Moving into my 3rd speaker build currently. I am trying to build a high end bookshelf. Performance should match speakers in the $1,000 to $2,000 price range. The design goal for this build is crystal clear midrange (within reason for a 2 way), and low distortion in the low end. This build will be paired with a sub, but I want the speaker to be able to perform reasonably without one. To achieve my design goals I have chosen to use a larger speaker driver, 7-8in rather than a 6in to achieve a better base response. I narrowed the choices down to two drivers. the Satori 7.5 in and the Revelator 8531g 7 in. The satori driver I know has a wonderful and rich bass, as demonstrated in some of Troels designs. The revelator woofers have a good reputation, and have also been used in many notable designs. I have not been able to find any distortion or FR measurements for these drivers (I actually found some for the revelator but none for the satori). I was wondering if anyone has either used these in 2 way designs, or has measurement for them. (It is worth noting that I also considered the SB ceramic cone drivers for this build, but some measurements from Erin's Audio Corner showed serious distortion in the bass. Its strength being the midrange was incredibly clear.)
As far as tweeter choice I am spilt between the Seas DXT, and the Satori TW29RN-B-8. I have heard that the DXT is an unbelievable tweeter, but have also been told that it is very difficult to work with integration wise. The Satori tweeter again is used in one of my favorite Troels designs. Obviously I will finalize my tweeter choice once I know what woofer I am using, but I though it worth mentioning.
Bottom line,
In the future what are the things I should be looking for in a driver when I am trying to evaluate its validity for a certain design. Suggestions on this build in particular would be greatly appreciated, but I would like to avoid writing a whole thread for each speaker build I undertake 😆.

Partially, it’s good for look at bass response, but the measurements don’t include a distortion or waterfall graph
High end loudspeaker is more about skill than driver price range. You seem not to take that into consideration.
Secondly, the commercial loudspeaker price range you are trying to match your to be speakers involves
parts far below the quality of the chosen drivers and both of these have large Vas values suggesting
building a larger enclosure to fully deploy its bass potential. By choosing a bookshelf type cabinet
you will be driven in the sealed cabinet territory, restricting bass performance significantly, depending
on your personal expectation.

‘Difficulties’ with integrating the DXT possibly stem from the fact that users aim for a higher target (directivity wise) than the average TW29 user does, quite a few probably never heard of directivity control. But all the same it isn’t that hard to integrate, if you know what you’re doing.

If you are interested in the DXT, and how to make it behave, this link might give you a little insight if you look around.
