[QUOTE="JimGore, post: 73050, member: 3"] When designing a sub you can approach it from three angles: 1. Get the best sound quality and detail. Sound quality route. 2. Get the loudest and biggest. SPL route 3. Middle route - bit of both. For SQ (option 1), you will generally go for a driver with a low Qts (0.2 to 0.4) in a smallish sealed enclosure. You will aim for a total sytem Q of as close to 0.5 as you can get as this gives a very neutral and detailed but tight bass that integrates well with the mains. For fire breathing, kick you in the chest, rattle the door frames insanity (option 2), you go for a driver with a Qts of between 0.5 and 0.8, with a much bigger bass reflex enclosure, tuned for maximum output while keeping the driver safe within it's excursion limits. With the bigger box, the bass becomes less tight and controlled, and you get more of a feeling of power when listening to it. For the middle way (option 3), I usually go for a smaller bass reflex cabinet such that you still get good extention, but other things such as group delay and transient response is improved.
