When you go to the cinema, much of the auditory excitement is generated from the low frequencies. Low frequencies cause us addiction. That's what the sound designers of a movie know. Many of the researchers of the last decades have been devoted to understanding the auditory phenomenon of this part of the spectrum and how to reproduce it in the most natural and controlled way from ever more compact cases.
Let's face it, the bass you hear in the cinema, it generates not one, not two subwoofers, it's multiple boxes with a precise acoustic adjustment according to the size of the room and the specifications of "certifying" brands like Dolby or THX.
Is it possible to have high-quality bass for a stereo audio system or a home theater? Read on.
For a home theater, the Best subwoofers is necessary, even mandatory to have the maximum sound experience possible. Recall that the movies now come encoded in multichannel 5.1 or 7.1 channel audio. This with the idea of achieving the desired wrapping. The "point 1" refers to the low-frequency channel or LFE; This is a standard on which sound design operates in all modern films around the world.
For a stereo music system, the Best 10 or 8 Inch subwoofer is optional but highly recommended.
Here are some basic recommendations about choosing a subwoofer:
1.The size of the room:
Knowing this detail will reveal to us as a first instance the size of the subwoofer required. Obviously, i
n a large room a larger and more powerful subwoofer is desirable, this has to do with acoustic questions: a larger space allows the displacement of sound waves, causing less standing waves (sounds that are "trapped" in one place causing a Sound diffuse, unclear). ASW608 26 cm x side Bowers & Wilkins subwoofer is an example of a compact box that can excite thrills without taking up too much space.
2. Determine whether the subwoofer will be in sight or "hidden."
Being a box of considerable dimensions and "usually" goes to the floor is important to consider design and decoration issues and how this box will adapt aesthetically to the room. There are also on-wall (wall-mounted), in-wall or in-cabinet subwoofers today (to be placed inside a "niche"). A subwoofer should not impede the passage and should be pleasing to the eye, which is why many brands have been concerned with making them with irreproachable finishes. Just as an example, a subwoofer that is a delight for eyes and ears is Bowers & Wilkins' PV1D, its almost spherical shape is already an icon of our times.
3. Levels of listening:
Volume is a subjective issue; many enjoy with moderate levels and other people only conform to stratospheric volume. The higher volume you want, the better the subwoofer will be. But it's not just about quantity, a high-performance subwoofer like the famous DB1 from Bowers & Wilkins allows fine tuning like almost no other subwoofer on the market. This thanks to a sophisticated digital signal processor and an acoustic compensation system for the room, which translates into a perfect configuration according to the size and conditions of the room.
4. Habit and place:
To know which subwoofer to choose, it is necessary to know what use will be made of it. Projecting the purchase of one or more subwoofers for a dedicated home theater is not the same as for an open family room or studio with a critical listening stereo system. The Bowers & Wilkins ISW-4 is ideal for those people who are building or remodeling their home and want high-quality bass reproduction to listen to their music, but they do not want any box before their eyes; It is a built-in subwoofer. For those who are about to design the home theater of their dreams, the B & W CT SW15 is a passive 15 "subwoofer ideal for placing inside a niche.
