9.4 Stacking speakers on top of a subwoofer
with the CRF-PB pull-back frame
Heads up: Never stack more than three COSMO C 8s
on the ground using the CRF-PB.
1
Slide the C-M20 sub-adapter into the CRF-PB's keyhole rail using
the groove as a guide.
2
Set the CRF-PB on the CS 118 or CS 218; then screw the C-M20
sub-adapter into the subwoofer's M20 threaded insert. The pre-
tensioning, due to screwing the adapter into the sub's threaded
sleeve, affi
xes the CRF-PB to the top of the subwoofer.
3
Attach the COSMO M/H unit to the CRF-PB pull-back frame.
4
You can set the M/H unit's angle on the CRF-PB to –5°, –3°, 0°,
