You know, for many of us there is no better feeling, than to have built it yourself. The sense of pride, that comes from building it yourself.
We think you know what we mean. The first one may not be perfect, but you had fun building it, and most of all, you learned more than you thought.
This is a pretty straight forward project. You get a 8" Dual Voice Coil Sub Woofer, Sub Woofer Crossover, and Port. Three little components, that will bring a some bottom end to your system.
You can always think outside the box, and put your own design touch to this project. The only thing you need to keep in mind is that the cabinet needs to be kept to about 1 cf.
The kit consists of:
- One Acoustic Research 8" Dual 4 ohm Voice Coil Sub-Woofer
- One Cerwin Vega Sub Woofer Cross Over
- One 2 7/8" Tuned Port

Our 1 cf. Basic Cube Cabinet Design:

Works with a cabinet volume of about 1 cubic foot.
If you built cabinets with inside dimensions of 12 inches by 12 inches by 12 inches, & if you use 3/4 inch MDF your outside dimensions would be 13.5 inches by 13.5 inches by 13.5 inches, but build to suit you needs, just keep the internal volume to about the 1 cf model and you'll do fine.
*Note that a good material for this project is MDF, you can buy a nice piece of MDF shelving at your local building supply house for about $5.00 in 8 foot lengths (one 8 foot length should be plenty for this box), some have a nice rounded nose for a stylish look. For about $35.00, you can build one heck of a nice sounding, and performing subwoofer.
*Building and design note, the output from a sub-woofer is non directional. Built to suit your needs, you can think outside the box, because placement isn't critical. Place under a table, behind a seat, in a corner, the woofer facing to the bottom, front, or side firing it doesn't matter, just place close to a wall which will act as a resonator and improves performance.
**Remember, the only thing that you hear out of this box, are the very low frequency's. This can take some power to reproduce, work with at least 20 to 30 watts. Listening to it by itself, is not too impressive, the joy will come from the full chorus of speakers.
