I have a question with regard to driver replcements for my sda 1b's. They currently have MW6509 drivers. Is it possible to use MW6501's, MW6510's or MW6511's or is there a substatial difference in these other drivers?

    I may be wrong but the 6510 is a pretty darn close match for the 6509. It is also the same driver they used in the 1c's.

    The MW 6510 is not a match for the MW 6509, Not even close.

    These are the only drivers, aside from the RD tweeters, being manufactured to support vintage products, such as, Monitor, RTA and SDA. You should print this as a reference and keep it handy for the values it contains. There are no grill parts, cables, crossovers, plates or anything else available for the older loudspeakers, unless you know the Polk G O D.

    I thought I might be wrong. But it looks like Polk still carries the 6509. So he should be good to go.
