Four-Speaker In-Wall Bundle

This bundle contains four KLH M-8600-W in-wall speakers designed for indoor or outdoor installation. Each unit uses a sealed and tuned two-way design with a 3/4" MDF back box and steel reinforcement. The speakers are sold as singles but packaged together for multi-room or surround setups.

Suits Whole-Home Audio Installs

Buyers planning a distributed audio system or a dedicated home-theatre wall will appreciate the consistent voicing across four identical units. The 8-ohm nominal impedance and 50 W to 275 W amplifier range fit most stereo or multi-channel receivers. Installers needing weather-rated enclosures or wireless streaming should look elsewhere.

Dog-Leg Mounts And Binding Posts Included

Six dog-leg mounting points per speaker simplify retrofit installation without specialised brackets. Five-way binding posts accept bare wire, spades or banana plugs for flexible cabling. The 3.9 mounting depth eases placement in standard stud cavities. No grille paint kit or calibration microphone is supplied.
