Hardware matched to the cabinets
The kit includes two brackets, eight thumbscrews, and a 2.5 mm Allen key. Follow the illustrated instructions to position and fasten the subwoofers securely. This is model-specific hardware, so use it with the Foundry F12 rather than assuming compatibility with another cabinet.

Connect the pair as described
The included XLR cable connects the lower subwoofer’s Sub Out to the upper subwoofer’s XLR In according to the guide. Complete the mechanical installation before configuring the connected system.
