| | Stereophile: Wharfedale Diamond 9.1 loudspeaker |
 | | Fig.2 Wharfedale Diamond 9.1, cumulative spectral-decay plot calculated from the output of an accelerometer fastened to the center of the cabinet's side panel (MLS driving voltage to speaker, 7.55V; measurement bandwidth, 2kHz). |
 | | Fig.5 Wharfedale Diamond 9.1, lateral response family at 50", normalized to response on tweeter axis, from back to front: differences in response 905° off axis, reference response, differences in response 590° off axis. |
 | | In the time domain, the Wharfedale's step response (fig.7) indicates that both drive-units are connected in positive acoustic polarity. |
