Not all home audio speakers are created equal--many pitfalls are out
there for those shopping for speakers, so buyers should beware of false
promises. For example, there is a myth that speakers that feature 7.1
Dolby Digital sound are better than 5.1 Dolby Digital. This simply isn't
true. The standard in the industry is 5.1 because only a small
percentage of DVDs support Dolby Digital in 6.1 or 7.1 capabilities.
Once this becomes more prevalent, than 7.1 will probably make 5.1
obsolete, but for now, there's no need for 7.1 since the technology
hasn't caught up. This difference can save you hundreds of dollars.
Also, just because flat TVs are popular doesn't mean that flat
speakers are better, too. The closer to the wall the speaker gets, the
higher the interaction between the wall and the speaker, causing a
greater likelihood for distortion and "flat" sound. A wider or "boxier"
speaker will add dynamic dimension to the interaction between the
speaker and the wall, causing more vibrant and robust sound.
However, one myth does that hold true is the notion that bigger is
better. While this is not always the case, generally speaking
bigger speakers provide better quality sound than their smaller
counterparts. The smaller the speaker, the less likely it is to deliver
any kind of real volume, and that applies to all frequencies. Also, a
bigger speaker will most likely have a tweeter to ensure quality
performance at high frequencies.
However, if one is determined to find small speakers that deliver
high quality sound, there are a few options available. Certain systems,
like the Bose Acoustimass Speaker System, incorporate a subwoofer or
bigger speaker to use in conjunction with the smaller speakers. These
types of solutions will improve the quality of sound that one would
expect from small speakers, but overall the performance is still
unlikely to match the superior sound of really large, top-notch
speakers.
