The magestic 4th order

[murph 10+ year member]

I know that the bigger the ratio the better but, when does this draw the line. Also on the sealed half what is recommended to go with the factory recommendation or what? Any other info that you may want to enlighten is appreciated.

There are many box builders on here with knowledge.

completely agree with this lol.

also, if you want a quick answer you can run a simulation on winisd to get an idea, but for a detailed response wait for moble enclosures.

last I heard he was pretty busy with box designs so might take a couple days but worth the wait //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I am looking for different facts no specific to an enclosure I am designing but, in general. Again there are many box builders on here with much knowledge.

sealed half is sometimes to spec. other times it could be cut in half. all depends. i draw the line at 5:1 for daily.

What effect does no going to spec have on the performance? When looking for the best low end response I would assume cutting it in half would not be good.

power handling also plays into the sealed side. there's a pretty good thread on caco about 4th orders.

I'm just finishing my first one ever, for 10 18's. Pretty happy with it so far....

I was told the sealed side should be smaller if you plan on big power but for low to moderate power you can go bigger I have built a couple in the past and they either sounded way to peaky or they sounded good but would eat woofers lol.

depends on what ur requirements are for. the general rule of thumb is 3:1 but i have seen 1.5 :1 work pretty well but i havent gone over 3:1 before

Sorry, I totally agree haha.

 

[murph 10+ year member]

Yeah I know the ideal ratio is 3:1 and I plan to get as close to that as possible.

My suggestion would be to keep the sealed chamber at spec of sub or just below it unless you enjoy buying subs.....i found this out the hard way......lol

Ok so in a trunk would there be any benefit facing towards the trunk vs. aiming it in the cabin. (not sealed off) Does port size play a large factor in the performance the box?
