If you're treating walls rather than corners where bass traps are best placed, the usual reason for treatment is to reduce/control reflections. Unless the wall surface is giving you an unusually strong reflection at around 1 kHz for some reason, the wool felt that provided that data would not be a good choice. It would change the tonal balance of the reflected sound significantly from that of the direct sound and produce a tonal shift which I think would be quite noticeable.

What you want for wall treatment is quite even absorption behaviour over as wide a frequency range as possible, not good absorption over a quite narrow range which is what that felt is providing.
