Vintage Polk Drivers

What's the difference between all the 6500 series drivers? Is assuming that higher numbers are newer and thus better an accurate assessment?

What drivers are in Monitor 10B's?

I ask beacuse I noticed that my rta12c's have 6501's and my monitor 5's have 6502's.

THANK YOU!:)

The 6511's and 6503's are 4ohms nominal. The rest are 8ohms

Edit: I think 6509s are 4 ohms also.

The attachment in this thread has a listing of the drivers in many of the vintage non-SDA polks.

Thanks man! I looked through those schematics breifly but didn't see that replacement parts list, otherwise I wouldn't have posted! When I go to that post through the link in yor post and then click the attachment it won't open, but if if go to through the parent thread to it it does open:confused:

are any better than others???

Different driver specs for purposes, nothing to do with older, newer or better, worse.

fair enough. well what about mixing drivers, not in the same speaker, but, say, in the same home theatre setup. I know that matching the tweeters is more important, but can mis-matched drivers sound bad? For example: rta12c's (6501's), monitor 5's (6502's), and monitor 10's (6503's). Is that combo less than ideal because of the different drivers? BTW they all have sl2000's (soon to be rd0's if I can save the loot). THANks!!:)

Polk sometimes mixed drivers in the same speaker cabinet.

The later SDA's had better drivers, in that the voice coils were wound differently. It makes sense that an MW6510 or MW6511 is slightly more up to date than say an MW6500X or MW6501. Baskets and materials are obviously the same.

BUT, that doesn;t mean you can innerchange all the drivers with different models, beyond just matching the ohms. All the MW drivers have that similar Polk sound but I would use whatever driver was originally used. You could call Polk an they could tell you what the next best model to use is, if you can't find an original.

10 ohms I was told from Polk CS. (for the 6509).

That would work perfectly.

Sounds about right. I measured dc resistance on the eight 6509s I have; lowest was 8 ohm, highest was 9.5.

Kinda disappointed in the wide range; I had expected them to be tighter tolerance.
