I get confused on the frequency ranges on speakers.
I am looking at 2 speakers right now. the Canton LE 190 and the Axiom M80ti.
Here is what their two sites have listed. Am I correct that the Canton has a larger range?
thanks for any help.
Canton LE 190
# Frequency response: 20...30.000 Hz
# Crossover response: 300 / 3.200 Hz
Axiom M80ti
Freq Resp +/-3dB (Hz): 34 - 22 kHz
Freq Resp +3dB- 9dB (Hz): 25 - 22kHz |

Yes that would be accurate if the actual results are.

...and...
the range given should be variations of +/-3db or less. That doesn't apply to all manufacturers which is where the confusion begins. Even then, a stated range doesn't tell you where the peaks and dips are which is one of the things that gives speakers their "personality". So, while the Canton looks to have a wider frequency response range it doesn't mean you will like the sound better than the Axiom or vice versa. |

Flip a coin to see if you believe stated freq. response or any other spec. I've had $9 clock radios with a 2 inch speaker claim they go 20-20,000. Also, on the high end of those measurements, I wouldn't obsess over the difference between 22k and 30k. Unless you are a superhero, and a superhero under the age of 35, you can't hear that high. |

As a designer I have to purchase drivers based on what a manufacturer tells me. Once I get the driver I test it myself. Here's an example of one that was supposed to be accurate from 100Hz to 15kHz. The color band is the +/-3db zone. The black line is the raw FR, the red line is an attempt to use a filter to tame the response.
And no, I don't use this driver. |
