Build my own speakers?

I have a couple of Madisound Odin speakers built from kits which are the surround channels of my system. They are IDENTICAL to speakers that I saw reviewed in Stereophile a while ago, at less than half the price, even with the premium crossover option.
Check out www.madisound.com

Here is another choice. These guys will facilitate a variety of DIY speaker design/build projects. I agree with the others here, you should let an experienced professional create the design, and match drivers to the crossovers. However, you could first decide what type of sound you are looking for, how much power you have, how big you want the speakers to be, and other factors, then find the right DIY project for you.

Do you want $20K speakers for the fraction of the price? Check these: http://www.northcreekmusic.com/#LoudspeakerKits

Thanks for all the replies. I am a serious audiophile. I have 2 degree's one in advanced mathematic functions (electronics) and the other in mechanical. The speakers i en-vie are Vandersteen 5a's. Richard did his homework as in I do. Richard also is coming out with a new speaker. I did my homework as well. I am going to design and manufacture the best speaker in the world for under $20,000. I just hope Richard will be my friend.

I am kidding. I am going to save up to purchase his speaker. Happy New Year everyone !!!!!!
