LZTYBRN Posted April 7, 2011 Author Report Share Posted April 7, 2011 Any idea on how long this deal might be around? I wasn't planning on buying these subs soon, but I will if the deal is for a limited time. Quote Link to comment Share on other sites More sharing options...
LZTYBRN Posted April 7, 2011 Author Report Share Posted April 7, 2011 Okay back on topic. Say I wanted four P1S415's on about 600W RMS total, what volume and port area might you recommend? Quote Link to comment Share on other sites More sharing options...
LZTYBRN Posted April 7, 2011 Author Report Share Posted April 7, 2011 Well, using the recommended box volume of 2.00-2.80 cubic feet, I assume I would take the larger number since they will be underpowered. Then multiply by 4 to get the total net volume for all four woofers. Then I would get 11.2 cubic feet. Then using 12-16 square inches per cubic foot rule of thumb, I would need 134-179 square inches of port (that seems pretty big.) What do you guys think, sound like good volume? How bout port area? Will that work well for these subs? Sorry 4th post in a row, but I'm bored, and I want to figure this out. Quote Link to comment Share on other sites More sharing options...
RooTxBeeR Posted April 7, 2011 Report Share Posted April 7, 2011 Use Torres calc, will work nicely aslong as you put in the right numbers.

LZTYBRN Posted April 7, 2011 Author Report Share Posted April 7, 2011 Wouldn't that only be useful if I already know the volume and port area I want? Quote Link to comment Share on other sites More sharing options...
Torres Posted April 7, 2011 Report Share Posted April 7, 2011 not necessarily. unless you have a huge caravan where your dimensions are pretty much boundless, you have a set space to work with. so it looks like you have the volume you are aiming for, and a port area range, now you gotta figure the workable dimensions you have to work with. you enter those dimensions in the calculator, enter port dimensions and adjust port length to get a tuning to your liking. you may see that you have ample net volume or you may see that you don't have enough volume with your current dimensions. so you tweak the box/port dimensions till you get what you want. see what i'm getting at?

LZTYBRN Posted April 7, 2011 Author Report Share Posted April 7, 2011 Okay that makes sense, but how will I know if I have ample net volume or not? Quote Link to comment Share on other sites More sharing options...
