Yup, me bad Bill!
I just did a little test since I had my DC power supply fired up to work on a amp.
I applyed a positive 1.5 volts to a CTS 15" Bass driver I have and it kicked the cone out over 1/32 of a inch!
This offset / new zero position for the cone probibly would have started into cutting into your Amps Bass output once , or if you where to play it at about 50 % of its output, so it's very good you got that voltage down to near zip!
