Above, The sound from the speaker at point A takes 87ms to
reach the speaker at point B
will offer narrower dispersion in the vertical plane. By tilting
the speaker, the sound reaching the ceiling is further reduced and concentrated onto the congregation. In addition, the volume of the sound no longer reduces in
accordance with the inverse square law, the speakers can
project sound over much longer distances meaning fewer
zones or no zones at all!
Mounting the speaker at an angle can be obtrusive. By
Controlling the signal to each driver in the column, the
sound beam can be steered and focused onto the congregation whilst the speaker remains in a vertical position.
An aesthetically pleasing acoustic Solution for highly
reverberant environments.
Unfortunately, the challenge is not complete. With multiple speaker drivers, zones, time delays and possibly beam
steering, instead of a small twin core cable daisy chained
to connect each speaker, a large multicore cable connecting each speaker back to the control room is required. Not
only is this expensive to install, in listed buildings with
stone and decorative plaster work it may not even be
permitted
The soundscape has been improved but nothing has been
done to tackle the fundamental issue of long reverberation
times typically caused by the high ceilings with reflective
surfaces. Acoustic tiles and other physical remedies could
be used to dampen the reflections, but there would detract
from the aesthetic and impede the musical richness of the
space. Instead we turn to column speakers. Long thin, these
elegant speakers easily blend into the architecture of a highceilinged venue and, by nature of their construction, dispersion in the vertical plane is restricted; a longer column
Fulgor Services are the only manufacturer providing a
solution; steerable column speakers with power, signal and
control all on a twin core cable.
UnivoxAudio Ltd is a specialist AV distribution company for the UK and Ireland.
We support a small number of manufacturers whom we believe offer something different, something special.
They are: Bo Edin, Fulgor Services and Okayo
Unlike many distributors, we aim to have a technical understanding of the products we support second only to the
manufacturer but we don't like keeping it to ourselves.
If you have
the time, we will train you, not in our products,
but in the technology enabling you to make informed choices. If you don't have the time, then we will help you design
and specify the most cost effective solution.
