For any theater, the first thing you should not be lacking is the speakers that are situated in the center on the front of the display (in some commercial cinemas they are set behind an acoustically-transparent screen) known as the front trio.
It is comprised of two speaker fronts (right as well as left) and a center speaker that is located near the midpoint of the front plane.
Front speakers of the main stage: Use within our Home Cinema
They are located on both sides sides of the screen, and directed towards the center of the screen These speakers are successors to traditional HiFi Stereo systems. The role of these speakers in your home theater system is twofold.
On the other hand, they’ll be charged with reproducing the music we own in formats like CDs that are stereo as the A/V receivers or processors will use them as the primary speakers and then send the signals to them.
Furthermore to that, when we employ them in cinema the speakers will produce the bulk of the sound scenes, which reproduce the soundtrack and a substantial portion of the effects that are special, which are both regarded as the main (shots blasts, explosions, shots and so on.) as well as the ambient noises that place us as active.
The role of the HR department is thus crucial. The role of the spokesman is crucial members of our team, so we should pay the highest attention to them . We must also allocate an enormous portion of our budget to them.
The most important aspects to take into consideration
We can locate two fundamental models that are available such as column or floor loudspeakers as well as bookshelf loudspeakers. Which is the better option? Which option should I select? It is based on the circumstances and most importantly, the budget, as well as the dimensions and arrangement of the space.
It is recommended that they incorporate drivers that are greater than 7 inches or at minimum 6 or 6.5 to ensure that they can be capable of being able to go down to low frequencies, without distortion.
If they are well-designed the size will be able to reproduce frequencies that are at least 40-45 Hz (the interval below the point where most music is dropped) with the maximum roll-off of 3-6 decibels and the sound level or pressure that doesn’t cause distortion and provide a full sound experience without issues.
The most common thing we hear you will find when visiting the store is that they inform that when it comes to movies, or even music, it’s not necessary for speakers to decrease their frequency that much (many individuals and certifications like THX suggest cutting them down to 80 Hz) as the rest of them will reproduce through the subwoofer.
However, just because a speaker is operating at a particular frequency doesn’t mean it doesn’t have the ability to produce lower frequency (we can see this when we discuss cutting off frequencies).
Personally, I prefer having a full-range front speaker capable of reproducing all music frequencies without the need for an additional subwoofer (we’ll discuss this in a subsequent article). Actually using two of the front speakers equipped with big full-spectrum drivers is similar to having two bookshelf-sized mid-high speakers and two subwoofers however, all of them in one box.
Regarding power requirements, moderate-sized spaces (between 20 to thirty square metres) that is an RMS maximum supported power of 60-80 Watts per speaker (minimum musical power between 120 to 160 watts) will be more than enough to achieve average sound pressures around 80-85 decibels (approximately and generally, as the volume of the sound is dependent on other elements like the sensitivity of speakers as well as their impedance, their amplifier employed, the acoustics in the room, distance to the speaker, etc.)
The amount of sound tension is also a subjective aspect to consider before purchasing a speaker as there are some who prefer a moderate volume to be able to see all the details , without fatigue or risking your ears’ health.
(something that can be achieved at levels that range from 75 to 90 dB) There are also those who prefer extremely intense volumes, with high-frequency bass that shake our bodies. This is the level of which is at around 105-110 decibels .
In this instance, the power requirements for the loudspeakers (and also the power supplied through amps) will be significantly more, because we’ll require a lot more power to stimulate the transducers to reach that sound pressure.
Are they shelf monitors or towers?
The power and frequency requirements make us conclude that column loudspeakers, as they can be installed them in our space generally, are the ideal options to form our primary left and right channels.
Most manufacturers prefer two different design options (we will explore this in greater detail in a separate article) either a lot of tiny drivers that provide more pressure (for instance, three, two or 6.5-inch) for the lower frequency, or two or one, but larger (8 and 10-inches). Which one is more effective?
It is dependent on the model and design of the specific device However, in general the greater the bass driver will have a better low-frequency response and lesser distortion, as the maximum excursion range of the membrane is not greater than the operating range of linear operation.
My personal experience is that if you have the option to pick between, for instance an audio system with three or two 6-inch drivers and one that has two 8-inch or a 10-inch driver, opt for the one with the latter (at identical prices and terms and after having heard each the drivers). We should never purchase a speaker without listening to it before (or at least previously).
Are bookshelf speakers not suitable for me as front-channels? They are certainly functional, and there are a number of very good models. Their only drawback is that, as a rule they don’t have the same amount of power as column models, as they use driver sizes that are smaller (normally 6 inches, though there are models that have as high as 8 inches) and less frequently (usually one though there are models that have more).
