The Kramer WM-8P-SUB adds low-frequency output to an installed audio system. It supports low-impedance or transformer-tapped operation and provides connection points for satellite speakers.
WM-8P-SUB Detailed Features
- Add low-frequency support to installed audio. The passive eight-inch subwoofer reinforces the lower part of the audio range. It works with an appropriate external amplifier and satellite speakers in a complete installed sound system.
- Select 8-ohm or distributed-line operation. Support for 8-ohm, 70V, and 100V systems provides installation flexibility. Set the operating mode or transformer tap to match the amplifier and speaker-line design.
- Match the amplifier to the speaker rating. The listed handling is 80W continuous and 120W peak. Use the relevant operating mode and load requirements when selecting amplifier capacity.
- Connect satellite speakers through the integrated crossover. Four 8-ohm satellite outputs and a passive crossover support a combined speaker arrangement. Check the approved satellite configuration and total amplifier load before wiring the system.
- Use the built-in low-pass filtering. A 300Hz passive low-pass crossover directs appropriate low-frequency content to the subwoofer. The side-firing bass-reflex port supports its low-frequency acoustic design.
- Extend a supported subwoofer arrangement. A loop output is provided for daisy-chaining additional WM-8P-SUB units. The resulting load and wiring must remain within the amplifier and product requirements.
- Keep the installed wiring concealed. A recessed side connector compartment and removable cover help organize and conceal cables. The wall bracket and isolation feet provide installation options suited to the room.
- Match the black finish to the room. This listing is for the black enclosure. The acoustically transparent cloth grille and compact wall-mount design help integrate the speaker into a finished interior.
