Who should consider this model?
Choose the channel position first, then verify the construction. Rectangular in-wall designs, circular ceiling speakers and architectural bass modules have different installation requirements. Architectural subwoofers must be checked against their required amplifier and enclosure guidance. For the KASA500 Amplifier, compare the published cabinet and driver arrangement with your intended dsp subwoofer amplifier role. Avoid selecting it solely because another model in the family suits a different room.
Components and connections
KASA500 is a DSP subwoofer amplifier, not a loudspeaker. Match the supported KEF architectural bass modules, load and operating mode using the manufacturer setup documentation. Confirm input selection, DSP configuration, ventilation and rack dimensions before installation.
Placement and installation
- Verify available cavity depth, cut-out dimensions and supported wall or ceiling thickness before cutting.
- Avoid beams, electrical services, pipes, lights and HVAC routes.
- Check rear-volume or enclosure requirements, wiring access and any required dedicated amplifier.
- Complete a drawing review before the wall or false ceiling is closed.
These are LiveInSmart planning considerations, not a universal manufacturer-approved configuration. Review the exact model manual and the complete room plan before installation.
Reading the specifications in your room
Frequency response and frequency range are different measurements; keep their tolerances and conditions attached. Sensitivity is not an amplifier power rating. Published cabinet depth is not interchangeable with architectural mounting depth. The room, listening distance, furnishings and calibration affect the final result.
