1. Introduction
The Tannoy B400 is a horn loaded subwoofer with very high output capability
designed to provide maximum low frequency impact in conjunction with Tannoy
Superdual loudspeakers.
Characterised by a tight and “punchy” sound, the B400 adds depth and dramatic
impact to a wide variety of sound reinforcement applications. This powerful
loudspeaker is capable of delivering remarkable sound pressure levels with
extremely low levels of distortion and power compression while maintaining a
uniform frequency response throughout its dynamic range. This makes the B400
capable of consistent intelligibility and tonal quality at any listening level. Its small
,compact size, only 570mm(H) x 555mm(W) x 650mm(D) [22.4”(H) x 21.85”(W) x
25.6” (D)], enables the box to be placed in permanent or portable applications
without being obtrusive.
The rugged cabinet construction utilises 18mm multiple-ply hardwood and features
carrying handles, inserts for castors, optional load certified MAN flying points which
provide a quick and secure flying system, and a top-mounted stand socket that
serves as a base for locating the main full range or mid/high speakers in the air, and
by using 35mm tubing, a tripod can be eliminated.
2. Unpacking
Every Tannoy product is carefully inspected before packing. After unpacking your
B400 please inspect for any exterior physical damage, and save the carton and any
relevant packaging materials in case the loudspeaker again requires packing and
shipping. In the event that damage has been sustained in transit notify your dealer
immediately.
3. Connectors/Cabling
The B400 is fitted with 4-pole Speakon

connectors. Speakon has the following
advantages over EP and XLR type connectors: All termination’s are solderless, this
makes life easier at the time of installation or when field servicing is required.
Contacts will accept 6 sq. mm wire with an outside diameter of up to 15mm and a
current rating of 30 Amps. The pins of the 2 Speakon sockets identified input/output
on the rear of the input panel are paralleled within the enclosure. Tannoy have
adopted the following wiring standard for all Superdual products :-
