I cant find the displacement for my sub. I was using WinISD and following this video on how to use it How to Design a Subwoofer Box - Design Software and the Math! Car Audio Fabrication CAF - YouTube (http://www.youtube.com/watch?v=qJl3SDfuI9Y) , but once it got to displacement I couldnt find it. Here is the manual for the sub http://www.hifonics.com/current_manuals/hifonics_brutus_brz_subwoofer_manual.pdf I have the BRZ15D4

I also tried making a design with RE AUDIO - Box Calculator (http://reaudio.com/box.php) but got confused because the manual has 2 ports instead of one, so i didnt know what to do since the site only allows for one.

Also if I cant do this, how much would it cost for someone to design, build, and ship one of these?

Whenever this comes up I try to find a driver with a similar size basket/motor that I can find the displacement for and use that figure. Being a 15 inch driver you could probably just use .15 cu ft as the displacement and it will get you close enough. It wont be so far off that it would affect anything all that much.

A simple design from me runs $25 a box would run $135 plus shipping and theres a few questions I would need answered like what amp you using what vehicle whats your musical taste and will you be competing or just a daily setup.

.15 cube is a safe enough guess. Difference should be inaudible in this application.

Well the sub i have right now im hoping is just temporary, so im not looking to get too crazy or the PERFECT box just yet, I tried making a design with RE + WinISD but i dont think either factor in that the sub im running (the manual at least (manual is here http://www.hifonics.com/current_manuals/hifonics_brutus_brz_subwoofer_manual.pdf )) says I should have 2 ports and not one and im not real sure how to factor that in to the calculator. How much do supplies cost? Dont know what else I would really need besides wood, my dad does a lot carpentry and said he would do the build and im sure he has a lot of the stuff you'd need already.


BTW I understand you want paid for a design which i completely understand and will most likely do once I get my new subs but im on a tight tight budget now after buying all this stuff

Well the 2 ports thing is not needed its just a rough idea as many manufacturers do cause they dont know how much power you will run what vehicle you have or your musical taste re calculator is not accurate unless they fixed it.

easiest thing to do would be to email maxxsonics and ask them.

Easiest thing would be hit up dad with the box volume, shape and where it's going to fit.

3/4 mdf sheets (4x8) run about 35$ each. Toss in some wood glue and screws... paint / carpet?
