The new wardens

[SacredTanakh 67]

Are the new wardens all out higher frequency SPL subs like the older ones? My application is more in the 24hz to 40hz range, more towards the lower end. Also it will be purely for music, no competition use, just demos. My plan is 2 warden 21s in a wall tuned to around 32, on two crescendo 3500s.

The old wardens I heard you could ask for softer or harder spiders which would change up the response. Is that also available if the stock response is too high?

Thanks
