SoloX 18 Subwoofer
WIRING
DUAL AMPLIFIERS
If operating the SoloX with two amplifiers you will need to connect one
coil to each amplifier.

ATTENTION!
The SPAIR is a dual voice coil assembly and as such it is very
important that you utilize both voice coils. It may be tempting to use just
one coil to achieve an impedance you want or think that the other coil
can be saved as a ‘spare’ (no pun intended)...please fight both these
urges!
1. The ‘spare’ coil philosophy is flawed because in the event you
damage one coil, it is 99.999% likely that you have damaged the other
coil as well. (in other words...it IS broken dude!)
2. The SoloX/SPAIR was designed to be operated with both voice coils
powered up. If you do not use both coils it will change the
performance characteristics of the driver; especially power handling.
All the power handling specifications given for the SoloX/SPAIR are
with the use of both voice coils. If you utilize only one voice coil you will
decrease the power handling by 50%; half of what we specify in the
SoloX/SPAIR manuals. It will also alter other specifications of the driver
which effect performance and enclosure design.
So as you look through these diagrams for wiring up the SPAIR you
may be saying to yourself: “Hey self...I can’t seem to find an
impedance I like using both coils...I will just use one coil”. Just tell
yourself that is a bad idea and that you should use both coils. Sam and
Sid use both voice coils and so should you.
