For sale is an Unbranded B16R85PR-05HW Poly Cone 6.5" 6.6ohm Mid/Woofer. This was used as a drop-in replacement for a Polk Audio MW-6502 Driver from a Monitor 4 - Series 2 speaker set. The 6502 is 8ohms and this is 6.6 but it sounds fantastic with the original Series 2 crossover. Whomever replaced the 6502 with this one stuck the label from the original Polk driver to this (See Photo) but it looked nothing like the original so I peeled it off to reveal an unbranded mystery speaker that sounded better than the Polk. This is definitely high-end (Humbly, I have a very good ear). I did find its 4ohm little brother going for about AUD$70 + AUD$100 postage in the US but again, no clue as to it's brand and it was selling untested. Long story short, it's a beautiful sounding driver.
