@berber99 - Yes, they are sold as a kit, and need subs to be full range. They were not difficult to build, but took about 50 hours including building the stereo open baffle subs. See my post

I didn't have a chance to listen to them first, but I was convinced after watching many of Danny Ritchie's (the designer) Tech Talks (https://www.audiocircle.com/index.php?topic=165408.0) that he knew what he was doing, and had a similar perspective on what was important as I did. If you are interested, contact Danny at GR Research and he can put you in touch with someone near you (of exists) that would be willing to demo them. I'm in Portland, OR.
@uberwaltz - The NX-Oticas are a bit out of your price range, particularly if you add the subs which I think are necessary for most music. But GR Research has other options that would fit your budget if you are interested. Many are not yet listed on their website, so give Danny a call.
