KLH Speakers: Model 20 Vs. Model 17

Buy the stereo or amplifier before the speakers.

KLH models 17 and 20 are both older sets of speakers from the 1960s and 1970s. The features and characteristics of KLH model 20 differ very little compared to model 17. However, they do have one important difference.

Similarities, Differences

KLH models 20 and 17 both have the same dimensions and the same sized woofers and tweeters, according to aphenos.net . However, it indicates that the impedance is four ohms for mdl. 20 and eight ohms for model 17. The model 20 speakers also tend to be somewhat older, compared to model 17 units.

Significance of Ohms

The main importance of the ohm rating is that manufacturers design some amplifiers for eight ohm speakers and others for 16 or four ohm units, according to Preston Electronics. Because of this, the wrong speakers may damage the amplifier or produce poor-quality audio.

Considerations

When comparing KLH model 20 and 17, the most important factor is the correct ohm level of the amplifier or stereo. The model 17 speakers may remain in better condition or last a bit longer because production ended later than it did for model 20.
