Bundle contents

This package combines four KLH WK-6600 installation kits with four Legrand MS3651 3000 Series 6.5 in-wall speaker pairs. The kits are built for Faraday Series F-6600-W speakers and ship as matched pairs for straightforward mounting. Together they supply eight drivers for distributed audio across multiple rooms.

Upgrade path

The bundle replaces ad-hoc brackets and mismatched drivers with a unified rough-in and speaker system designed for multi-room music distribution. The jump is worth it when a project calls for consistent 60 to 20 K Hz coverage and 6-ohm impedance across several zones without mixing hardware generations.

Installation limits

Each speaker carries a 50 sensitivity rating and 6-ohm load, so amplifier headroom must match that demand across all active zones. The pre-construction brackets fix rough-in positions before drywall, limiting later relocation. RoHS conformance confirms material compliance but does not extend weather protection beyond the indoor/outdoor rating.

  • Four speaker pairs deliver whole-house multi-room audio
  • 5" drivers cover 60 to 20 K Hz frequency range

Questions about this item

What cut-out size does the KLH WK-6600 bracket need for the 6.5" Legrand MS3651 speakers?

The pre-construction bracket is built for 6.5" drivers, so cut the drywall to the 6.5" diameter specified for the Legrand MS3651 pair.

Which step do installers most often miss when mounting the WK-6600 kit before drywall goes up?

Securing the bracket to the studs with the supplied screws before hanging drywall; skipping this leaves the speaker with no solid anchor.

How often should the Legrand MS3651 3000 Series drivers be checked after installation?

Inspect the 6-ohm drivers once a year for dust on the cones and verify the 60-to-20 K Hz response remains clean.
