	N ot e s	1. Measurements are taken at 3m on-axis, 1/3 octave, unless otherwise stated.
		2. Response depends on loading conditions and room acoustics.
		3. Measured with a single boundary, 1 m from rear of cabinet.
		4. Phase variation from pure delay.
		5. Measured at 1 m, with pink noise or music.
	PHYSICAL DIMENSIONS	6. Nominal 8½ resistive load, pink noise, 100v peak.
