mw6510 vs mw6500

[11tsteve]

i needed a new driver for my 11T's and found one on Ebay. however, after i received it it has become confusing.

it was advertised as a BNIB MW 6510. it came in its original Polk replacement parts box, which is labelled MW 6510. the speaker itself has 6514 blacked out and a white sticker on it labelled 6500.

of course, in my excitement to find a new driver, i did not examine the photos close enough and did not see any of this until i received it.

http://www.ebay.com/itm/170829329298...84.m1497.l2649 is the ad.

if it were a 6500 not a 6510, how far off are they? i have been searching for specs for a while but can't seem to find any for the 6510.

thanks

It's certainly not the only spec that matters, but I'd start by putting a meter across the terminals on your new driver and one of your originals to see how the DC resistance compares. Polk is well known for using up all parts in the bin, so it's not shocking to see the 6514 crossed out with a new sticker applied, but to then have a 6500 in a 6510 box? I'm curious as to what you've got there.

If you decide it is a 6500, you shouldn't have any problems selling around here to someone in need (once you rack up an additional 35 posts! )

good point with the meter.

the seller said he opened to box just to take pictures for the sale, and the invoice says..."Item # 8D0610-A15 Driver MW6510". so this is all very odd.

i wish the drivers in my speaker looked as fresh as this one. i wouldn't think it would be around long should i try to sell it.

[11tsteve]

ok.... just got off of the phone with polk... i must have gotten the new guy. i asked if he had specs for the 6510, which he didn't (because i have found specs for the 6500 here). i asked how to test with a DMM and he said test watts, kilowatts... voltage... it was confusing.
i have an invoice, but it seems of no use. i was really hoping someone would be able to help.

i am also kinda clueless with DMM usage, but want to learn, so if i could get exactly what to test to compare values with the old driver, i would greatly appreciate it.

he also told me they JUST got a shipment in of a direct replacement driver for the MW-6510 ... pt. # RD-6519-1.

i am leaving for Milwaukee this morning to see family and catch a ballgame, and i may just order a new one and figure this thing out later so i can sell this confidently.

[TennMan]

Instead of asking all that technical stuff, why didn't you just ask him if the MW6514 is a direct replacement for the MW6510?

[11tsteve]

well i have an invoice, a box, and a driver. all of them together identify this as three different speakers.... and the 6514 has been crossed out and a new sticker id's it as a 6500, which isn't even the right(or same) speaker that i need.
i am not really sure what that info would do for me. meaning, someone telling me the 6514 is a replacement model still wouldn't give me any confidence.
the 6503 was a replacement model, and it spec-ed differently... so, it seems testing would be the only way to really find out where i am at.

[TennMan]

Here's the way I see it. The eBay seller clearly advertised a "POLK AUDIO MW6510 WOOFER SPEAKER DRIVER New In Box!" and sold you something different. He owes you a genuine MW6510 as advertised.

Just because he gave you a 6510 box and said he "accepts no returns" doesn't mean you should be stuck with a speaker you can't use. I would contact him and try to work it out. I'm sure he is proud of that 100% feedback rating and would be willing to make things right with you to protect it. If he's not willing to do that, contact eBay and leave negative feed back as a last resort.

BTW, you paid way too much for the driver but that is your fault.

[Joe08867]

I agree 100% with TennMan on all counts. You need to get the seller to make you whole or refund you the money.

You also need to call Polk and get replacements from the source.

PS, never buy any speaker without seeing all the details in the picture. He false advertised these by not showing the back of the speaker. I would put a claim in with Paypal if the seller doesn't work with you.

[F1nut]

That's one of the "Made in Mexico" drivers, it's not a 6510, the 6500 and 6510 specs are not close and you paid too much.

There is a pic of the back, which clearly shows it stamped 6500.

well, here's how i see it...

the seller, who is not an audio person, has a box and an invoice clearly marked MW 6510, and most likely would not know to look at the back of the speaker.
the seller clearly posted a picture of the back, which i did not examine. it is my fault that i did not see the conflicting markings. i HAVE been in contact with the seller, who has done everything he can to give me all of the info he has, and i do believe he would issue me a refund if i asked.
but i don't think that would do anyone any good as it would just go back on the market without anyone know what it really is. i might as well take the time to see if i can figure it out, and if i can't use it, re-sell as what it really is so nobody else has to deal with this.
i also know what i paid, and its my money. if you would take the time to look, you will see i posted asking about prices, and i knew the going rate was around $50. but at the time Polk only had the MW-6503, which i did not want. being that this was a BNIB out of production original driver, i figured $10 was no big deal to keep my RTA 11Ts all original.

[11tsteve]

That's one of the "Made in Mexico" drivers, it's not a 6510, the 6500 and 6510 specs are not close and you paid too much.

so the Made in Mexico drivers are a different breed? are they inherently inferior? that could change my attitude i guess.

If you are happy with getting screwed then I'm happy for you.

I came here to gte help, not for a confrontation and to be called stupid. So... thanks for that.

[heiney9]

If it is in fact an MW6500 it is not electrically compatible with the MW6510. Sell it, return it, put it in a drawer.....whatever and get a proper MW6510.

Now as to whether it IS a MW6510 with a MW6500 sticker, I don't know exactly how you'd tell without measuring it in the circuit, which is not something a novice is probably capable doing.

Sir, I'm not trying to be confromataional. I was trying to help. I don't think anyone is calling you stupid. I'm not. I gave you good, solid advice and you thumbed your nose at it. I do think the seller is screwing you and you are trying to justify him doing it.

What difference does it make that he sent you a box and an invoice with MW 6510 marked on them? You can't use those in your speakers. It appears to me he put a MW 6500 in the new 6510 box and sent it to you hoping you wouldn't complain. The bottom line is you should have gotten the MW 6510 that you were promised!!

It is illogical to think this was your fault because you failed to see a marking in a photo that has to be magnified just to read it. You should be able to rely on the information in the text he supplied in the eBay ad that clearly described the driver as a MW 6510. If you can't rely on that description then he is scamming you.

You say the seller "has done everything he can to give me all of the info he has". That's all fine and dandy but his obligation is to supply you with a MW 6510 driver, not more information.

You seem to reject the idea of getting your money back based on a fear that the seller will put the item back on eBay and not disclose what he is really selling. That is just irrational thinking. You can't take it upon yourself to police what this guy does on eBay. You should demand your money back and if he wants the MW 6500 back he should pay for return shipping. He should not be rewarded for taking advantage of you!

[Joe08867]

Nobody called you stupid. We told you the truth. I once again agree with TennMan (Twice in one day).

Get your money back, buy the correct one from Polk and pocket the change. Its a win, win for you.

[11tsteve]

I apologize for reading too much into certain posts. I was rude and am sorry.
The seller has always been receptive to a refund which is why I didn't feel like I was being screwed. And now that we have reasonable certainty it is not a 6510 he has agreed. Meanwhile I have ordered a new rd-6519-1 replacement driver from polk.
Last question... Do these Mexican drivers have any value? He would like to know.

Thanks

Steve

I don't understand the question? If someone needs a MW6500, then I'd say there is value there. The Mexican part has nothing to do with it. That driver is stamped 1993 and still made in Mexico.

sorry. F1nut said it was a Made in Mexico driver, I thought imply ing it was somehow different or inferior. Just making sure.

[heiney9]

Hmmmmm....either way it's fine and let the seller worry about it. Get your refund and find another MW6510 or buy one direct from Polk.

Good luck

[F1nut]

It's not inferior, however it is different as it doesn't have the exposed wire leads that the originals do.

[11tsteve]

refunds in the works. Already ordered a driver... Post 18. Thanks for your help.

yes the 6503 was being sold as a replacement for the 6510, but the rd-6519-1 just shipped into Polk yesterday, and is their new offering as a replacement for the 6510.

[Schurkey]

the rd-6519-1 just shipped into Polk yesterday

Shipped in from where?

First Guess: Not Mexico
Second Guess: They come in a similar white box with no COO markings as the RD0-198 tweeters I bought.

[agfrost]

How many of your posts are on that exact same point, Schurkey?

[11tsteve]

well I guess I didn't ask Polk Audio where they are getting their drivers. The tech simply told me they had just gotten a shipment in of new replacement drivers for the 6510. And I too just got some rdo-194s two weeks ago.
I guess I don't know what coo markings are and I am missing the point of what you are saying.

It means Country of Origin [COO]. Don't worry about it. It is something that is way beyond our control most of the time. It would be nice if we could always buy USA, or at least know for sure where our money was going, but that is not always possible with China, Mexico and other countries flooding the market with inferior copies of the products we need.

[Schurkey]

Last I checked, it was illegal to not provide COO information on imported products to the consumer. And yet, it happens quite often that neither the box nor the product is marked.
