I bought a pair of Equator D5 Studio Monitors for the Kemper and I absolutely love them. I went with the D5's, Carrying Case , Isolation Pads and 2 six foot XLR cables for $349. The Carrying Case turned out to be a great fit for the Kemper. It's a nylon padded bag with double zipper and it's a perfect fit for the Kemper. It has double handles that Velcro together and a separate shoulder strap. You can buy the Carrying Case on it's own for $34.99. The padding isn't real thick, but I think it would protect the Kemper just fine unless your really careless. I'm pretty particular about protecting all my gear and I think it works great.

By the way, the Equator D5's come with a 60 day no questions asked return policy. I highly recommend the D5's. The Equator D5's are only sold direct.
