Those Cornwall IV's are a very nice speaker. And you are talking to a guy who has both Spatial X5's, and Cornwall IV's. I haven't owned a box speaker for almost 30 years until Don Sachs mentioned the Cornwalls last fall and he told me about some mods that really brought them to another level. Not that they aren't a very nice speaker right out of the box, but a little dampening on the horn and enclosure, and minor work on the crossover and they really sing. To this day I have trouble choosing which set I like better. The bass is different between the two, with open baffle a bit more natural on some recordings which some people may not be used to. Also the X5's can be more 3D soundstage and immersive at times, but it may be because of the room they are in. Both those speakers are a great value and perform way above their cost level. You may want to look into the mods for the Cornwalls as total it comes to a bit of time and a few hundred bucks for parts. Then again, the Spatials OB design concept is fun to listen to also although I think you will miss the upper register horn in the Klipsch if you go to the M series. If you are wanting to try Spatials I would go to the X series with the Beyma AMT or you may feel you've lost something in the upper registers. The X5's to me are very immersive.
Tough call.
