First pair of Polk vintage speakers.

Hello, I'm very new and green to Polk vintage speakers. I had been looking for vintage speakers for my vintage vinyl setup. I had inherited a good amount of 1985 Nikko gear from my brother; tuner, EQ, Linear tracking turntable and a dual cassette deck. (I've wanted this gear since I was a teenager in 85, so getting it from him was awesome) The huge 400 watt Nikko amp he had fried years ago, and I ended up finding a nice little 130 watt Rotel to replace it. All I needed was a couple of decent speakers. He had given his speakers away to his kids and they destroyed them. I had an old pair of Technics 2 ways that did the job but of course I knew I wanted something better. I picked up these today for 80 bucks with the original stands they are the Monitor 10a with I think the Peerless tweeters. I've been reading quite a few posts here and it seems like I made the right choice. They sound fantastic to me. And they are in awesome shape overall. My only issue is the tweeter on the right speaker was put back by the previous owner upside down 
looks easy enough to fix. Take the 4 corner screws off and flip it? I took the 4 screws off and that plate isn't budging. Did they glue that sucker in? I don't want to pry too much and damage the tweeter or the enclosure edge. Any suggestions, or just let it be? It's driving my sense of symmetry bonkers 
Thanks

Worst case, you could remove a mid woofer and push the tweeter out from the back.
I thing you got a very good deal BTW.
With a pair that old though, I'd look into replacing the caps and resistor in the crossovers with fresh parts. You'll hear a noticable improvement. -
Yep, you'll have to remove a driver then push the tweeter out from behind. The gasket has excellent adhesive qualities.
Not clear from your post, but lose the EQ if you're using it.
Agreed on the crossover upgrades.

Leave tweeter as is, put on the grills, and consider it an exercise in self-control. :-)
Expect that there will be bumps in the road. Choose to not let them rattle you.
Polk - Monitor 10As, SDA 2Bs, LSi9s, White RTi4s, S4s, M3s, various centers.
Boston - CR7, CR6s, CR4s.
Subs - M&K V4, M&K VX-7B, JBL SUB150P, Jamo Sub 250, and others.

Thanks guys! The OCD pics were a riot, and the advice was great. I did end up removing a driver and with a some constant pressure the tweeter finally came out. Looks as if the metal plate was oxidizing
or maybe something was put there as another sealer and it decomposed. It was white and powdery as you can see in the pic. Tweeter is flipped and back in. Hit the contacts with some deoxit beforehand. Balance has returned to the force lol.
Next question: What do you guys do to remove stubborn sticky dust on these cones?
I will probably upgrade the crossovers at some point. Gonna save up a bit and get the good parts. Right now enjoying them as is. When I do it, it will be my first speaker mod, so albeit I'll be a bit nervous about ruining these babys. I actually have a line on a newer pair (possibly 10b units) So I may grab those as well.
Thanks again for your help.

When these popped up on the LetGo app (literally. The guy was still finishing the description of them and the posting still had the generic "Black and brown speakers" by LetGo) I answered him right away, knowing absolutely zero about these speakers. In between messages with him I did a little research and came upon here and figured out that they were peerless tweeters and that was a good thing. I wasted no time driving the 30 minutes to get them. He was asking $100 but I got them for 80 bucks with what appears to be original stands (not sure they do have that slight angle to them and are black) I'm very happy with them and glad they are in an original configuration. The label on the back of the driver I removed to get to the tweeter was dated 05/31/79 Ahh to be 12 again... "Looks like it's bound up, with a tight looseness...

Good deal there! I always enjoyed my experiences with the Monitor line of old. I have had two pairs of Monitor 5s, one with the SL2000s the other with the SL2500s. I got both for a combined $60, haven't used them since I got the SDAs though but miss them sometimes.
Enjoy your M10s they are good speakers.Just a dude doing dude-ly things

I'm guessing you live in Colorado?? I almost picked those up, the other set of 10's he has looks to be in good condition as well..

The cone will clean up nice BUT they will still be tacky/shiny do not try and scrub until you remove it. they are meant to be that way.
you will be amazed at the amount of dirt that will come off keep rag moist as it will try and grab as the original Windex dries.
just an FYI

Good to know! I knew that they are supposed to have some tack to them, but just wondered how you guys dealt with it. Slow and steady wins the race. These had been in his living room closet for years. He took them out of service sometime back in the early 2000's when he bought a whole new sick system from Tweeter Etc. when they were going out of business."Looks like it's bound up, with a tight looseness...

Maybe there's some unseen force that compels owners to let go of their speakers at the same time "Looks like it's bound up, with a tight looseness... Could be worse, could have been a loose tightness..."

You'll want to use a lint free, micro fiber cloth. Keep the cone wet with Windex, and keep turning the cloth until it comes clean. I usually use Fantastic or 409 on the rubber surrounds first, to get the brown oxidation off, then do a final clean wipe with Windex. As mentioned, they will be tacky when dry.

I know you guys don't. Isn't that weird. I'm close to RI so I have a mix of Boston and RI, it's quite something...

Dave i have never used fantastic or 409 windex has work fine for me but its good to know there are alternatives.

My first vintage Polks were M10's still have them, good speaker.2 channel: Anthem 225 Integrated amp; Parasound Ztuner; TechnicsTT SL1350; Vincent PHO-8 phono pre; Marantz CD6005 spinner; Polk SDA2BTL's; LAT International speaker cables, ZU Mission IC's and power cables all into a PS Audio Dectet Power center.
Other; M10 series II, M7C's, Hafler XL600 amp, RB-980BX, Parasound HCA-1500 amp , P5 preamp, all in storage. All vintage Polk have had crossover rebuilds and tweeter upgrades.
The best way to predict the future is to invent it.
It is imperative that we recognize that an opinion is not a fact. -
Again as said a few times ONLY USE ORIGINAL WINDEX. Not new and improved not w/any other chemicals and it works well. Be careful don't dig into them just wipe and wipe until clean. I had M7s and they needed a cleaning bad but after the treatment they looked new, sort of.2chl- Adcom GFA- 555-Onkyo P-3150v pre/amp- JVC-QL-A200 tt- Denon 1940 ci cdp- Adcom GFS-6 -Modded '87 SDA 2Bs - Dynamat Ext.- BH-5- X-Overs VR-3, RDO-194 tweeters, Larry's Rings, Speakon/Neutrik I/C- Cherry stain tops Advent Maestros,Ohm model E

Only on the surrounds, and only once. Once you get the brown oxidation off, the Windex will keep them clean. I only use it for the really bad initial cleanup.Home Theater/2 Channel:

I'll have to say that the 409 on the surrounds and then the windex on the cones did the trick. They were dirty girls, amazing how much crud came off!"Looks like it's bound up, with a tight looseness... Could be worse, could have been a loose tightness..."

So, I did notice that on the drivers that shiny black tack is only on the upper half of the cone. The lower half appears to have gone away over time. Sun exposure? extra dust and gravity? Or did the previous owner scrub them? all the drivers on both speakers are like that. Still sound ok as far as I can tell"Looks like it's bound up, with a tight looseness...
