Most large box subs require less power to run loudly, but the sound quality you get from them isn’t great. A small box sub requires more power to run. They will sound better than a large box sub with less power, but won’t be overly loud.
If you are willing to invest the extra money, your best sound quality will come from a large box sub that is equipped with a lot of power. This sub will play both loudly and accurately.
Once you find the right sub for your system, you then need to find the right place to put it. A subwoofer will perform at its best when placed in a corner, giving you more bass.
To ensure optimum performance, in any room, Paradigm has developed a system called PBK, or “Perfect Bass Kit”. This new technology actually changes the curve of a subwoofer based on where it is located in a room.
PBK comes with a software program. It works by connecting the Paradigm subwoofer and a microphone to a laptop using USB cords, while running the Paradigm PBK software. The software plays the sub, while the mic reads the room and measures out a bass curve. The software will then modify the subwoofer, giving it a smoother curve, based on the parameters of the room.
Generally speaking, if you want your bass to be loud, choose a large box sub. If you’re looking for accuracy, choose a small box sub. If you want loud and accurate bass, invest in a large box subwoofer with high power output.
