MODE FOUR Cabinet Options
MF280 & MF400 4x12" Cabinets
Countless hours of Research and Development went in to the development of the MF350 and it became clear
at an early stage that special cabinets would be needed to get the most from it.The MF280 (280W) and MF400
(400W) cabinets are the result of this parallel design process.Designed specifically to reproduce the balanced
mid range and huge bottom end that are a pre-requisite for extreme hard rock and nu-metal sounds, these
cabinets feature:
Sonically optimised Celestion loudspeaker designs
Pro-gauge internal wiring
Increased internal volume
The ultra-rugged construction has been underpinned with literally hundreds of hours of extreme endurance
(soak) testing using real life signals in real life conditions.This has assured us that these cabinets are not only
ready for the sonic demands of a high performance head like the MF350, but also the extreme physical abuse
they may receive on the road.
We recommend the MF280A (angled) and B (base) for full stack operation and the MF400A or B for half stack
operation.
Full Stack versus Half Stack
The MODE FOUR cabinets can be used either as a full stack (two cabinets) or half stack (one cabinet)
configuration.The rig you choose is a matter of personal taste and as always when it comes to sound we
recommend you try both to see which suits your style best. Below is a guide to the major attributes of each:
Full Stack:
Enhanced on stage spread.
More ‘cut through’due to accentuated treble and high mids.
Iconic stage presence.
Half Stack:
More controllable spread of sound on stage (especially base type)
Convenient and portable.
Half Stack Options
The MF400A and MF400B are 8 Ohm/400W cabinets specifically voiced for use in half stack configurations with
the Mode Four.
Whether you choose an angled or base half stack configuration is a personal choice between the different tonal
qualities of each set up.
The MF400A (angled) is, in keeping with other angled 4x12" cabinets, tonally more aggressive than the base
option.The angled cabinet is the usual choice for those who want a more prominent upper mid and treble
response that really cuts through in a live situation.
Alternatively, the MF400B (base) delivers a more even mid range with less spread of the aggressive treble
response.Marshall 4x12" base cabinets are more often used by professionals as they have a more focused
bottom end and a smoother mid range and treble response.They are often easier to deal with in terms of sound
reinforcement and monitoring in a live situation.
Cabinet Impedance & Power Handling
When connecting your loudspeaker cabinet(s) to your amplifier always ensure:
The total impedance of the cabinets is equal to, or greater than, the minimum rated impedance of the amplifier.
The total power rating of the cabinets is equal to, or greater than, the rated output power of the amplifier.

4. Ensure all associated equipment is switched off and unplugged from the mains
before connecting or disconnecting the speaker cabinet.
5. Always plug the speaker lead into the speaker cabinet before plugging it into the amplifier.
6. Ensure any associated equipment is switched off and unplugged from the mains in
the event of lightning storms or if unused for long periods of time.
7. Always ensure that the supplied speaker lead is used to connect the speaker cabinet to
associated equipment.
8. Protect the speaker lead from being walked on, pinched or having heavy objects rolled
over it. Ensure the speaker lead is not entangled with any other lead. If a replacement
speaker lead is required please contact your authorised Marshall Dealer.
9. If the speaker cabinet has switchable impedance, please ensure that the correct
impedance is selected and that any associated equipment impedance settings are also
correctly set.
10. If the speaker cabinet has mono/stereo switching capability, ensure that the switch is in the
correct position for the desired operation.
11. Always move or transport speaker cabinets individually.Never attempt to move or
transport speaker cabinets if they have other cabinets or associated equipment stacked on or
under them.
12. Always ensure that the speaker cabinet is on a level surface, whether used or stored
individually, or as a speaker cabinet stack, and/or with associated equipment placed
underneath or on top.
13. Marshall speaker cabinets should only be stacked with compatible Marshall speaker cabinets.
Never attempt to stack another manufacturers speaker cabinet with a Marshall speaker
cabinet. If you are unsure, contact your authorised Marshall Dealer.
