Little gem: BS 133 JET:
The BS 133 JET is the ideal loudspeaker box for small and mediumsized rooms, up to approx. 50 m². With its compact front dimensions
of 29 x 17.5 cm, it can be built into shelves without difficulty, or can
also be mounted freestanding on the optional LS 70 loudspeaker
stand. With its attractive contours and the deep gloss finish of the
baffle, this loudspeaker will immediately stand out, without taking over
the room. You will be amazed at the scale of sound produced by this
small loudspeaker and its ability to bring out the finest musical detail
Enjoy great music with the BS 133 JET without having to be
surrounded by cumbersome loudspeakers.
Technical features and benefits
Strong drive and a new neodymium magnet system endow the JET
III tweeter with incredible dynamic reserves and a high maximum
output level. A new inner structure, and larger sound apertures, yield
a precise upper cut-off frequency of 50 kHz.
The 140 mm bass driver using ELAC tried-and-tested Aluminium
sandwich technology, allow distortion-free bass response as the
resonance of the membrane is minimised. This is due to the composite
cellulose and aluminium construction.
• Due to the double
flare design of the bass port, flow noise, even at high levels, is
A two-part bass control plug is provided that can partially or fully
close the port, so the system can be adjusted for the room
acoustics and speaker placement.
As the BS 133 JET is magnetically shielded, it can be placed directly next to a
television without affecting the picture quality.
To improve the performance of the system the cabinet is internally reinforced in a
way that eliminates internal standing waves and unwanted resonances.
To optimise the sound there are individual crossover networks for the high and low
frequencies, which can be bi-wired using two pairs of cable or alternatively, for
optimum performance, two amplifiers can be used in a bi-amped situation. Good
contact is guaranteed by large, gold plated speaker terminals, which are fully
insulated to protect against short circuits.
When mounted on the optional LS 70 loudspeaker stand, the BS 133
JET is supported by 3 spikes, which decouple the loudspeaker from the
stands. However, a safety feature of this design insures that the
speaker is secured to the stand while it is in the decoupled mode.
People with pets and small children will appreciate this feature.
