@imhififan ,
Nice suggestion, but I would be a little concerned if the OP's speakers are very heavy(-he/she doesn't mention the model). Using a screw hole to support a heavy object might damage the wood if it encounters any twist or uneven load. That was the reason I was asking if there were threaded inserts.
Seeing how there are holes for the phillips screws, I would just enlarge them and install some threaded inserts, if there is sufficient material available. Gluing those into the cabinet should provide a better fastening option whether he decides to use a threaded spike or add the aluminum bar you suggested.
