Help with box for dc lvl 5 with psi soft parts 18" sub

[solar0987]

Got some parameters for the sub. Need 5.5-6 cubes with 17sq/in per cubic foot. of port. When i input that into torres its auto tuned to 34-35hz. Think that would be better than 30 tuned with less sq/in per cubic foot. of port space? Less being 14.34 sq/in port

should do fine. 5.5 is a-little on the small side but it should be fine. 30hz is lower than i typically tune but they is acceptable as well

Talked with sean over at dc. He said my specs were pretty dead on. but to make the port a little bigger and tune for 33hz. So thats what im going with. 5.7 cubes braced will be around 5.5 from his and my calculations. He is a really nice guy! Box will be built sunday sub should be shipped by now, wires and terminals are otw, volt gauge is otw, now just another battery and a amp.. decisions decisions..

I dont think you understand what T/S parameters are.

Because its nothing DC can tell you over the phone, nor PSI for that matter.

As I get you, this has a total cost of 68$ The specs from psi and dc are pretty much the same. Talked to the guy i bought it from also. Everyone is agreeing that this will sound good, what am i missing?

The fact that the woofer in question has to be ran on something like a Dayton Audio WT3 or a SMD IM-SG to have the T/S parameters pulled from the woofer to know things such as fs, mms, le, re, rms, bl.

Things that no one knows especially on a woofer that has various parts used that differ from the oem parts.

5.5 to 6 cubic feet with 17 square inches of port per cubed tuned at 34-35hz are not T/S parameters.

Those numbers just mean its a rather generic enclosure size.

Like a prefab enclosure....

Some numbers that make up an enclosure that you could put a few different 18s in to and it would work, but will it be the best. Nah.

Well with talking to dc and psi, they said 5.5 cubes at 30hz is a great start anything bigger and it doesnt sound as good. they said 30hz would be fine also. there are otehr calculators on the web ill try a diff one then. I just need cut sheet for box really so I can build it. I have tried asking for help here and no one answered. I just want a basic boz ported to 30hz at 5.5 cubes top facing sub top facing port. dimensions can be 36x21x21 at most. And them parameters are not on there site. Know where i could find them?

Since what you have is kind of a FrankenSub, you aren't going to find the T/S parameters anyway, they would have to be measured from the sub.

I think your idea of just putting it in a 5.5 cube box tuned to 30 Hz is reasonable. Have you tried using something like Torres to come up with a box plan?

Do you have a good link for Torres and WinsID?
