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.

214,202You need to call Polk directly and buy from them. That is the only location you can get those tweeters from.

26,308Be sure to mention you're a CP member for a discount and free shipping.

Welcome!!

101036,579nope you need to contact the Polk rep in Canada last I heard. Best bet Call Pols customer service

26There are many other drivers than these 6000 series, so hoping my updated list here will help those with RT3000p/CS1000p/FX1000 rigs. I am in the process of replacing some damaged drivers, as well as building up an inventory of spare parts for that rainy day when I need them. Parts folks over at Polk were very helpful in identifying the following drivers, and informing me what is and is not in production. Please note that they gave me both the original part #, as well as any newer replacement/upgraded part # when applicable, hence why you see 2 part numbers in some cases.

Mod, I leave it up to you if prices need to be removed. These prices are directly from Polk, for Polk members only.

26Also, if you need to have more delicate repairs done, like plate amps, there is a company in Ontario that Walter/Polk deals with, which has a limited supply of rebuilt plate amps and other items for vintage speakers. They just shipped me a rebuilt plate amp for my RT3000. But I ordered a whole bunch of spare drivers straight from the US, they have a good amount of inventory.

5541I have seen some used drivers on Ebay and also seen this driver new at some speaker repair sites.

My first question is:

Are the new OEM drivers (MW6503) the same quality as the original ones?

I know that the old ones are now subject to Magnet shift because of the old epoxy.

Next question:

Are these parameters correct?

Driver: MW 6503 Driver's model #.

Brand: Polk Driver's brand name.

Fs: 29.8600 Hz (Free air resonance)

Vas: 3.0017 ft^3 (Compliance volume)

Qts: 0.3100 Total Q

Qms: 1.7680 Mechanical Q

Qes: 0.3760 Electrical Q

Sd: 0.0130 M^2 (Piston area)

Xmax: 3.1800 mm (Cone excursion, linear)

Revc: 6.5400 ohms (DC resistance)

Znom: 8.0000 ohms (Nominal impedance)

Pmax: 35.0000 watts maximum rated power

Thanks in advance.
