SOon i will be getting a 12" Atlas. the site has a graph that says the sub will be most efficient tuned to 100hz (unless om reading it wrong). how would i tune a box to 100hz. if i buy just a custom box off the net, what do i have to do to it. or do i have to buy a certain specs box?

22 deep x 19.5 wide 13.5 high internal with one 8.75 high x 2.5 wide slot port the the depth of your box is the port depth....external measurements are 23.5 x 21 x 15 using 3/4 mdf board....your port will be tuned to 26 hz

ok but i thought sealed was quite a bit better for sq, thats what i was planning on. so can only ported boxes be tuned, or how do you tune a sealed box. since i will probably be going with sealed, what size box should i go with. the site either recommends .6 or 1.5 ft3, depending on what you want. i want sq thanks

so have you heard what works best for 12" Atlas, there are three suggestions on the site, i think ill go with 1.5 ft3 its the middle size. am i right about not being able to tune a sealed box? or if you can how do you do it?

sealed enclosures have a tune but you cant change it like you can with ported enclosures. They are tuned to whatever the lowest frequency the sub can hit which in the case of the Avalanche for instance would be 15htz. Remember the bigger the sealed bof the less power you need to reach full excursion.

ok that makes sense so just two more questions.
should i go with a ported box (tuned to the right hz) or a sealed one? im mostly going for sq.

www.ascendantaudio.com has specs for the best hz tunage (is that a word), but none for best sq. any idea what the specs are. also they have 3 suggested sealed box sizes, i think i am going to go with the medium one, is that ok or i bigger or smaller better. i know the bigger the louder, but does a certain size sound better??

Generally the larger the box the more effecient; you don't need to run as many watts.

Making a sealed box has it's pros and cons. A larger box offers a better low-end frequency extension, at the cost of some sound quality, because of a quicker roll off point.

Boomier is pretty vague and can be interpreted differently. Just thought I'd pretend to be Jonathan and explain stuff that you don't.
