David Susilo provided an in-depth review of Monitor Audio's Anthra W12, the midrange model of the trio of subwoofers, praising its high value and powerful performance. He also made a brief video review which you can watch via the link at the bottom of this page.
"The subwoofer didn’t lose a single moment and reproduced the terrifying rumble of the tanks with great authority. The shaking felt real as if a tank was right outside my theatre. Tank fire had the necessary weight while ordnance explosions and weapons fire had a very naturalistic tone to them."
"Scene after scene, movie after movie, song after song, this subwoofer never disappoints. It’s powerful, has a big sound, and is dynamic all at the same time, which makes this sub a perfect companion even for something as mission-critical as a mastering studio."
"All in all, I have nothing negative to say about the W12... The adage you get what you pay for is not valid where the W12 stands. With the W12, you get a lot more than what you paid for."
