building monitors

[gary]

I'm looking for links, advice, and discussion on building monitors. I
recently replaced a woofer in an old cab and realized that the
components for making a speaker are much cheaper than the cost of
buying them. Is it a worthwhile undertaking for someone like me with
shop access and experience? Has anyone been successful in making great
sounding speakers? Are there kits for this kind of thing or tried and
true results following an instruction guide?

Thanks for any input
