In this work, using the formula for hyperfine splittings, we first calculate the mass of the bottomonium member for the axial-vector multiplet (11P1). Then, the masses of the axial-vector mesons Bc1,(ss and K1B are extracted in Regge phenomenology. After that, we estimate the nonet mixing angle and the mixing angle for K1A - K1B. We suggest restudying h1(1380) near 1478 MeV and searching Bc1(1P) near 6774 MeV. The predictions may be useful for the discovery of the unobserved doubly heavy meson Bc1 and useful for understanding the K1A - K1B mixing and the axial-vector (11P1) nonet mixing.
