6.4 Bass alignment - delay times
Note: All information given here is a guide and not a rule. Taking measurement on
site and using your ear are still the most reliable way to achieve the best results.

Figure 6.14 shows a second low frequency
enclosure added. Here we are looking to create
a secondary focal point at E. To calculate our
delay time we take distance D, which is point
E to the south edge of the circle, away from A,
which is E to the north edge of the circle, and
multiply by the delay time per metre. Or:
(A - D) x 2.9 ms/m = delay time.

6 System design
All four loudspeakers sit on a circle of radius R
with its centre point at O. The low frequency
enclosure is situated at a distance A from the
origin and a distance B from the circumference
of the circle. The distance B will determine the
delay required for the low frequency enclosure
of 2.9 ms per metre. So, in this example, if the
distance B is 2 m the a delay of 5.8 ms would be
required.
When designing loudspeakers and low frequency
enclosures layout within a space it is often
necessary to apply delay to optimise system
performance. In figure 6.12 we have a room
with four Venu V2 loudspeakers and single low
frequency enclosure.
