I have two 6.5" speakers, no numbers on the back...just sr142/17 on the surround in front???? My other Polks have the same # just differing series of dots before and after the #
All all the 6.5" speakers the same just depends on the application/crossover set-up?
These came in a pair of AR TSW 410s that I picked up for cheap...just curious...inquiring minds want to know. TIA, Preston
