NOTES:
SR Subwoofers are heavy:
The SR104/SR104DVC weighs 24.5 lb. (11.1kg). The SR124/SR124DVC weighs 26.5 lb. (12.0kg).
To adequately support the subwoofer in its enclosure, use 3/4" (19mm) to 1" (25.4mm) MDF for the front baffle.
If you intend to mount your SR Subwoofer with the magnet facing out, ensure that the pilot holes are small and that you use mounting screws with an aggressive thread that will seat the subwoofer securely in the baffle.

2 Ohm Wiring
Two 4 Ohm subwoofers wired in parallel will present a 2 Ohm load. Make sure that your amplifier is 2 Ohm stable when configured in the bridge mode. Consult your amplifi- er’s owner’s manual before wiring in this configuration.
NOTE: In order to make it easy to parallel multiple subwoofers, the two positive terminals are connected together. The same has been done with the negative terminals.
