KEF Reference 4C Overview
If you're looking for a pair of center speakers that are truly benchmarks, the KEF Reference 4C Meta is an excellent choice. This model features four bass drivers and a 12th generation Uni-Q driver system with MAT. It's also capable of serving as a left-center-right speaker.
KEF Reference 4C Features
These speakers are lightweight and easy to install. They also have a flexible port design that reduces port resonance. The speaker comes with two different port tube options, so you can alter the sound to fit the room. A computational fluid dynamics simulation was used to calculate the profile and flare of each port, so that the noise created by turbulent air doesn't interfere with the music's sound.
Another feature of the Reference series is the 6.5-inch woofer. It has a dive of 40Hz and is capable of handling the lowest indoor frequency (up to 6dB). It also has a high sensitivity, matching power amplifiers of two hundred and fifty watts.
Designed by audio professionals, the KEF Reference 4 Meta is a benchmark in center speakers. Despite its size, this center speaker features four bass drivers and a 12th-generation Uni-Q driver system with MAT. It can function as a left-center-right speaker, and can also be positioned vertically.
