Integrating IBZA6 Using Subwoofers
4.1 Integrating IBZA6 Loudspeakers Systems with Tecnare
Subwoofers
An
IBZA6
loudspeaker system can be deployed in combination with Tecnare's subwoofers
likes a
SW-12
,
SW115
,
SW118M
. These subwoofers can achieve very low frequency response
extending system response appreciably and increasing the overall acoustic power of a system
in the lowest frequencies.
The ideal ratio of IBZA6 loudspeakers to subwoofers depends on the configuration of the
system, the application, and the frequency content of the signal being reproduced.
For most application, a ratio of two IBZA6 for each SW-12 subwoofer and four IBZA6 for
each SW115 or SW-118M subwoofer yield good results in frequency response and headroom.
4.2 Signal Delay
If IBZAs loudspeaker and subwoofers are used in their full-range configuration together DP-
Series Loudspeaker controlled or T-Series Amplifier, use the factory preset setting if they are
co-planar or near to each other.
For other configuration or if they are separated by a great distance it will usually be
necessary to determine the signal delay and polarity setting with a measurement system such
as SMAART audio analyzer.
NOTE: If the subwoofer’s amplifier/DSP Limit LED begins to light before
reaching the required SPL, consider adding more subwoofers to meet the
SPL requirements without exposing the drivers to excessive heat and
excursion.
