[QUOTE="Wonderbread, post: 217620, member: 541455"] Brad, you are wrong... and here is why... In a sealed box, very low frequency output is minimal. the f3 (-3 db down point) is usually fairly high (above 30 hz in most cases). the only way to lower this f3 spec is by DECREASING the Qtc. of the enclosure - making it vastly larger than Butterworth configuration. Sealed boxes are also, by nature, less efficient. Vented (bass reflex) boxes can have their f3 point near or even below 20hz. Basically, they get louder, lower. plus, they are more efficient, about 3db more efficient. [/QUOTE]
