1.-electrical impedance (solid) and phase (dashed). (2 ohms/vertical div.)

2.-cumulative spectral-decay plot calculated from the output of an accelerometer fastened to the cabinet's side panel level with the lower woofer (MLS driving voltage to speaker, 7.55V; measurement bandwidth, 2kHz).

3.-acoustic crossover on tweeter axis at 50", corrected for microphone response, with the nearfield responses of the port, woofer, and midrange plotted below 400Hz, 350Hz, and 450Hz, respectively

4.-anechoic response on tweeter axis at 50", averaged across 30° horizontal window and corrected for microphone response, with the complex sum of the nearfield responses plotted below 300Hz

5.-lateral response family at 50", normalized to response on tweeter axis, from back to front: differences in response 90–5° off axis, reference response, differences in response 5–90° off axis.

6.-vertical response family at 50", normalized to response on tweeter axis, from back to front: differences in response 15–5° above axis, reference response, differences in response 5–15° below axis

7.-step response on tweeter axis at 50" (5ms time window, 30kHz bandwidth).

8.- cumulative spectral-decay plot at 50" (0.15ms risetime)
