JBL Speaker Compatibility & Fitment Guide
This premium 4.5-inch foam surround repair kit (Model 4.5F#1) is sized specifically for the woofer in the JBL Control One family of compact monitors. Replacing perished foam corrects the rattle and loss of bass these speakers develop with age, and restores the original acoustic balance.
JBL Control One Series
- Control One: Control One, Control 1, ControlOne
- Variants: Control 1C, Control 1G, Control SB1, Control 1SE
Enough for one pair of speakers — two surrounds, one per woofer.
