Investigating the potential benefits to both the objective and subjective performance of a two-way loudspeaker obtained by using a wide-band 'tweeter' to place the cross-over at a lower than usual frequency

摘要

The tweeter in a two-way loudspeaker was replaced by a unit having a natural bandwidth of 300 Hz to 20 kHz. This gave a much greater degree of freedom to the choice of cross-over frequency than would normally be possible. The first part of this paper looks at the potential benefits such freedom could bring to the acoustical performance of the loudspeaker. The second part reports results of early listening tests, which were conducted to discover the most preferred cross-over frequency in the range 700 Hz to 3 kHz.
