Speakers

 

 

<3 types>

1. Dynamic —> E.M. (Electro-Magnetic)

2. Ribbon —> E.M.    

3. Electro Static —> E.S.F. (Electro Static Force): Usually cut off 100 & below Hz

 

*Cone drives for the sub woofer

 

 

<Speaker Installation: for 'Good' sounding>

i) Understand speaker

ii) Good room

iii) Adjust well

 

 

 

<Speaker Specification>

1. Band width: 40 ~ 18.5 kHz

 

2. Imaging

 

i) Hi-frequency: Clarity, depth, dispersion

 

ii) Mid-Range frequency

: Solid, clear, not too soft, not too edge

: Imaging should be clear, not too fat or thin

iii) Low Frequency

: Thickness, booming

Inter modulation distort (similar to harmonic distortion)

==> ∵ Separation between woofer & tweeter

 

 

 

*Most speaker systems are designed to operate to react specific frequency range

*NS 10M speaker —> Mid range sound is boosted (limit: +70 dB)

*Why fidelity of speaker system is possible?

==> Because catch only this spectrum (40 ~ 18.5 kHz)

 below 40 Hz, speakers cannot express reference (produces harmonic distortion)

 

 

*Speakers tend to be (over)compensated
