Quick answer
To set up your PS Audio Foundation System with the Stacking Kit for Subwoofer Pair, follow the ordered steps below to safely stack and integrate dual subwoofers for improved bass response.
Foundation System
Why stack subwoofers?
Stacking a pair of subwoofers can reduce floor space usage and, in some rooms, improve bass coupling by placing the drivers closer together. However, this approach may limit the ability to spread bass evenly across the room compared to placing them separately. The PS Audio Stacking Kit is designed specifically for this purpose, ensuring a stable and secure connection between the two subwoofers.
Choosing the right Foundation System configuration
The Foundation System is available with various finish and AirLens options. Before stacking, ensure your subwoofers are compatible with the stacking kit. The kit is a single Standard option under SKU FDY-STACK-KIT, so no additional configuration is needed beyond your initial Foundation System order.
Step-by-step stacking instructions
- Prepare the subwoofers: Place both subwoofers on a clean, level surface. Remove any packaging materials and ensure the bottom subwoofer is positioned on a stable, non-slip surface. Common mistake: stacking on carpet without a rigid base can cause instability. Check that the bottom subwoofer is on a firm, level base.
- Attach the stacking kit: Align the stacking kit brackets with the mounting points on the bottom subwoofer's top panel. Secure the brackets using the provided screws, tightening them firmly but not over-torquing. Common mistake: using incorrect screw alignment can damage the threads. Verify the bracket alignment before tightening.
- Position the top subwoofer: Carefully lift the second subwoofer and lower it onto the stacking kit brackets, ensuring it sits flush and centered. The brackets should engage with the bottom of the top subwoofer. Common mistake: dropping the subwoofer onto the brackets can misalign them. Lower the top subwoofer gently to avoid misalignment.
- Secure the top subwoofer: Use the remaining screws to fasten the top subwoofer to the stacking kit from the underside or as per the kit's instructions. Ensure both subwoofers are securely connected. Common mistake: leaving screws loose can cause rattling during playback. Tighten all screws evenly to prevent vibration.
- Connect and integrate: Connect the subwoofers to your audio system using appropriate cables. For bass integration, set the crossover frequency on both subwoofers to match your main speakers. Common mistake: setting different crossover points can cause phase cancellation. Match crossover settings on both subwoofers for coherent bass.
- Test and adjust placement: Play a bass-heavy track and listen for even bass response in your listening position. If bass is boomy or uneven, try moving the stacked pair slightly in the room. Common mistake: placing the stack in a corner can exaggerate room modes. Experiment with placement within a few inches to optimize response.
