5) Power isn’t all-important.
Sure, Mr. Audio friend brags about his 200-watt-per-channel blah de-de-blah blah blah. And his system can still sound lousy. Power isn’t important unless you have a really big room to fill. Save the 100-watt-per-channel systems for dedicated home theater rooms where you want to shake, rattle and roll. Sixty watts per channel should be plenty in a family room environment. Thirty-five watts per channel is more than enough for background music.

6) Sensitivity wins.
This is the age of Mr. Sensitive. Much more important than the power capacity of a speaker is its sensitivity, which is a measure of how a speaker plays at low power. This is expressed in decibels, from about 83 to 93, the higher the better. And here’s a little factoid for Mr. Audio: An increase in 3 decibels of sensitivity is equal to doubling the power. The higher-sensitivity system will likely sound better as well.

7) Surround channels should be diffused.
That means they are meant to create ambient effects that can’t quite be localized, such as the hum of a spaceship or crickets chirping in the night. You shouldn’t be hearing your surround speakers all of the time. And you shouldn’t be able to pinpoint where those ambient sounds are coming from. For that reason, surround speakers should be located on the sides of the seating area and at least a foot above the heads of the seated audience. Many surround speakers have dual sets of speaker drivers pointed to both the front and back of the room to help disperse that sound. These are called bipole speakers. A dipole speaker goes step further and produces a sound that’s slightly “out of phase,” which you can think of as a slight delay between the two sets of drivers, thereby making the sound even more ambient. Bipolar and dipolar speakers are used almost exclusively for side surround channels.

8) More is not necessarily better.
One speaker has three drivers: a woofer for bass, a tweeter for high sounds and a midrange driver for sounds in the middle. The other speaker has just a woofer and a tweeter. The two speakers are about the same price. Which is better? All other things being equal, the two-driver speaker will likely have the better drivers, and the three-driver speaker will have cheaper ones. Moral of the story: Don’t be swayed by the notion of getting more for same price or less.

9) Try them out.
Listen to several speaker systems before you buy. And don’t just listen to the music or soundtracks the store has. The best way to judge a speaker is to hear how it reproduces the human voice. Bring CDs and DVDs of your own and that you are very familiar with. It’s a good idea to select various tracks or DVD chapters that have loud and soft sounds. Bring vocal tracks and a DVD with some really soft or whispered dialogue. Can you hear that whispered dialogue clearly? Listen to the CDs and DVDs before you go to the store, even if you’re sick of them. This will enable you to judge the speakers’ sound and perhaps pick out sounds that you’ve never heard before.

10) Buy what you like.
Don’t be influenced by “this is the better system.” If one speaker sounds better to you, go with it. You’re the one who’s going to be hearing it day in and day out. But be sure to take other things into consideration, such as the room decor and layout, and consult your electronics dealer on which system would be best for a large space with hardwood floors, for example.

That's it, these are the points you need to keep in mind before spending your money on a set of quality Home Theater Speakers. As always, there are many more factors that effect the performance of a good Speaker system, but the points discussed here in Part 1 & Part 2 will suffice for most of us. Happy hunting!
