Bass is never a problem with Wilson Audio. In some models, such as Alexx, I find the bass is too strong but lacks texture. XVX bass is more refined and controlled. Daryl Wilson said the improvement in bass is due to the use of a new composite material which has higher damping property. He demonstrated hitting samples of new and old material, the new material is less resonate.Thanks for this description, very interesting! How would you describe the bass of the M6 in comparison wih the bass of the XVX? In reviews the latter has been particularly lauded for its impact and realism, as something that makes it stand apart from almost any other speakers.
Robert Harley for example, in his TAS review, talks about an unparalleled rendition of drums. His usual reference speakers are the Magico Q7 Mk II, I believe.
The difference between M6 and XVX in the bass section is mainly due to sealed box and ported design. XVX has more of a kick but M6 has more details. The transition from bass to mid range is more seamless in M6 as well because of uniform design from bass to mid range.
At the end of the day, it is personal preference that dictates. Wilson Audio sound is beefy and fast. Magico is detailed and refined. You can choose accordingly.
