Marshall MF400B

Marshall MF400B Mode Four 4x12 Straight Cabinet 400 Watt
The MF280 (280W) and MF400 (400W) cabinets are specially engineered to reproduce the balanced mid range and huge bottom end that are a pre-requisite for extreme hard rock and nu-metal sounds. In keeping with all legendary Marshall cabinets the MF 4x12" 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. Marshall recommends the MF280A (angled) and B (base) for full stack operation and the MF400A or B for half stack operation. MF280A Cabinet: 280 Watt, 16 Ohm, mono, angled-front 4x12” cabinet loaded with four, custom-voiced 70 Watt 12” Celestion/Marshall “Vintage 30MF” speakers. MF400B Cabinet: 400 Watt, 8 Ohm, mono, straight-front, 4x12” cabinet loaded with four custom-voiced 100 Watt, 12” Celestion/Marshall speakers.

Size Does Matter!

To ensure optimum performance of the MODE FOUR, four complimentary 4x12” cabinets were designed – two angled and two straight. The first thing that strikes you about these cabinets is that they’re a good three inches taller than Marshall’s regular 4x12”s. Even though this makes a MODE FOUR stack incredibly impressive and imposing, it wasn’t done for aesthetics – it was done for tonal reasons. By making the cabinets bigger, the resonant frequency of each one is lowered. When combined specially designed Celestion speakers, this enhances and compliments the extra bottom-end capabilities of the MODE FOUR head.

Marshall has also investigated the effect of the relative positioning of the speakers within a cabinet and found that by moving them around they were able to fine tune the mids and, to a lesser degree, the lows, for optimum performance. Marshall also increased the thickness of the cabinet’s plywood back to control vibrations created by the high-pressure levels inside the cabinet.

The Celestion speaker that came closest to the desired full-stack tone was the renowned “Vintage30”. By working closely with Celestion, as Marshall has for the past four decades, the engineers used this speaker as a starting point and developed the Vintage30MF, a 12”, 70 Watt speaker that delivers a full, punchy “in your face sound.” This exclusive speaker is fitted into the 280 Watt, 16 Ohm MF280A (angled) and MF280B (straight) cabinets.

Market research has shown a growing number of guitarists only use a single cabinet, half stack set-up. To cater to them Marshall also designed a pair of 400 Watt, 8 Ohm cabinets – the MF400A (angled) and MF400B (straight) – that can handle the 350 Watts which the MODE FOUR delivers at 8 Ohms. The perfect speaker for both was found to be the Celestion G12K-100, a 12” speakers that produces a rich, well-balanced tone.

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
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.
