Do you want to know why tlines are so popular? Its not because of added efficiency, or wavelength phasing or any crap like that. It is because for this efficiency port idea to work the best, the compression chamber has to be also coupled to the driver, and the best way to make sure compression is there and not lost, we can make it non existent and rely on wavelength to couple without a compression, so we do not have to couple the driver specs much anymore.So, the best way to do it with a compression chamber, I.e. Ported boxes, is to use a small compression and a long and large port...as long as all of the frequency parameters work out, like electrical and acoustical coupling, phase response, output efficiency, driver control, etc. It is a work of art to get every one of those factors correct, and I can nearly guarantee that not many people knew that was why small compression chambers work well for output.Everyone thought because of high tuning....noooo...its because a smaller compression allows for less acoustical losses when adding a port that I s properly coupled to the environment. It just so happens that tuning is high because of the port characteristics. And efficiency is high because of crossectional area when tuning is high.You want a good spl box, go with a huge port and a small compression chamber. Watch what happens. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif</blockquote>
