  • Rated 5 out of 5 stars

    Solid choice

    These are surprisingly enjoyable to listen to coming from someone that's a budget audiophile and worked in professional settings as well. They're currently mains in a moderate size loft with vaulted ceilings and handle the space fairly well. I do plan to add a second pair at the opposite end of the room and will fill out the bass with a sub. By no means a replacement for a full PA, but adequate for a yoga studio like space with the ability to not disturb adjacent tenants while still playing reasonably loud. The mounting bracket sets up with ease and is an easy system compared to many.

    Great speakers, if you have a seperate sub

    Speakers sound great with my sonos amp. Having a separate subwoofer is necessary in order to have the perfect balanced sound. Otherwise, is just a speaker.
