Bi-Wiring and Bi-Amping Capabilities

KEF has designed the R3 Meta to accommodate single and dual speaker cables, making bi-wiring or bi-amping straightforward. Two rotary knobs on the speaker allow you to easily disconnect the woofer from the Uni-Q driver, simplifying experimentation with bi-wiring or bi-amping configurations. This flexibility empowers users to fine-tune their audio setup to their preferences.

Bi-Wiring and Bi-Amping Capabilities

The KEF R3 Meta offers bi-wiring and bi-amping capabilities beyond conventional speaker connections. These features give users greater flexibility and control over their audio setup, enhancing performance and customization.


Bi-wiring is a speaker configuration option that involves using separate speaker cables to connect to the speakers’ high-frequency (tweeter) and low-frequency (woofer) terminals. Typically, speakers have a single set of binding posts for both drivers, but bi-wiring allows for a dedicated connection for each driver. This separation can reduce interference and crosstalk between the drivers, improving sound quality.

The R3 Meta simplifies the bi-wiring process by including two rotary knobs on the speaker’s rear panel. These knobs enable users to disconnect the woofer from the Uni-Q driver, converting the speaker into a bi-wire configuration. This ease of use makes it convenient for audio enthusiasts to experiment with bi-wiring and discover its sonic benefits.


Bi-amping takes the concept of bi-wiring a step further by using separate amplifiers for a speaker’s high-frequency and low-frequency drivers. This setup allows for more precise control of each driver’s performance, as the amplifiers can be tailored to their specific requirements. Bi-amping can improve clarity, dynamics, and sound quality, especially in high-end audio systems.

The KEF R3 Meta’s bi-amping capabilities suit users who want to explore advanced audio configurations. The speaker accommodates bi-amping setups without additional adapters or modifications by providing two sets of binding posts for the high and low-frequency drivers.

In summary, the bi-wiring and bi-amping capabilities of the KEF R3 Meta offer users to fine-tune their audio systems and potentially achieve higher levels of audio performance. Whether you’re an audio purist looking for the utmost precision or simply want to experiment with different configurations, these features add versatility to the R3 Meta’s already impressive sonic capabilities.
