My SRS 2's had a frozen dimensional driver, a 6510.
The guys here saw some Polk 6510's on Ebay.
I won them, and they arrrived today.
They look different, and have no where near the excursion of my stock 6510's.
Even have a different dustcap!
They say MM 6510 on the back.
WTF are these drivers, and if the are wrong, WHY would Polk use so close a model designation to the original 6510 ?
