PPI 104 subwoofer enclosure help

Yeah i think so its going in a 4 door civic trunk not sure if you can put a 4th order in a trunk and sound good never seen one in anything but a suv

if the back seats fold down should be fine. or if not ported through back dash

[vike4511]

I told him I could port it through the rear dash not sure if the seats fold down or not I'll ask him tomorrow

Yes it says 0.9cuft@32Hz for a ported box, a 4th order improperly designed or built can be a disaster.

If you need lows just skip the sealed, the manual states exactly how to build the ported.

Ok I think I'll stick with a ported till a get some practice at a 4th order

yeah it could be a disaster but youll never learn without trying. i guess you could always just rely on someone else for designs

I modelled this driver out of curiosity and found that it works great at 2cuft@32Hz at rated power of 300W. It's a gigantic enclosure for a 10" but it works giving bass down to 30Hz. You may want to try that.

Sounds good I'll talk to him tomorrow at work and I'll let him know those specs and I'll move on from there. If I have any questions can I pm you?

[Joe X]

If you have any questions just post them here, I also checked the 0.9cuft suggestion and it looks really bad, I almost guess that sealed would be better for them than their ported suggestion, those subs have very low EBP.. if you are curious I could post some frequency response plots for you to see.

I think I'm just gonna tell him sealed or a ported enclosure. I'll play with 4th order with my own equipment for practice once I decide to build. I'll stick to the 2cuft @32hz see how that works otherwise I'll build him a sealed. Thanks for the help
