As part of our new powered subwoofer measurement protocol, we will be offering a room size recommendation for each subwoofer tested based on the data gathered from our exhaustive CEA SPL vs frequency and distortion output testing. It is our hope that the methodology we chose in determining the room size capability for subwoofers can be a useful general rule of thumb for an end user attempting to determine which model is right for their listening space. We always recommend multiple subwoofers for more overall output and smoother bass response from seat to seat. The goal for a great A\/V system is lots of clean output and a similarly good listening experience for all listening seats in the room, NOT just the money seat. See if your favorite subwoofer will get our "Bassaholic" recommendation.\n\n\nDiscuss "Audioholics Subwoofer Room Size Rating Protocol" here. Read the article.
