What does 2-way and 3-way loudspeaker mean?
If a speaker is referred to as a 2-way loudspeaker it means it has 2 speakers in it. If it is a 3-way loudspeaker it will have 3 speakers in it.
Why do 2 way & 3 way loudspeakers have more than one speaker?
Different sound waves are reproduced better by different speaker sizes. High pitched sounds like cymbals require a speaker to move very fast to reproduce the sound, as where low frequency sounds like a bass drum or guitar require a much larger speaker to move a greater volume of air. Although you could have one speaker to do both a two-way loudspeakers breaks up the task into two speakers, each specializing in producing a specific range of sounds. This means that each speaker will do a better job of reproducing the sounds within its frequency range. (referred to as frequencies) Low frequencies usually are those below 150Hz while most speakers can produce sound as high as 20kHz
Frequency Range
Frequency Range What type of sounds
Very Lowunder 30Hz Bottom notes on a pipe organ, rumble of explosion - Subwoofer only
Low30Hz to 160Hz Bass Tuba, Bass Guitar - Woofer
Mid160Hz to 3kHz Human voice, Trumpet, Sax - Woofer or Midrange
High3kHz to 20,kHz Cymbals, Piccolo - Tweeter
Crossovers
To split the sound betwen 2 or 3 speakers, we use something called a crossover. The crossover takes the signal from the amplifier and splits it into 2 or 3 frequency ranges and sending those signals to the speaker best designed to handle those frequencies. In a 2-way speaker, the sound is split between the tweeter and the woofer. The highs go to the tweeter, the lows to the woofer.
What is the benefit of a 3 way speaker system?
3 way speaker systems include a mid-range driver. This is usually a speaker that is smaller than the woofer in the system, and gets program material in the "middle" of the frequency spectrum. This allows the system to have one speaker that can concentrate on producing things like voices, saxophones and other instruments in this range.
Does a 3-way speaker sound better than a 2-way speaker?
As with all questions involving speakers
the answer is a solid "maybe". Although it would seem that splitting the signal into 3 ranges would increase the accuracy of the music reproduction of a speaker, it depends on how well the crossover is "tuned" (setup) and several other items including cabinet design, how well the other speakers are matched to each other, the listening room and what type of sound you like.
Như với tất cả các câu hỏi liên quan đến loa thì câu trả lời chắc chắn là "có thể". Dường như việc tách tín hiệu vào 3 dải tần sẽ tăng độ chính xác của việc tái tạo âm thanh của loa, nhưng thực tế thì nó còn phụ thuộc vào cục phân tần hoạt động hiệu quả như thế nào khi được "điều chỉnh" (thiết lập) và một số yếu tố khác như thiết kế không gian bên trong xe, các loa được phối kết phù hợp như thế nào, loại phòng và thể loại nhạc mà bạn muốn.
