Extron BCK SF 26CT LP (part number 70-1283-01) — low-profile plenum-rated back can pair for the SF 26CT LP two-way ceiling speaker, sold without the driver assembly.

The BCK SF 26CT LP swaps in a shallower 4.72" back can where plenum clearance is too tight for the standard SF 26CT enclosure, while still accepting the same DAK SF 26CT LP driver assembly kit to become a complete speaker. Buying the can separately supports staged installs, rough-in ahead of driver delivery, or replacing a damaged enclosure without touching the driver.
