I listened to the 40s, 20s and ESLs a few weeks ago.
The 20s were pretty harsh and bright.
The 40s sounded terrific, detailed but not harsh or bright. The dedicated midrange on it versus the 20 really made a difference. They had pretty decent bass.
The ESLs sounded the best overall but the 40s sound surprisingly similar. The 40s had more bass.
The new motion series have a very nice elegant look to them.
I have not heard any monitor audio speakers.
