Want to build a box.

[Rebel4055]

Alright I got a pre-built box right now but I have NO idea what it is tuned to, I want to build my own box for 2 12"s see my sig for my subs.

I want it to hit lows REALLY well and highs too, I was thinking about 32Hz?

Now I've never built a box before I don't want a HUGE box cause right now It's being used for my room.

If someone can give me some measurements I could see if it would work in my room.

EDIT: If I can't build it I can see if my local audio dealer can.

Yup! And check my sig . I was thinking of a L port.

If it is purely for the house (to be specific, movies), tune low, like as close to 20hz as you can, maybe lower. You don't have to but it can give you super low flat response (very important for movies). Only problem is that that will make the box huge (unless you get funky with the ports).

hmm. 30hz tune then. Should be good for most music.

EDIT: depends on sub and box though. I can check it on bassbox pro.

If you could that would be great Sub's are listed in my sig.

Why is 20hz ideal for movies? So is all home theater subs tuned to around 20hz?

Cool, I'll check it out in a hour or so. Busy ATM.

Why is 20hz ideal for movies? So is all home theater subs tuned to around 20hz?

All movies have bass, as you know. Every movie will have it down to 30hz (a few won't but most do, even if it is just a door slamming or music of some kind. Action, sci-fi etc. will almost always have it down to 20hz (as before, not always, but a lot do) This is your explosions, strange futuristic equipment, etc. And some even have it down to single digit frequencies, the LOTR trilogy (Lord of the rings) has content down to almost 5hz in some scenes (I think the catapult scene in the second one, I think it's that one) and other movies can reach 10hz.

Now of course it is impractical to create 10hz at 120db in your living room if you only watch movies occasionally (and don't have a $8,000 projector and $3,000 speakers) but like we here strive for loud bass, so do some home theater people. Aiming for as loud and low as they can by mounting 8 18" in a infinite baffle (and they sure do get 120db at 15hz, maybe lower)But cheapish commercial home theater subs, while able to maybe reach 20hz, only get there at -10db or similar (unless it cost lots of monies!) as they are tuned higher. They are tuned higher because the average person doesn't want a hulking 6 cubic foot monster in the corner of the room when it only has a 12" or 15" in it.

In short. 20hz tuning is great because it (mostly) allows the sub to play louder at 20hz frequencies without bottoming out, and lot's of movies need that capability.

And,

no, only some are.

So you are saying the hi end home theaters subs are tuned to 20hz or lower and your telling me you heard a 5hz tone?
