Hi peps, i have been given a Audiobahn sub (AW120T) and want to make a box for it.

It is a 12" 500RMS sub

I would prefer it to have a cu. ft volume of 1.6 or greater, it is a single vc sub. If there is anything else you need to know just ask. If there is anyone out there who can give me a bluprint of a box for this aplication let me know!! Muchly appreciated!

Cheers

what kind of car do you have? where do you intend to install it? Are you looking to get High SPL (Sound Pressure Level) or high SQ?(Sound Quality) The difference could mean either a sealed box or a vented ported box. What kind of amp are you pushing the sub with?

Download and use WinISDPro. It has that driver listed in its database with box size. You'll see that it takes a smaller box than 1.6 ft^3, and in fact, looks like it won't do well in a larger enclosure. That's not a SPL sub, and doesn't qualify as SQ either. It has an excursion Xmax of 10mm, so don't expect great volume. But you should be able to get good complimentary low bass out of it with a modest system. You should get best results ported in a slightly smaller enclosure, but run it through either that program or another and look at it yourself.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Hi, thanks for that. I am thinking about using a Pioneer GM-D510M Mono Amp to go with the amp. I am going to put it into a '00 Daewoo Lanos and would prefur the box to be vented to keep the temp down near the amps.

I have had a look at that site you gave me STEVDART and put in all the parametres and that means nothing to me sorry. Im hoping that there is some one out there who use that program to work out a the design of the box. I can give you all the specs that any program will ask for, its just i cant interperate that to mean anything.

Let me know if you need anything else, or if ya have something for me!

THANKZ HEAPS!!!

The site I gave you has a section of downloads over to the right. Pick WinISD Pro. It's free and relatively easy to use. Take your time and get to know it a little. That sub is already loaded in the database, as I said earlier, and all you have to do is click on it to get the recommended box and port size for whatever volume you want to use. I looked at it with that program to give you the info posted above.

I dont understand the line "would prefur the box to be vented to keep the temp down near the amps" What does this mean and do you understand what venting a box means? Im not being an ass I just dont know if you comprehend

double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Yea i know what its about, but a mate has a vented box, and has the vents facing in the direction of his amps, so with the expulsion of air out of the box it get pushed towards the amps. that is all i meant by that Sub Box? -- posted image.

ok Nat_87..........Im kinda new to the WinISDPro program myself so I kinda used your topic as a practice run. Anyway from what I gather if you build your box to these dimensions , It should get the best sound from that woofer. Inside dimensions should be 12.25" X 12.25" X 16" Your Port tube should be about 2.5" round and 8.25" in length. Your box will be tuned at 32.96Hz. Remember those are INSIDE dimensions and to concider wood thickness and such. Now this is only the 3rd or 4th time Ive used the program so if anyone would care to double check my work , please do ! ! Oh and the box dimensions can change as long as the internal volume equals 1.37' cubic feet. I know you Pro's are looking this over , go easy on me......lol

Ok, thanks for all your help. Next question, when i have the specs for the box and hav it all cut out, what/ if any stuff should i use to put inside the box. I have heard a few things, ranging from some sort of coating to cover the inside of the box, to putting foam or some sort of filling inside.? What does you the more experienced people think on this matter?

Cheers
