quick polarity question (1 Viewer)

[Jason Wilcox]

OK so i got the urge to take my measly JBL 8 inch sub apart and polyfill it to make it a little less boomy. so i disconnected the sub and forgot which connection is negative and which is positive. i tried a AAA battery to see how the driver would react. i put the sub back together with the driver connected (the red wire is positive right?) so that when the battery was used it would push out. if you can understand what i'm trying to say, did i end up hooking it up correctly?

Depending on where the sub is relative to the mains, reversed phase may be better. If that sub has a phase switch then it makes no difference since you can use the switch to (in effect) swap the wires.

Jason.

The standard is (and has been for many years):

When a positive voltage is applied to the + terminal the cone should move outward (away from the magnet).

However not all manufacturers (for reasons that baffle me) adhere to this.
