Earlier, in the seventies and eighties of
the last century, it was believed that the more loudspeakers in a column, the
better. The modern approach to the organization of sound premises somewhat
different distribution of Dolby Surround system with separate subwoofer
somewhat shaken confidence in the optimal speaker sound with multiple speakers,
but the fans have left quite a lot.
The question of what should be the dynamics
of the speaker, care about developers and technologists from the moment when
the electromechanical transducers came into life. There is a certain
contradiction in the requirements to the diffuser. On the one hand, to lower
quality playback, the bass spectrum it must have a sufficiently large size and
massive magnetic coil to "swinging bass" leaves most of the power. On
the other hand, the high frequencies require maximum ease and minimal
oscillation system inertia.
Ultimately, developers acoustic accessories
came to the logical decision: in the column have jointly working woofers and
so-called "tweeter". However, in this case it formed "dip"
in the middle of the spectrum, but this problem is eliminated by adding the
third loudspeaker operating in this range.
Frequency response is aligned with the
entire audible band. The subwoofer can be operated without additional filters,
but in order to reduce the burden on him and extend the longevity, it is
equipped with a series-connected inductance, do not miss the middle and high
waves. The middle loudspeaker is also relieved of the need to "shoot the
breeze" on bass and upper signal components.
Modern subwoofer is a complex
electromechanical device. Proceedings of the diffuser are pretty big. To
provide it for a long time, materials needed to withstand elastic deformations
and thus retain its properties. BTW, you can buy the portable super bass speaker at Banggood. Besides, you can easily get other computer
and Networking accessories (e.g. USB 2.0 TV Adapter) there with high quality and reasonable prices.
