Speaker Asylum General speaker questions for audio and home theater. |
|
Hi there,From what I've learnt on these forums over the years, I understand that the bass (20-200hz) that a loudspeaker produces is often the most difficult to drive for amplifiers... I was wondering why exactly this was the case? A speaker has an impedence and phase curve which is generally used to determine how hard it is for an amplifier to drive it... if both impedence and phase were benign at the bass frequencies, say, they looked the same as that of the mid-range (around 2-4khz), would that mean it would be just as easy for an amplifier to drive 20-200hz as it would be to drive 2-4khz? Or do woofers at the bass frequencies exhibit characterisitcs that make driving those frequencies more difficult than the impedence and phase curves indicate?
Thank you!
Mal
