Hear Every Detail

Designed for high-caliber audio systems, Revel's compact Performa4 M145 bookshelf speakers are engineered to extract nuances from music that would otherwise be lost. The M145 houses the same woofer and tweeter technology as the rest of the Performa4 series, boasting a 5.25-inch Micro Ceramic Composite (MCC) cone woofer, a 1-inch Deep Ceramic Composite (DCC) dome tweeter, and a 7th-generation Acoustic Lens waveguide. You’ll be amazed by this speaker’s generous 54Hz–40kHz frequency response, ensuring unparalleled detail and a cohesive soundstage. Moreover, it includes a high-order crossover that offers seamless driver integration across the board and a newly patented cast frame engineered for improved airflow and cooling. You also get a magnetically attached grille, providing you with secure, rattle-free protection for the M145’s drivers while maintaining a sleek visual aesthetic. With a set of M145 speakers in your home audio setup, you’ll transform everyday listening into a truly world-class experience.

Revel: remarkable realism backed by rigorous testing

Guided by a passionate philosophy of delivering highly accurate, true-to-performance audio, Revel immerses listeners in pristine, realistic, high-fidelity sound, all while preserving the artist’s original intent across the full frequency spectrum. Founded in 1995 under the Harmon International umbrella, the company is renowned for its engineering-driven process, melding high-precision craftsmanship with industry-leading acoustic research based on vigorous double-blind listening tests. At Sweetwater, we’re duly impressed by Revel’s state-of-the-art proprietary technologies, such as Acoustic Lens waveguides and high‑linearity excursion transducers, which give rise to listening sessions with natural bass depth, clear highs, and lifelike vocals. Over the past 30 years, Revel has built a legacy of innovation across its acclaimed series — from Ultima and Performa to Concerta, Architectural, and Extreme Climate — culminating in award‑winning designs, including the PerformaBe line and flagship F328Be, while maintaining an ongoing commitment to creating some of the most accurate loudspeakers available.
