Especailly since you can make your own box for 1/4 of the price! :)
Thanks for the idea..
Well if you want to simply 'throw a box together', and don't car about how it looks, or the quality/loudness of sound, then yes, you could make one for under $100. A sheet of chip board should do it.
You probably already know this, but I'll say it anyhow. On the average installation, there is about 6dB which can be gained simply by altering the enclosure, give or take a few dB.
This may not sound like a large difference, however I assure you it is.
For example, you have a 12" sub in a n enclosure, with lets say, 200WRMS. If you go out and buy another identical sub & amp, and put it in the car, in another enclosure which is the same as the first, then the maximum possible dB gain will be 3dB over your original dB reading. (Thatís with 2x12's with 200WRMS to each)
In order to gain an additional 3dB, you will then have to double your current setup. This means having 4x12's and 200WRMS to each.
Am I making sense?
So, by playing with different enclosures, you are able to tune the enclosure to you woofer properties, as well as your car. There are many gains to be had.
SPHELL for example gained around 2dB in his setup by making some small adjustments to how the box was installed in the car, this probably didn't even cost him anything.
I spent 8 months playing with trial enclosures for my car, and the final result produced far greater performance then my initial installation. It saved me a hell of a lot of money in audio equipment.
If you go the ww.caraudioaustralia.com website you can check out there current SPL project. This also demonstrated the importance of enclosures.
It all depends on what you want out of your audio system.
Iíll shut up now.
