Slim Trim Grille

The flat, magnetic, minimum bezel grille gives a modern, premium, and – most of all – discreet look for great sound anywhere in the home without being obtrusive to the eye or interruptive of the design of the listening area. Square and round grilles are included to match any style.

For increased mounting flexibility and pre-install marking during new construction.

Our Review

The Klipsch SLM-3400-C is great for anyone short on ceiling space but not willing to compromise on sound. With its ultra-slim 50 mm depth and fully enclosed fire-rated back box, its designed to slip neatly into tight spots while still delivering that unmistakable Klipsch punch. The 4 IMG woofer and 1 aluminium dome tweeter, paired with a custom Tractrix horn, produce surprisingly full-bodied bass and crisp, lively highs – perfect for bringing life to background music or cinematic effects. The magnetic Slim Trim grille sits flush and discreet, blending beautifully into your ceiling whether you opt for the round or square design. Its all the premium performance youd expect from the Klipsch Reference series, just in a sleeker, smarter package.
