quality, fully insulated speaker cables made of stranded copper wire.
In order to preserve a high damping factor it is desirable to keep loudspeaker cables as short as possible and

with a gauge offering low resistance per unit length.
The following table provides information regarding the recommended cable length versus conductor cross-section.
Two cases are possible depending on the impedance load connected to the LA4 or LA8 (8
enclosure, 4
for two SB18 enclosures in parallel):

According to the calculation in Table 2, a DO25/DOSUB-LA8 cable combination can be used to power two SB18 in
parallel (4
