We extend a classical result by Triebel on boundedness of bandlimited multipliers on Lᵖ(Rⁿ), 0<p≤ 1, to a vector-valued and matrix-weighted setting with boundedness of the bandlimited multipliers obtained on Lᵖ(W), 0<p≤ 1, for matrix-weights W:Rⁿ→ CN× N that satisfies a matrix Muckenhoupt Aₚ-condition.
