Review on 🎵 Monoprice Alpha Series 10 Inch In-Wall Subwoofer - 300 Watt, Easy Install for Home Theater - Carbon Fiber by Cristofer Cejudo

I used 4 of these as surround speakers in my home theater project and couldn't be happier! Reliable drivers, powerful crossovers, a solid and simple mounting system, excellent magnetic grilles, and a high-frequency attenuation selector that remains accessible after installation. This is a very good design for inexpensive speakers. My Denon AVR rated these four speakers as nearly identical and easy to balance to 40Hz. I set the AVR crossover to 60Hz as this is surround sound and I have plenty of bass available from the subwoofers. They were all tested for nearly identical frequency response. Unsurprisingly, this isn't always the case in this price range. They also have very strong, spring-loaded, gold-plated connectors that can work with any wire or connector you choose to use. They proved to be a great complement to the MP. I used the Alpha ceiling speakers for the Atmos overhead speakers. Highly recommended!
