Toddler-Friendly Budget Speakers?


Looking ahead to our baby becoming a toddler, can anyone recommend a good pair of relatively cheap (by audiophile standards) toddler-friendly speakers? I guess the most important factor is something that won't tip over easily. Whether that means floorstanding or (bolted) standmount, I have no preference. I should add that we have a pretty small space, so huge speakers won't really work. The other factor is durability, specifically some solid set of durable and effective grilles to keep prying little fingers from the delicate driver units. I realize that's a rather difficult characteristic to find, which leads to the final factor: relatively low price. So that if they do see some damage, I can live with the loss in value. Definitely something around $1000 or under (well under preferable), used or new.

Thanks for all the various suggestions on how to approach the problem. However, I'd like to clarify that I've considered many of them already and at this point am strictly seeking speaker recommendations that fit the above criteria.

One person suggested on-walls and while that would be a great solution, installing wall-mounts are not possible at my current apartment. The other recommendations I've received thus far have been the Ohm Walshes and the Usher CP-6311. Not crazy about the former but the latter has somewhat piqued my interest. Just an update.
why not bookshelves speakers on bookshelves or wall mounts? Need not be much of a downside at all.
There is a thread that asks the question, "Does Polk make the best sounding cheap speakers"? Many seemed to concur. I think so. You might check the model numbers they recommended.
Insomniac99, Please forgive me if you already know this, but, there is a difference between in-wall and wall mount speakers.
Quad 21l2 is a great sounding, inexpensive (in context) and rock solid speaker that can be had for under $1k easily. Relatively easy to drive, great bass and a nice transparent and effortless sound.
