Using Loudspeaker Properly

Page 1 of 

Now that it is known no speaker manage to produce all the frequencies needed, then what to do to overcome it? How to go about?

It was found out that certain speakers are only good for certain ranges. Therefore a concept of using multiple speakers to compensate each others short-coming is improvised.

e.g. a woofer with a midrange and a tweeter in conjunction with a X-over.

Woofer = Low Frequency Transducer.

Midrange = Mid Frequency Driver.

Tweeter = High Frequency Speaker.


This solution is not without compromise and penalties. When two or more sources are together they produce INTERFERENCE. 

However until today, there are no better solution and the multiple speakers configurations are still being used.

The INTERFERENCE will be ignored for most part, because it exists no matter what. Still the very existence of this effect cannot be ignored during listening test, case study etc.

An example of a woofer, mid, and tweeter's frequency response.

Please note that the woofer, mid and tweeter is properly selected. Else the tweeter may be a high-mid as explained in ONKYO.

Or that the mid is a pure high only, etc etc etc.

Matching woofers to mid to tweeters is an extremely difficult case. Often one out of the three will always be unable to match.

Now that the understanding of the origins of multiple way speakers is established, we'll proceed to discuss how to further optimise them together.
