+{{Classic icon}}{{Model I icon}}{{Model II icon}}
+The Classic / Model I / Model II output for the B1s is
+* 125 Watts into 8 ohms (single B1)
+* 250 Watts into 4 ohms (two B1s)
+Hilmar-at-Bose tells us:
+If you have two sound source that are
+* relatively small
+* not driven very hard
+* you look only at relatively low frequencies
+Then you get 6dB more sound pressure level (SPL) from 2 as compared to one.
+Our B1 is a good example for that:
+* 2 B1s give 6 dB more than one.
+* You gain 3 dB by simple doubling the electrical power (250 Watt for two, 125 Watt for one).
+* The other 3 dB are gained by doubling of acoustic volume, cone area and close coupling between the speakers.
+To get the same SPL (as 2 B1s) from a single B1 you would actually have to hit it with four times the power (500 Watt).
