A:Answer The general rule when selecting a sub is to make sure it has at least twice the per channel wattage rating of the receiver. So as long as your receiver can put out up to 50 watts of RMS power per channel, this will be a perfect choice. That being said, if you're looking for a home theater system to match your receiver, here are the general rules to picking out speakers for your system. 1. Make sure the receiver can handle the impedance/ohms of the speakers. Typical impedance and 8 ohms is almost never a problem. 2. Make sure that the speakers you choose can handle the power rating of your receiver. If you have a 50 watt per channel receiver, be sure the speakers you choose have a wattage rating of 50 watts or higher. 3. Stick with the same series of speaker, so that all of the speakers have the same sonic tonal quality, giving you a seamless transition when sound travels from one speaker to another. For example, if you select the STUDIO 580 floor standing speakers for your front speakers, be sure to select the STUDIO series center and bookshelf speakers for your rears.
