Mounting options for Pioneer sp41/21's

Hey Guys,

I'm looking for some wall mounting options for my Pioneer sp41/21 setup. The speakers are on the bulkier side for bookshelves and my newly renovated basement has in-wall speaker jacks roughly 5 feet from ground (Pioneers just became available in Canada a couple months ago and I had smaller energys in mind when designing).

I realize I may be stuck with stands for the 41's, but has anyone mounted the 21's??

Thanks in advance.
