Powerful Flagship for Music and Home Theater

The R11 Meta is the largest floor-standing model in the R Series and was designed to create a stunning listening experience. It is ideal for use in high-end stereo systems or as a central element in a versatile home theater setup, reproducing both fine details of a recording and raw power and agility.

Outstanding Acoustics Through Innovative Technology

Based on technological innovations from the Reference Series, the speaker utilizes Metamaterial Absorption Technology (MAT™). This absorbs 99% of unwanted sound from the rear of the driver, resulting in particularly pure and natural sound. The 12th generation Uni-Q® driver array acts as a point source, enlarging the optimal listening area ("sweet spot") and distributing sound evenly throughout the room.

Precise Low-Frequency Reproduction and Dynamics

Four 165mm hybrid aluminum woofers provide a powerful foundation. These allow for greater excursion and deliver tight, deep, and controlled bass. In combination with the three-way bass reflex design, a dynamic soundscape is created, reaching down to low frequencies of 26 Hz (typical in-room response).

Functional Design and High-Quality Craftsmanship

The speaker is equipped with special microfiber grilles. Each grille has 1801 precisely laser-cut holes per driver, ensuring acoustic performance even with covered drivers.

Award-Winning Sound Concept

The acoustic performance of the series has received multiple awards, including "EISA Loudspeaker Series 2023 - 2024". Industry media praise the flawless interplay of controlled lows and far-reaching, open highs, as well as the solid build quality.
