@eagletennis30 - Very welcome. "Auxetic 2.0" is just the advertising/marketing coin-phrase for the latest generation of Head models, that all have Auxetic material in the graphite layup, now located in
both 1) the upper-throat/bridge/6-o'clock hoop area (which was present in Auxetic 1.0) but now also the handle area (uniquely present in Auxetic 2.0). As
@AndrewUtz referenced, the material is supposed to add stability and solidness on impact, and it actually does do that to some degree, but as a downside, it also tends to mute the feel, doing so to a higher or lower degree depending on the silo, with the Speeds probably somewhere in the middle (not the most muted, nor the least).
That said, with the Speeds in particular, that moderate muting is usually nothing that can't be overcome by using more
crisp strings – for most intermediates, that would be things like synthetic guts with durability wraps (ex: Gosen OGSM), certain multifilaments (example: Tecnifibre Multifeel), natural gut and/or poly hybrids using metallic-colored poly's (but if you're a lower-level intermediate, I would probably minimize or avoid poly altogether).
