A:Answer Will they work? Yes. Ideal? No. The dedicated stand for the 805D3 (FS805Stand) has a top plate that is large enough to support the entire speaker while the top plate of the STAV24 is much smaller and better suited to something like the 606 or 607 loudspeaker. Additionally, there is no way to secure the 805D3 to the STAV24 outside of using blutac. Overall, this solution will be less secure than using the FS805D3 stand.
