	This is based on the design goal that “You should always sound the same; no matter how much Bass stuff is attached” I can try to explain my view of why this is a good design goal (of which you may disagree) but let’s look at the actual behavior first.

	~~=== Without Bass Line~~ out ~~===~~		The behavior of the bass line out and B1 Bass Module outputs on the {{Classic}} and {{Model I}} are based on the philosophy that adding {{B1}}s should give the user more dynamic range (can play louder) but should not alter the tone of the instrument, including tone adjustments made using the {{R1}}, the {{T1}} or other tone-shaping equipment.
	* 1 x B1~~: 40Hz-180Hz, B1 specific EQ, some nominal gain~~ that ~~we call 0dB~~
	* 2 x B1~~: 40Hz-180Hz~~, ~~B1 specific EQ~~, -~~6dB as compared~~ to ~~nominal~~		This philosophy is notably different from other manufacturers, who take the approach that it's okay (or desirable) that adding more bass speakers causes the instrument tone to become "bassier".

	~~===~~ With ~~Bass Line Out ===~~		With this philosophy in mind, here is how the bass line out and B1 outputs work.
	* 0 x B1 connected to Power Stand: 40Hz-180 Hz, ~~flat, roughly~~ the ~~same gain as 2 B1~~
	* 1 x B1 connected to Power Stand: 40Hz-180Hz, B1 specific EQ, -6dB as compared to nominal
	** If you use a {{A1 EB}} this is a total of 3 B1s
	* 2 x B1 connected to Power Stand: 40Hz-180Hz, B1 ~~specific EQ, -12dB as compared to nominal~~
	** If you use a {{A1 EB}} this is a total of 4 B1s

	~~What this complex behavior does~~ is the ~~following. No matter if you attach 1~~, 2~~, or 4 B1s, you will get pretty much the same balance between all combined B1s and~~ the ~~L1s. It’s a little off for 3, 5~~, 6~~, 7 & 8 B1s, but still reasonably close.~~		=== No cable plugged into the Bass Line out ===
			* If there is 1 x B1 connected to the B1 Bass Module output on the PS1: B1 EQ, bass signal gain = REFERENCE LEVEL
			* If there are 2 x B1 connected to the B1 Bass Module output: B1 EQ, bass signal gain = REFERENCE LEVEL - 6 dB

	~~It’s true that~~ the ~~user doesn’t have to re-EQ our systems if~~ you ~~add~~ more ~~B1s or even a PackLite with another pair of B1s~~. ~~But that’s unique to our system, because we were actively measuring~~ the ~~number~~ of ~~B1s attached~~. ~~So re-EQ is required~~, ~~but~~ the system ~~is doing it~~ by ~~itself without any user involvement required. <ref>Hilmar-at-Bose [http://bose.infopop~~.~~cc/eve/forums/a/tpc/f/3976055944/m/9641017814?r=8691027814#8691027814 Third Party Woofers]</ref>~~		Why? Because when you add a second B1, if you did not change the signal strength you would get 6 dB more bass relative to the mids and highs. This would alter the tone of the instrument. To keep the tone the same, while still allowing the more dynamic range (system can play louder by 6 dB) the signal level must be reduced by 6 dB.

			=== Cable connected to the Bass Line Out ===
			* If there is 0 x B1 connected to B1 Bass Module output on the PS1: flat EQ on Bass Line Out, bass signal gain = REFERENCE LEVEL - 6 dB
			* If there is 1 x B1 connected to B1 Bass Module output on the PS1: B1 EQ on Bass Line Out and B1 Out, bass signal gain = REFERENCE LEVEL - 6 dB
			** If you are using a {{A1 EB}} this is a total of 3 B1s (2 on the A1 and 1 on the PS1)
			* If there are 2 x B1 connected to B1 Bass Module output on the PS1: B1 EQ on Bass Line Out and B1 Out, bass signal gain = REFERENCE LEVEL - 12 dB
			** If you are using a {{A1 EB}} this is a total of 4 B1s

	=== With More Than 4 B1s ===		=== With More Than 4 B1s ===
	~~A little more insight. <ref>Hilmar-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/3976055944/m/9641017814?r=4081020914#4081020914 Third Party Subwoofers]</ref>~~		The PS1 does not measure the exact number of {{A1}}s, so there is a slight error if you use anything but 1,2, or 4 B1s.
	~~We actually can't~~ measure the exact number of ~~PackLites~~, so there is a slight error if you use anything but 1,2, or 4 B1s. ~~For 6 B1s you will be 3.5 dB bass heavy, for 8 B1s it'll be 6 dB.~~
	~~However, these are rare cases, and if you go through the trouble to hook up 8 B1s, I guess you are actually looking for something more bass heavy.~~

	~~Don't ask how I know.~~
