Why don't you like Mageplanar speakers?

I owned Maggies for ten years, but moved on to dynamic speakers for two main reasons. As well as they did many things, realistic bass with "slam" was not one of them. The other thing is that they're something of an interior decorating conundrum if you don't have them in a dedicated listening room. It's hard to integrate two wide, door sized panels into a living space gracefully IMO. Also, they're picky as hell about partnered amplification if you're looking for the absolute best possible results.

Bass violin, Tuba, Organ's low notes are the instrument no Maggies will ever play even dropping the fact about 'slam'.
