5-Pair In-Wall Speaker Kit

This bundle supplies five pairs of Legrand MS3651 3000 Series 6.5" in-wall speakers together with five pairs of KLH WK-6600 installation kits for Faraday Series F-6600-W speakers. It is designed for installers and homeowners building a whole-house music distribution system. The package delivers everything needed for a coordinated multi-room audio deployment in new construction.

60–20 kHz Frequency Response

Each Legrand speaker covers a frequency range of 60 to 20 K Hz with a sensitivity of 50 and a nominal impedance of 6 ohms. These electrical characteristics determine amplifier compatibility and the achievable listening levels across every zone. Matching the amplifier to these specifications is the single factor that decides whether the system performs as intended.

Pre-Construction Brackets Included

The KLH WK-6600 kits provide pre-construction brackets that secure speaker locations before drywall is fitted. This eliminates retrofitting work and guarantees precise cut-out alignment for the Faraday Series F-6600-W models. The brackets turn a multi-room rough-in into a repeatable, labour-saving process for the installation crew.

Questions about this item

How loud will the 60 to 20 K Hz speakers play in a typical room?

With 50 sensitivity and 6 ohm impedance, these 6.5 inch drivers deliver clear output for background music across multiple rooms when paired with a suitable amplifier.

What does the 6 ohm impedance mean for amplifier matching?

The 6 ohm load is compatible with most home amplifiers rated for 4 to 8 ohms, allowing flexible integration into whole-house audio systems without special matching.

What wall cavity depth does the WK-6600 kit require?

The pre-construction brackets mount between standard studs, positioning the F-6600-W speakers flush with the finished wall surface for a clean installation.
