Bundle contents

This bundle pairs a KLH WK-6600 installation kit with a pair of Legrand MS3651 3000 Series 6.5-inch in-wall speakers. The kit is designed for Faraday Series F-6600-W speakers, while the Legrand units target multi-room audio distribution in residential settings. Both components are new and RoHS conformant.

Upgrade path

The Legrand speakers replace basic in-ceiling or bookshelf units when a builder wants flush-mount stereo sound with 60 to 20 K Hz frequency response and 6-ohm impedance. The jump is worthwhile when the project calls for pre-construction brackets that lock speaker position before drywall goes up.

Installation limits

The WK-6600 brackets only accept Faraday Series F-6600-W models, so they cannot be reused for other speaker lines. The Legrand pair is rated for indoor and outdoor use but lacks weatherproofing specs beyond the general type designation. Sensitivity is listed as 50.

Questions about this item

Does the KLH WK-6600 kit fit the Legrand MS3651 6.5" speakers or only the Faraday F-6600-W?

The WK-6600 kit is designed for Faraday Series F-6600-W speakers; it is not confirmed for the Legrand MS3651 6.5" units.

What is the correct order — mount the pre-construction bracket first, then wire, then snap in the speaker?

Secure the pre-construction bracket to studs before drywall, pull speaker wire through the opening, then attach the Legrand MS3651 speakers after the wall is finished.

Will the 6-ohm Legrand MS3651 drivers need a different amplifier setting than 8-ohm models?

Yes, set your amplifier or receiver to the 6-ohm position so the 6-ohm Legrand MS3651 speakers operate within their rated impedance.
