    Jim Wilson, Home Theater Shack Moderator/Reviewer, took a look at the S1800 home theater subwoofer. Click on the Home Theater Shack logo to read the full review."

    "Whether it was the sound generated by thousands of hooves or the guttural snarls from the Morgul beasts, the S1800 resolved them all with exquisite detail. No part of the soundtrack washed away, regardless of how complex it was."

    "The simple and thick rhythm of this song lends itself to something that would play well live, so it was that volume level I decided to try and replicate. While no single 18" subwoofers could effectively achieve that much impact in my living room, I still pushed the S1800 toward it nonetheless. In the end it did a remarkable job; Carmine's bass was abundant and silky smooth, which contributed mightily to the slick beat. This became one of those "have to listen again" tracks, so I did just that. "
