Labs are great (second only to Goldens) but a young energetic puppy will still be quite large by 1,2 even 3 yrs old. A proximity buzzer might help (they really chirp not buzz). Training, yes and the buzzer can provide a "correction from the environment."
Besides that first line of defense, putting the speakers in a non-optimal spot for SQ might be good for a couple of years.
If they were dipoles, you could suspend them from a beam, but box speakers will move and cause some modulation if you do that.
A metal 'fence' around the speakers might help.
