i wasn't saying it was wrong just seeing if there was other contributing factors. do you have a build log???? and sorry for the thread jack man

[DudeWith4x4]

Well I really need to figure out what I need for measure ments. I sent sanitarium a message but no response..

what measurements did you need? sorry i didnt read the whole thing

[Jd1102]

i heard 1.5-1.75 is good for most 15's

i heard 1.5-1.75 is good for most 15's

depends

im using xls and they're about 1.79 per.

but i have the level 3's

if i were you id start on the lower end closer to 1.5 and then if you dont like it add some polyfill and make the sealed side larger.

[DudeWith4x4]

I forgot about polyfill.. I would like to use a smaller amount if it won't affect the quality to much.

personally for a 15. id stay close to 1.5 1.6 range.

but i like to ground pound. and have lots of port. so that should dictate your decision. most of the lows response are dictated from the sealed side and ratio.

[DudeWith4x4]

So 1.5 sealed.. 3.0 ported? So like 45hz?

[D-train-13k]

So 1.5 sealed.. 3.0 ported? So like 45hz?

yup.

that should be nice. make sure on your port design that you dont choke up the ports like this

it was tuned about 45. but it was super peaky and would not play the lowes.

I'd stay around 1.5 sealed with the level 3 15s. Assuming your not going for spl...
