The HD-1s cover a wide range and, if you're into rock music you will not need a sub. They are powered and of high quality. They are also very revealing but, keep in mind these are mastering devices first and foremost.
The X-10s are awesome from what I have heard but, they are expensive - about $20K+ last time I checked. The X-10 has a pressure compensator built in and will change it's response to any volumetric change in the immediate surroundings. For instance, if someone opens the door to a studio while these speakers are playing the response or output will immediately compensate so as not to alter the response from what the mastering engineer is hearing. They are also capable of extreme SPLs.
Both these speakers can be rented and, are often acquired this way since they are expensive and, the need is often temporary or specific job related.
