Cambridge Newton MC300 and S300 Surround Sound Speakers

How big is your room? If you're using it for a small bedroom setup, it will be sufficient. I would go 3 MC300 on the front and a pair of S300 as your surround speakers. If you're using it in a living room as your primary setup, I would consider 3 M85 bookshelves for the front and S300 for the rear. The STF-2 is a fine choice if you're using it primarily to music. For movies watching, I would start with a SVS PB10 or eD A2-300.
