When most sell home theater speakers, they often find a lot of information, but do not know how much it means. The purpose of this article is to provide a basic understanding of some of the key elements of the speakers and to provide some guidelines for the average audio consumer.
Most home audio speakers purchased today are 2-way speakers. This means that the speaker has a low or bass sound woofer and a high-level tweeter. There are also 3-way speakers that add an intermediate class and these can be made clearer, all the same. However, for most people, a good 2-way speaker is good.
The home audio speakers are typically either in rectangular or circular design. Round ceiling speakers are ideal for background music and rectangular wall speakers are ideal for surround sound systems. Having said that, built-in speakers are often not only practical to install in a particular room due to room layout and furniture.
One of the problems with round ceiling speakers is that they basically send the sound straight down below them instead of out of space or the most desired area. However, some speakers offer angled woofers so you can install them in the corners, for example, and still have the sound directed outward in the room.
Typical speaker sizes are 5.5, 6.5, and 8 inches. The 8 inches generally have stronger bass with the larger woofer. 8 inch speakers are recommended for surround sound and 6.5 inch for background music. I would not recommend 5.25 inch speakers except very small rooms.
An audio voicemail speaker helps to manage small spaces where there is not enough space to place two speakers. The dual voicemail speaker provides both channels from the amplifier and these can be quite practical in bathrooms, for example.
Power rating of speakers always gets a lot of attention, but often too much attention, because the power is a factor among several others. In fact, most people rarely use the full power of most speakers because they would soon be deaf if they listened to music at peak power. Power is rated in two ways; RMS and Peak. RMS means essentially the volume that the speaker can handle all day without distorting. Peak is the highest power level that the speaker can handle before it blows. For most in most homes, 40-50 watts RMS is good. Some speakers only indicate their Peak power rating and usually Peak value decreases by 2 to estimate the RMS value.
The sensitivity rate should be 89 db or more is the usual recommendation. This specification has to do with how clearly the speaker sounds, and under 89 db, sound security may be poor.
Range or frequency response represents the speaker's low and high end range. Here the low-voltage area is the most important of the two, and usually 45-50Hz is the low part of what most of us can hear. In the high end, most speakers today exceed what we can hear and usually they are 20 kHz or more, which is far beyond what we can hear.
A speaker must share the signal that comes into it between the tweeter and the woofer. Crossover is in fact a filter that performs this function, but when the audio is divided, there will be some signal loss. A crossover of 12db is the most common today, and again it's good for most. Most speakers use passive intersections, but some advanced speakers use active intersections that are more sophisticated and allow adjustments. Few homeowners need speakers with active transitions or want to make such adjustments.
The materials that woofers are made of are often quoted in speaker specifications. Polypropylene is the most common material used and is okay, but bass sound will not be as full as other materials. Kevlar, fiberglass or aluminum woofers will cost more but offer stronger bass end sound. For real audio files with lots of money, there are other highly specialized materials available, but again, just not needed for average listeners.
You will also find that some speakers today have bridge mount tweeters and this could be a plus. Bridge Mount Tweeters do not interfere with the Woofer wife and therefore will not interfere with the woofer-low-end sound. This is not to say that there are no good speakers who do not bridges mount their tweeter as there are such speakers where very few people could tell the difference.
Speck prices today are quite remarkable. The truth is that you can buy a decent pair of ceiling speakers for as little as $ 40 and you can buy a good pair for $ 200. Some people want the best and you can find them for as much as $ 1500 per pair. As always, to some extent you get what you pay for.
