Holy Crap!

Yeah, i think that is a little out of my price range. I dont think it would be good for my basement too! especially if i take it with me when i leave! hahaha

Hey Slappy, as previously posted, I had owned a Audio control Richter Scale and found it to work well for me. It is budget priced.

good luck, Paul

Before you even think about spending your first penny, buy and read a book called Loudspeaker Design Cookbook by Vance Dickason. While it is not hard to build a subwoofer that shakes, rattles and rolls, it is tough to build one that is accurate, articulate and built as well as it should be. You might find that the driver(s) that you want to use are not suitable for the size and type of box that you want to use. If such is the case, think about how much time, money and frustration reading this one book might save you. Sean

Slappy, first off, GOOD LUCK!

You shouldn't have as much trouble as a lot of people will try and tell you.

Second, I am not so hot on using a car subwoofer for a driver, Infinity or otherwise. These drivers are normally 4 ohms, which may or may not be what you are looking for. They tend to appeal to a different sensibility, and often focus their performance in the 60 - 200 Hz band(mid and upper bass), which is at odds with the audiophile goal of producing low bass, under 60 Hz.

These drivers will make you happy if you are looking for what most people consider "good bass". Booming, shaking, mid and upper bass. As my friend Michael here likes to say, they rattle the guy three cars back. The box alignments they drivers are placed in, and are optimized for, play right into all of this.

Honestly, if you are looking for a pair of stereo subs which will produce clean, articulate bass, you can definitely do this project. You only need to do a little homework. Drivers from Madisound, Zalytron, Peerless, and Vifa are great for a vented box, and will fit well into your budget. Audio Concepts specializes in sealed box drivers, and are also a good move.

I would suggest that you find out whether your preference lies with the sonics of sealed or vented boxes, as there is a personal preference in most of us.

Other than that, look for a decent pair of plate amplifiers.

Since you are doing the cabinet work, it will cost not a whole lot beyond your own time and patience. 4' X 8' sheets of MDF and glue are certainly cheap enough.
