Polk SB1+ power adapter specs help!

I have contacted Polk directly but no answer in more than a week so I am reaching out here. I am looking for the specs on the power supply for the soundbar of the SB1 plus.

my soundbar has gone MIA and I'd like to find an adapter out of my box of them which might work.

So I'm looking for:
Voltage (24v?)
Amperage (2.5A?)
Polarity (plus inside?)
Plug connector size (5.5 mm OD, 2.5 mm ID, 9.5 mm length?)
