TECHNICAL SPECIFICATIONS FOR DLS REFERENCE SUBWOOFERS
RECOMMENDED ENCLOSURES FOR RW15
VENTED ENCLOSURE
SEALED ENCLOSURE
The speaker is installed in Vb1
playing into chamber Vb2 where
the port(s) are installed.
F3
= approximative lower frequency for
vented boxes in Hz. Often called F-3 dB point
= the point where the power is 50% lower.
Fb
= Box resonant frequency
SEALED BANDPASS
Vb1=rear chamber
Vb2=front chamber
RUNNING-IN PERIOD
Allow the speaker to play for at least
15-20 hours. After this time the
performance is correct.

CALCULATE YOUR ENCLOSURE
Box volumes:
When caculating the volume of an enclosure you simply
multiply the width (W) x heigth (H) x depth (D).
Use measures in dm and you will get the answer in
liters.
A trapezoid box is calulated as below:
Vol=width (W) x heigth (H) x upper depth (UD) + lower depth (LD)
