Product Features

The Revel Concreta B1 is a one-of-a-kind speaker that combines modern technology with a rustic aesthetic. The cabinet is made of concrete, which gives it both strength and a distinct appearance. For clear and detailed sound, the speaker employs a 5.25-inch woofer and a 1-inch tweeter with an integrated waveguide. It also has a rear-firing port for improved bass response.

The Concreta B1 is a small and versatile speaker that can be used as a bookshelf or wall-mounted speaker. The Revel Concreta B1 is a one-of-a-kind and impressive addition to any home audio system, thanks to its combination of modern technology and rugged style.


The 6.5-inch woofer with a coated glass-fiber cone in the Revel-Concreta B1 delivers accurate and impactful bass response. The woofer is magnetically shielded to reduce interference from other electronic devices, resulting in clean, distortion-free sound. Furthermore, the woofer is placed in a shallow waveguide to improve performance and reduce diffraction, resulting in a more coherent and natural sound. The woofer in the Revel-Concreta B-1 offers exceptional performance and is capable of reproducing even the most complex and demanding audio material thanks to its advanced design and engineering.

Cotton/Nomex blend
The Revel Concreta B1 speaker uses a Nomex/cotton blend for its midrange and woofer drivers. Nomex is a synthetic material with excellent thermal and mechanical properties that is used in a variety of applications. When combined with cotton, it yields a strong and durable material suitable for speaker drivers. The Concreta B1's Nomex/cotton blend contributes to accurate and detailed sound with low distortion. Furthermore, this material is resistant to high temperatures and humidity, making it an excellent choice for speakers that will be used in a variety of environments.


Functions for metric room EQ
The advanced parametric room EQ functions on the Concreta B1 Revel allow users to precisely adjust the sound to suit their specific listening environment. This is accomplished by utilising an integrated DSP capable of analysing and correcting for room anomalies as well as optimising the performance of the speaker drivers. The end result is a highly personalised listening experience that is tailored to the user's specific environment. The parametric EQ functions can be accessed and adjusted via a mobile app, making it simple and convenient to optimise the Revel Concreta B1's sound.

The Revel B1 Concreta  features a sturdy cabinet made of MDF and lacquered in either black or white. It has a distinct minimalist design that will complement any modern home décor. The cabinet is also well-damped, which helps to reduce resonance and improve overall sound quality. Furthermore, the speaker comes with a magnetic, removable grille that protects the drivers while also giving it a sleek, streamlined appearance.


Frequencies of Crossover
The B1 Revel Concreta has a sophisticated two-way crossover network that uses high-order Linkwitz-Riley filters to ensure precise driver integration. To maintain optimal dispersion and frequency response, the crossover frequencies for the tweeter and woofer are set at 2.5 kHz and 300 Hz, respectively. This enables a smooth transition between drivers, resulting in accurate and detailed sound reproduction. The Revel Concreta B1 delivers a natural and cohesive sonic performance that is true to the source material thanks to careful crossover design.

Finally, the Revel Concreta B1 is a small and versatile loudspeaker with high-performance sound quality and a stylish and modern design. The pure beryllium dome tweeter and the Nomex/cotton blend woofer provide accurate and detailed sound reproduction. The parametric room EQ functions, as well as the adjustable low-frequency response, enable customised sound tuning to match any room or personal preference. Durability and longevity are ensured by the high-quality construction, which includes a rigid aluminium cabinet and copper internal wiring.
