Hi,
I believe drivers, parts, and boxes should be viewed as a sum rather than parts. Example, a ribbon tweeters may be great, but its xover point my be high and requires a mid range that can reach higher frequencies. Conversely, some of the Scanspeak tweeters are awesome and may allow for a lower xover point, allowing you to pick a different mid. A great diy speaker site is linked below. All the parts interact together, so it is the best integrated system is what you are looking for. Enjoy.
