Go with the db series. I initially thought the DXi was introduced to fill the gap between the db series and MM series Polk speakers. But after doing some reading recently I think the db speakers are coming out ahead of the DXi. Supposedly the DXi was introduced to be a "Best Buy" brand or a line of speakers designed exlusively for some big retailers.
For about ½ the price, I just installed DB651S (shallow mount) coaxial Polks in the dash. The stock tweeter tombstones remained, and the additional tweeters on the DB651S's filled in the high end sound I was looking for. The bass is now clear and not so "muddy" as stock.
I also installed DB651 (regular mount) coaxial Polks in the soundbar. I am happy with these, even though I have no amp and a stock 130 with uConnect. For about $110 for both speaker pairs (Amazon also) I am a happy camper. The difference from stock is night and day.
This sound will probably not make an audiophile smile, but it did the trick for me on a shallow budget.

Go with the DB's... Installed them about a month ago in mine and I love them. They sound awesome and I have no complaints. Plus, they are marine grade so I don't have to worry quite as much about a little bit of rain ruining them.
Are you guys all running stock HUs? I was shopping for fronts, to go with the Infinity 629I Kappa's I put in the roll bar. My concern was the tweeters that stick out from the Kappa's interfering with the non removable front grills (idiotic design). Those Polks look like they may fit the bill, but I wonder if 2ohm would be better.
Any problems/issues and/or tips for installing the tweeter in the dash tweeter location?
I have Polk MM in the front and roll bar and they sound great. For the tweeters, i took off the grill and used a Dremel tool to cut the hole larger for the MM tweeters. The MMs came with a cup that the tweeters sit in and i cut the hole to fit. They have a lip on the cup so it covers up any oops moments haha. It looks better than stock with the tweeters showing. Ill post some pictures after i get home from school. Also the front and roll bar speakers fit perfectly in the stock holes with the stock grills on.

Here are some pics from my build thread. I installed the MM6501 components up front and the sound upgrade is amazing. The bass is so much harder and cleaner now. No more distortion. I wired them direct to my Pioneer HU.
I simply popped out the stock tweeters and unplugged them. I taped the wire secure to another wire behind the pods.
I used a sanding bit on my RotoZip to round out the pod a little larger. It's not important to maintain an exact circle becuse the new tweeters have a beauty ring that will cover the rough edges up.
Components are always preferred to coaxials, but the way they're amped is important.
I'm not sure how the system in your Jeep is amped or crossed over. My factory "premium" system has an amp that I bypassed when installing my front component set. I ran directly to the HU and used the supplied cross overs.
When available, use components. The problem is that whack 2 ohm amp and lame 3 band EQ are still powering new spakers in the stock premium system. If you want the components to sound amazing, get a real amp. But adding a real amp means jumping through some hoops...and if you are going to go that far, you might as well add a real HU while you are at it.
Glad I found this thread! I'm looking to upgrade speakers in my 2013 jk Sahara. I'm keeping the 130 hu for now-may upgrade later.
I was looking at the polks. What are your thoughts on going with the db501 components vs just replacing the woofers with the db651s.
I'm also thinking of using the db651 in the soundbar.
Thanks for your input.
I have the db6501 components and they're excellent. I can't wait until my Tuffy deck actually turns up so I can install the amp to drive them properly. I can't tell you how good they'll be with the stock deck though, I'm running aftermarket.
Just fyi, you need the shallow mount db651 speakers for the soundbar. The standard db651 won't fit.
They fit just fine in my sound bar. I used the supplied bracket, which I drilled into the plastic sound bar. I then screwed the speakers into the bracket.
I used the db651, not the db651s.
You know what, this will teach me to just glibly trust what people like Crutchfield say. I just spent a few minutes trying to figure this out and comparing dimensions, and now I'm pissed.
You are of course correct. I had assumed that the slimline speaker was essential because the base of the magnet in the slimline unit touches the top of the soundbar, so I couldn't see how a deeper cone was going to fit. I went to the Polk website and compared dimensions, and the speaker depth of the db651 and the db651s is identical. The difference is that the db651s has a flatter profile, thus allowing the factory covers to be refitted; if you use the Polk covers, which I presume is what you have done, then there's no issue at all with using the standard db651 in the soundbar.
Given the full size speaker has a much better frequency range and slightly improved power, I'm now annoyed with myself for not looking at this properly as I would have sacrificed the factory covers for improved performance. If you're not insistent upon a stealth install, this is a better route to go.
I really wanted the DB651's all the way around, but they don't fit in front because of tweeter protrusion, and you can't really make them stealth in the rear.
If I had to do it all over again, I would probably consider DB6501's all the way around. Now that I've had the Jeep for a few months, I'm more willing to Dremel the tombstones aand put some holes in the soundbar for new tweeters. Of course, to make it sound right...that requires a new amp....and I'm not quite ready to go that far, because for me, I would go with a new HU while I'm at it.

That's correct. I should have mentioned that the non-slim version does require you to use the Polk speaker grilles.
I initially kept them silver, the way they come from Polk.
But I didn't care for the contrasting silver so I painted them flat black.
Today I installed Polk db651 speakers in the front and the sound bar. They sound awesome! I had to mod the mounting plate a little to get them to work. I was able to fit the factory covers back on the sound bar. Next step is to replace the stock HU!
(Do not get the 60.9s, their tweeters are too large for the OEM pods.) If you get the polks, you will actually LOSE volume (not clarity) because they are 4ohm speakers and the OEM amp runs at 2ohms. If you are using the stock system with the stock amp, get 2ohm speakers and as high sensitivity as you can get.
