The SpeakerCraft Seamless subwoofer has a rectangular surface and has more bass creating surface area than a 381mm comparably sized round subwoofer. A rectangular subwoofer will sound louder than a traditional 381mm round subwoofer because the four corners give you greater moving air capability with more cone area. The extra surface generates a higher frequency response as well. For a speaker that is 100% invisible the amount of bass response is tight and accurate all the way down to 20Hz.
