Marshall Model 1991 P.A. Column Cabinet
Compact, efficient, and purpose-built for live sound, the Marshall Model 1991 P.A. column cabinet was introduced as a practical solution for small to mid-sized venues. Designed with portability and clarity in mind, it brought Marshall’s signature quality to the growing market for modular P.A. systems in the early 1970s.

Technical Overview
Each Model 1991 cabinet contains:
4 x 10-inch Celestion speakers
With a total power handling capacity of 50 watts per column, the 1991 was ideally suited for use with Marshall’s 50-watt P.A. amplifiers, such as the Model 1985 or Model 1963, as well as the 50-watt Master P.A. Model 2002. The 10" drivers offered a fast, focused response—perfect for vocal clarity, speech, and acoustic instrument reinforcement.
The smaller cone size compared to 12" speakers also helped reduce unwanted boominess and provided greater high-frequency articulation.
Dimensions and Design
As listed in the May 1971 catalog, each 1991 cabinet measured:
Height: 48 inches (121.90 cm)
Width: 14 inches (35.56 cm)
Depth: 10 inches (25.40 cm)
The tall, narrow cabinet shape was optimized for vertical dispersion, projecting clear sound evenly across a crowd or room without taking up valuable floor space. Its modularity made it easy to transport, stack, or place discreetly on either side of a stage setup.
Usage and Pairings
The 1991 was featured in several factory-recommended setups, including:
50-watt P.A. Set-Up No. 50PA/4 – with Master P.A. Model 2002
50PA/5 – with 8-input Model 1963 P.A. amplifier
50PA/6 – with 4-input Model 1985 P.A. amplifier
Each setup leveraged the column’s balance of compact size and vocal-friendly tonal response, allowing small groups, venues, and rehearsal spaces to achieve professional-level clarity at manageable volume levels.
Construction and Durability
The cabinet was constructed from seasoned wood, and finished in black vinyl. Marshall also supplied:
Two 21' speaker leads
Waterproof protective covers
Though not as large or powerful as the 1969 or 1976, the 1991 made up for it with reliability and ease of use—a trusted column for vocal reinforcement that performed well beyond its modest footprint.
Collector Insight
While the 1991 isn’t as flashy as Marshall’s guitar cabinets, it holds a special place in the brand’s live sound legacy. Original units with Celestion 10" drivers and unmodified cabinets are rare, and highly desirable for collectors piecing together early Marshall P.A. systems or restoring vintage live rigs.
