ok guys im new here. and actually kind of new to building boxes (well building them correctly anyways). i mean ive built boxes before when i was younger, but never tookin into consideration building the box for the sub or subs. i need somebodys help on box dimension. this is goin to be my daily and i probably wont be competeing with it but i do want it loud as possible. i have a 12" hifonics goliath 2400 watt sub, and i have no idea what to build the box to. pics of my amps and the sub are in my gallery or in my introduction thread. can anyone help me?

thanks in advance
ben

This is what I use it's really easy figure out your max dimensions and put em in. Find out what frequency you want and how many cubes you want and go from there you can get the info on what the sub is best for by searching or just call hifonics and see what they recommend http://reaudio.com/speaker_box/LPort_Box_Calc.html. For daily most ppl say (dont quote me on this)32 or so.

I like 32-36. Haven't tried any lower but any higher and it's a bit too 'peaky' for me.

ok so my next question is how big should i make the box? i can make a box up to a lil over 4 cu ft should i make it that big if i can? infact i could probably make it a lil bigger.

Well what do your subs call for(you can search or call hifonics), build the box to what the subs need. Usually you figure out what volume you have in your car and then pick out your woofer set up. If you don't give the subs proper air space they will not work to the full potential. And I'd tune it from 30-34 or so for daily. Thats what I do. And be patient with the bumps you will get responses in time. Good luck. But I'd say maybe 3-4 cubes just off top of my head. Also make sure your port area is correct go for 16" for every cube. What are your max dimensions?

well im not exactly sure what the sub calls for. i have some box specs from a manual i found on line, but its for a competition box for spl @ 80 Hz. i can build a pretty big box for my sub to put in the hatch in my car. its just gonna be a big flat box. i figured out a box on the re calculator and acording to it i can build a box thats 4.234 cubes @33.385 Hz

like i said either search for the specs or call hifonics the last thing you want to do is just put it in a random size box. and make sure you have the right amount of port inches for 4 cubes it should be right at 64

ok well what specs am i looking for? like i said i have the manual that i found online. it has specs in it. so what specs do i need and where do i plug them into. i know i dont want to just drop the sub into a random size box. thats why i posted this thread. and also like i said i used that link that you sent me to kind of get an idea of a box design.

you need to know what size box (how many cubes) they recommend for the sub, if you call they will tell you right away

well the one they suggest in the manual is a Vb of 2.5 cubes and a V(total) of 3.231 cube. BUT its for an spl box to be burped at 80Hz like i said in one of my previous posts.

on a side not is there anyone out ther that has any experience with the Hifonics Goliath subs?

ninja edit: sorry on1 im retarded and didnt read your entire post, and im actually on the fone right now with some one from hifonics right now. really hope i didnt come across as a di*K. just tryin to learn
