Connections
For the best sound quality and signal transfer, AV123 recommends a minimum of 16
gauge high quality, multi stranded, oxygen free copper speaker cables if using the
speaker level inputs on MFW-15. For preamp level connections, use high quality, oxygen
free copper audio cables.
MFW-15 Subwoofer Connections
Although there is technically no connection necessary to the driver itself (we’ve already
done that part) you do have to choose connections for the audio input to the x-sub
subwoofer. There are several ways in which to accomplish this:
Speaker Level Inputs
In situations where a line level out from your receiver or pre-
amp is not available, we recommend the following method
for connecting the x-sub or x-pls:
1) Connect the monitor or tower speakers directly to the
amplier outputs (both left and right channels).
2) Next, connect a second pair of speaker wires from each
monitor to the high level input on the x-sub or x-pls.
The high level input allows speaker level signals for signal input
and sums the left and right channels to a mixed mono input so
the sub remains active whether balance is moved from left to
right. By directly wiring the montiors or towers to the amplier,
the bottom octaves blend smoother with the output.
Line Level Inputs
If your receiver or preamplier has a set of full range RCA line
outputs that are not already being used, you can connect these
into the LEFT and RIGHT Line Input jacks (pictured at right
in the illustration). When using these inputs, the crossover is
still active so a full range input will be ltered to allow only
the lowest frequencies to reach the subwoofer. There are
no line outputs on the x-sub so if there are multiple devices
needing an input from only a single RCA preamp output on
your preamplier or receiver, you can use “Y adapters” to split
the output. We do not recommend splitting it to more than two
devices and both should have relatively high input impedances
(20k Ohm or higher) so there is no signicant signal loss.
