The TK4-SA-PP toe kick mounts in the ceiling like any other SA speaker and connects to any recommended PowerPipe subwoofer which has a 4" tube. A full range of trim kits allow the visual to match all of the SA series and can be found under the "Accessories" tab

Due to the higher air port velocities of 10" and 12" PowerPipe models, we recommend the 650PTM and 800PTM for this application to eliminate possible port noise at high levels.
