I like your priorities in life
I listened to a lot of different types of lines source speakers and some things are always the same to my experience.
1. There is a complete immunity to standing waves between floor and ceiling, that means they will work exceedingly well in rooms where this is an issue.
2. The dynamics is unreal, because of all the drivers you will never get close to stressing the drivers, even at ear bleeding levels
3. Distortion is absent, this means you often end up playing way louder than what you think, because it is so super clean
4. Soundstage is tall, because it is just the nature of the linesource, imaging seems fine to me it’s just that problematic unrealistic tall soundstage
5. Because of tbe large number of drivers, you often see much smaller drivers that are very light, what I experience is a level of detail and resolution that I just normally don’t hear in anything else....
6. If you extend the line source to the woofer / subwoofer section you seem to get a combination of power and precision in the bass that is simply staggering, maybe.... the best bass I heard are also from line source subwoofers. Another reason why this may work so well is also that I guess they are less susceptible to resonances in the vertical plane.
Line source speakers are incredibly popular over here in Norway because of all those advantages, and they sell like ice cold beer on a bleeding hot humid summers day, but I am reluctant to line source due to 4. above
The room which the XRT 2.1’s were demoed in is incredibly troubled with standing waves and some speakers are very non-perfomant in here, but it’s no doubt that these speakers are completely unreal and something special.
