Do It Yourself Speakers

This site in general is good for theory and background and if you go to the index then to section 16 they have a lot of recommended kits.

There are quite a few very good diy kits out there but there are a lot more that are not so good. I can recommend Northcreek kits based on experience. it has been a few years but they are very good

Hello,
There is a website dedicated to a rendition of the Proac Response 2.5 speakers, great speaker, and a lot of the homework is done! Go to : geocities.com/diyproac25/

If you have the itch,scratch it but build an assemble-it-yourself kit first before you try building a pair unless you have ability in physics,acoustics,cabinetry,and more.

Just spent months studying and let me assure you that Elizabeth hit the nail on the head. This is no easy chore if you want to have something that sounds good. It could easily cost you more than buying some premade speakers. It's way complicated. I started out wanting to build a world beater. I am going to start with a two way and see how it goes. These will be surrounds so and will cost out of pocket around 600, at least that is what I am guessing, crossovers can get expensive if things don't work out and the theoretical is usually wrong so more expensive parts must be bought. Check out the Parts Express site for diy: http://www.pesupport.com/cgi-bin/config.pl?index
Lots of good info. Ask questions and read before you spend your money. Kits are a good way to go too. I didn't realize how complex they are even though I had a much better idea than most people.Cheers
