What makes the KLH Model Five floorstanding speaker different from other speakers?

It all comes down to the Model Five’s acoustic suspension design. Acoustic suspension speakers are much better suited to deal with low-frequency program material than any other loudspeaker design. This is particularly true when listening to contemporary music. Today’s recording technology has become so advanced that artists are constantly finding new ways to use the frequency band below 40Hz. This was not the case 20 years ago. As technology has evolved, it is becoming apparent that traditional bass-reflex speakers have problems with detail and accuracy in this regard.
