2. GENERAL DESCRIPTION AND FEATURES
The BS-678BSB and BS-678BSW are certified according to the European Standard EN 54-24: 2008, the
International Standard ISO 7240-24: 2010 and compliant with the British Standard BS 5839-8: 2008 14-8.
• The BS-678BSB and BS-678BSW, of which cabinet is made of wood, can be installed in a vertical or
horizontal orientation.
• Either concealed in-wall wiring or open wiring can be used for speaker cable connection.
• The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily
even if an outward force is applied to.
• The input impedance can be easily changed by changing the tap position of the transformer.
• A 6.5-inch cone speaker unit delivers high quality sound.
• Two screw terminals (steatite) make cable connections easy and allow bridge wiring.

be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
• Do not use anti-rust lubricant. If it contacts resin or
rubber parts, they could deteriorate and cause the
speaker to fall, possibly resulting in personal injury.
• Do not install the speaker in indoor swimming pools
or such locations where liquid chemicals are used.
The parts deteriorate if corroded, causing the
speaker to fall, which could result in personal
injury.
When the Unit is in Use
• If any of the following irregularities occurs,
immediately switch off the amplifier's power, and
inform the shop from where the speaker was
purchased. Further using the speaker may result in
fire or electric shock.
· If you detect smoke or a strange smell coming
from the speaker
· If water or any metallic object gets into the
speaker
· If the speaker falls, or the speaker case breaks
• To prevent a fire or electric shock, never open nor
remove the speaker case. Refer all servicing to
your nearest TOA dealer.
When Installing the Unit
• Avoid touching the speaker's sharp metal edge to
prevent injury.
• To avoid electric shocks, be sure to switch off the
amplifier's power when connecting speakers.
When the Unit is in Use
• Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to heat, resulting in a fire.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or the
mounts that could cause it to fall, possibly causing
personal injury.
