TRC Horn Loaded Speakers
These horn loaded speakers have used new technologies to improve on classic ideas. These have perceptibly improved audio quality compared to traditional horn loaded speakers by using new formulas for the horn design. These new horns fill a loss in magnitude within the frequency spectrum of old designs. The result is a much better transition between the low and mid ranges. People who have heard these horns remark on how they never knew what was missing until they heard these. The listening experience is very enjoyable.We have also used modern computer design and manufacturing to reduce the weight of these speakers considerably. This makes them much easier for the average person to handle.
Horn loaded technology has always been the best option for reproducing sounds as realistically as possible.
There are several reasons for this:
- Horn loaded speakers are extremely efficient.
- An ipod can be plugged directly into a speaker even as large as these, and it will play loudly enough to hear it in another room. Those who boast about how many watts their sound systems use have misjudged what is important in good speakers. Although it may appeal to testosterone, it won't appeal to an ear trained to hear quality.
- Horn loaded speakers have very low distortion.
- Due to the efficiency of horns, the internal drivers have to move very little to move a lot of air. This cuts down on Doppler distortion as well as simply keeping the driver within its physical limits. Audio manufacturers have trained many of us to think that the distortion coming out of most speaker is the way things are 'supposed' to sound. The result is that those new to hearing high quality sound will almost think it odd to hear volume without distortion.
- Horn loaded speakers have a large aperture.
-
This is very closely tied with their efficiency, and basically
means that they can couple with the air very well. A horn
loaded speaker will use a little energy to move a lot of
air. It is like having a woofer that is roughly
30 feet in diameter that will be louder than you can bear with
10 watts.
Another way to think about this is to compare two lights. Say you have two light sources that are set to the same intensity, but one is a flashlight, and the other is a spotlight. The spotlight will illuminate far more than the flashlight merely because of its size, whereas the flashlight would have to be many times brighter to illuminate the same amount. The same is true for speakers. The practical result of listening to a horn loaded speaker is a much more enjoyable listening experience. A horn loaded speaker turned down will be much more easy to hear throughout a room or a hall than a normal speaker. Imagine the members of a brass band trying to play a concert with nothing but their reeds! Just as the horn attached to the reed makes it much more efficient at producing it's sound, the physics of horns make a big difference with speakers too! - Horn loaded speakers are non-directional.
- Many people would see this and argue that horns are very directional. If you were listening to these in the woods, they might have a point. The fact is that these speakers sit in the corner of a room, and turn the entire corner into one large speaker. This large speaker efficiently projects sound into the entire room. It doesn't matter if it isn't projecting sound at angles different than the corner of the room. Chances are good that you wouldn't use these in the woods, and that you would like to have your music efficiently projected into the room that you are in. The large aperture of these speaker will do this for you. And since they fill the entire room, they are better than conventional speakers. A person can stand anywhere in a room or hall with a horn loaded speaker, and be surrounded by sound. The best way to describe it is that "it's just there." You won't notice that the sound is coming out of that box in the corner; you'll just hear the music in the air.
- By design, these speakers do not resonate.
- In general, a sound system does not want to resonate if at all possible. Most of you know what a resonating sound system is, because almost everyone has been stopped next to the teenager's car which is rattling parts off in the intersection with it's bass notes. Sound systems that cannot reproduce all frequencies equally often compromise by tuning the cabinets to resonate at a certain frequency. Resonance happens whenever a cabinet starts to vibrate at a frequency that it responds to naturally. Whenever music hits that frequency, these cabinets become very efficient and loud. They do not, however, have the ability to be that efficient at any other frequency. Some high end systems must make this compromise since they are designed with other priorities like cabinet size, which make it impossible to avoid. When this happens, a skillful speaker manufacturer will balance all the other properties of a cabinet to provide the best listening experience possible within these limitations. This is why it is important for you to have in mind what is important to you when you shop for speakers. The teenager desires to loosen the parts of his car with a repeated note. Some people need a cabinet with restricted dimensions. Some people care only about the best possible quality sound. These speakers were designed with clarity and efficiency as a top priority. As a result, these speakers can efficiently produce all the frequencies that the human ear can hear.
In summary, a horn loaded speaker will easily blow your clothes around on ten watts, and still sound just as clear as they did playing softly. The conductor turning his pages is easy to hear, while cannons shots are played back with ease. The only time you won't like these speakers is when they reveal the flaws in your music collection!
