Versatile Performance for Music and Home Theater

The R7 Meta is designed as a mid-sized floorstanding speaker for use in high-quality stereo systems or as part of an immersive home theater setup. It was developed to create a detailed and natural soundstage for both musical performances and film sounds.

Technological Innovations from the Reference Series

The model benefits from a range of technical innovations originally developed for the Reference series. At its core is Metamaterial Absorption Technology (MAT™), which absorbs up to 99% of unwanted sound waves from the rear of the driver to minimize distortion and ensure a purer, more natural sound.

Pinpoint Radiation with Uni-Q® Driver

The 12th generation Uni-Q® driver array acts as a single sound source. This enlarges the optimal listening area ("sweet spot") and allows for even sound distribution throughout the room, maintaining acoustic precision regardless of position.

Precise and Controlled Bass Reproduction

Two 16.5 cm hybrid aluminum woofers provide the low-frequency foundation. These are designed for long excursion and deliver tight, deep, and controlled bass that remains stable even during dynamic passages.

Functional Design and High-Quality Grilles

The included microfiber grilles feature 1801 precisely laser-cut holes per driver. This guarantees full acoustic performance while protecting the technology without negatively affecting the design or sound.

Excellent Sound Quality

The R Series has received multiple awards for its acoustic brilliance, including the EISA Loudspeaker Series 2023-2024. Trade media particularly praise the dynamic and natural sound as well as the first-class craftsmanship of the enclosures.

FAQ

What does Metamaterial Absorption Technology (MAT™) do?
MAT™ is a highly complex, labyrinthine structure that absorbs 99% of unwanted sound from the rear of the tweeter. The result is a purer and more natural sound without the usual distortions.

Can the speakers be operated with grilles?
Yes, the special microfiber grilles feature 1801 precise perforations per driver, ensuring that sound quality is maintained even with the grilles in place.

How flexible is the R7 Meta in terms of placement?
Thanks to the three-way design and the controlled dispersion of the Uni-Q driver, the speaker is very flexible. For fine-tuning the bass, foam bungs (port bungs) for the bass reflex ports are included.
