Cinder blocks, draped with a fabric of your choice for the short term. Work on training the dog, with the recommend chili pepper sprayed onto the fabric.
The first is quick, easy, and cheap....and temporary until you've got your fur baby convinced that knocking the speakers over is not acceptable. ;) That will take time and patience....the second evaporates quickly if he/she doesn't 'get with the program' as fast as hoped....
Good luck, and enjoy your new friend. Remember the puppy you train now will be the companion you have for the rest of your days together. Make them happy for the both of you. *S*
