.
The 1963 catalog listed an RS1 cabinet with a single 8" 14oz. magnet Oxford (same as the M10/M14/M15), and an RS2 cabinet with a single 15" 28oz. magnet speaker. These came with Royalite tops with integrated handles to match the amplifier. Several of the Custom Series amps had external speaker jacks.
These matching 8" speaker RS1 cabinets might have originally been paired with a stereo M15.
In late 1965, Magnatone sold pairs of 2x12" RS4 cabinets with
the M20. The RS4 came with both
red and black Royalite tops that matched the M20.
Also offered was the RS5 2x12" cabinet borrowed from the new Pro Series. Later, in 1966, when the Pro Series changed their cabinet designations to RS-12 and RS-15, the RS4 and RS5's were dropped and the M20 adopted the RS-12 and RS-15. (see Pro Series below).

Special thanks to Fred Corradi for the photos of this MP5 paired with an RS-6 2x-15" cabinet.
Pictured above is a Pro Series MP5 and a RS-6 extension cabinet. The RS-6 was a 2x15" cabinet that was paired with the MP4, MP5, and M20 amplifiers. Also pictured is an original D-2 dolly. The RS-6 was probably replaced by the RS-15.
The RS-12 came with two C12 Jensens, weighted 48 lbs., and sized out at 22"x33"x12". The RS-15 was a behemoth, weighing in at 85 lbs. and stood 48" tall (48h"32"x12"). A large circular disc emblem was affixed to the front of the RS-15 and carried the Magnatone "M". It was turned at an angle so it would look right standing up or laying down (see pics).
