The Infinity IRS Betas were hybrids, ribbons for the mids and uppers and 8 cone woofers for the bass. They were very very good but did not go loud at all and strained when opera divas hit the high notes. Also, percussion instruments did not go well if turned up at all.
Before that I had B&W 801 s and those were great stuff as well.
I found no weakness in the Wilsons. One thing is because they matched my room well out of the box (crates). Even better is that they can be tuned any number of ways by varying the resistors in the back.
A big mistake may be that many listen to them with the grill covers on. They are dead compared to the sound with all the covers removed, including the one on the upper back side.
When you turn them up loud as I do some times, you can do so without straining them to levels you can only imagine with other high end speakers. This was important to me, as well as the ability to play at very low levels as my queen uses.
