3 Terminals

[Ric 2001]

Bought a set of ALPHASONIK PFZ-652 full range speakers. For some reason there are 3 terninals on the back of the speaker 1 positive and 2 negative.

They sound quiet compered to my composites upfront at the moment.

Going to test the other terminal at dinner to see if it increase the performance of the speaker or not.

But in the mean time is there a reason for having 2 negative terminals?

Well swaped to the other negative ternimal and it's brought the whole system in balance.

Guessing as I'm not up to speed with ICE, but could it be a 4 ohm and an 8 ohm terminal?
