DIY high end speakers?


Is there any consensus on which of the published (via Internet) speaker designs / kits are actually worth it? I am very handy (I design and build furniture as a hobby and have a full shop) and as a result am considering going the DIY route for speakers but I need a starting point for my research.

What are some good links and resources for me to check out and see if this is a good way to go?

Thx

It may also be worth noting that my current spekers are polk rt2000p mains and a polk cs400 center speaker...so that is my point of reference for now.
I've been researching this as well, and one of my favorite designs is the single, full-range, rear-loaded horns.

www.frugal-horn.com has many free designs, and forums of users that have built them. Good info.

Check out the Parts Express Tech Talk board. Lot's of DIY activity and tutoring on developing the speaker of your dreams if some of the off the shelf DIY designs aren't quite what you're looking for.
Tamule1, which speakers did you build by Troels? I have been looking at his designs for awhile now.

To the OP, you may want to check out GR Research which has a site on Audio Circle dot com.

Timlub, rather than hijack the OPs thread could you PM me as I would like your opinion on which type of speaker you think would work best in my very large but difficult room
Thanks gregfisk@aol.com
Kooshballa, you'll need 88db sensitivity minimum with an impedance of 6 to 8 ohms nominal. I would not suggest a 4 ohm speaker for your power. Next, with the music that you listen to, my instincts/experience says that you would most likely like a speaker that is not bass shy, maybe even would like a touch extra as long as it is tight, natural mids with smooth top end. Imaging is a response of phase & time alignment, so that can be handled, Let me know if I am on the right track and please include a budget for speakers and crossover components, assuming that you will be doing your own wood working.
If needed for your and Gregfisk, my email is timlub01@charter.net
