Hey all, i'm new to the forum and this is my first post. I'm thinking about getting 2 pairs of the 6.5" sr6500's w/ a 4 channel polk amp to run in my '05 Legacy GT Limited. From the limited material i was able to find on these speakers, the sr6500's seem amazing.

I'm really only concerned with sound quality, but i need to know if anyone owns these speakers or has even heard them. I'd probably go with the mmc5250 if they'd fit in my doors, but no luck :( Any information would be greatly appreciated. My backup option if i am unable to thoroughly research the sr6500's is the db6500's. What does everyone think of them?

I appreciate any input.

    They seem like it don't they?

    if you get the SR 6.5"s how do you figure the 5250's won't fit? hmmm depth? db's are great speakers however buy the SR's I'm sure you will be fine.

    i'm not entirely sure the SR series is in production yet. they're intended to be polk's absolute best car offering ever, and as a proud owner of their mm6 i can say with confidence that that means a great deal. if you can stand it, i'd say wait for the SRs - it'll be well worth it.

    and if they're out already and i've somehow missed the announcement - buy them, enjoy them, and after you've changed your pants come tell us how they sounded :)

    The SR6500's are in our warehouse, and soon to be released to dealers. Tweeter should have a bunch, and whatever independants that order them.

    Yeah, i'm worried about the depth, I've looked into the db6500's and they will fit with a small spacer ring, but barely.

    When you say soon, do you mean within the next week or within the next few months? I have a window of about 2 more weeks to make my purchase and if I can't get the sr6500's i'll have to go with the db's. Thanks for the info

    I would think within the next couple weeks, depending on where you are. If you're near a Tweeter ask them, they may have some in their warehouse already. If you're near another dealer of ours, ask them to call and see if they can order them yet.

    Dude, they are 3 times the price of what you can get the MMC's for. The MMC's are nice speakers. I installed a set into amulford's truck for him and they served to greatly impress. I wouldn't worry about it unless you want to uninstall and reinstall everything.

    Oh don't worry, just had never heard about them. The MMCs get better every hour and every day.

    Yeah, amulford said he could hear audible differences as they broke in. They should be good and broken in by now so they should be sounding pretty sweet. The MMC coaxials I put in a friend's Jeep sound incredible after the finally broke in.

    I figure about 60-80 hours of breakin with varying musical genres and varying volume levels should be about right. So far with about 2 hours a day in my truck, I'd say I'm about half way there.

    If you ever get tired of the MMC component speakers, you can upgrade to the popular Ring Radiator Tweeter for about $107 a set from any Vifa distributor.

    Is it a pop in replacement for the one that came with?

    The SR6500's come with the ring radiator tweeters and a better mid-range than what is in the MMC component set. It's better at least from a specs point of view. I haven't heard them yet.

    The Vifa tweeter is made with the same technology but I do not believe that it is a 1 inch tweeter but rather a 1.5 inch tweeter. The MMC's have a 1 inch tweeter. The SR6500's have a 1.5 inch tweeter.

    All the specs are on the site here. Just gotta look under the Car Audio section.

    You need to read more carefully, look again. :)

    Edit: In one place it's an inch and a half, in another its 22mm (which is less than an inch)

    22mm is the size of the driver surface not the actual size of the driver itself including mounting flanges and stuff.

    You could stick a flange on it 6" in diameter, but its still a "22mm Ring Radiator Tweeter" no matter what size chunk of plastic its mounted on, IMO.

    But you are missing the point. He asked "Is this a drop in replacement for the MMC" or something close to that and it isn't a drop in replacement. The size of the driver and it's mounting assembly is too large to fit a hole cut for the MMC tweeter.

    Yeah, I just wanted to know if it would fit where the MMC tweeter is and if it would hook up to the MMC crossover with no issues.

    I don't think the crossovers would work either. The MMC has a 2nd order crossover with a 2.6 kHz crossover point. The SRs have a crossover point at 3100 Hz but no more info on the crossover. Just the crossover point salone, I don't thin the SR tweeter would work well in the MMC set and x-over.


    Sorry, the SR has a 2nd Order Low Pass Filter and a 3rd Order High Pass Filter. Decidedly different crossover.

    It probably won't snap in to the pod that comes with the MMC. No clue on the crossover.

    the mmc xover is tuned specifically for the mmc speakers, and ditto for the sr xover... you MIGHT not blow anything up if you mixed them, but i wouldn't count on it sounding good... now, biamping, on the other hand, that'd be a good thing to do...

    and i agree, not likely to be an easy drop-in replacement...

    Actually, I think if someone were to use the vifa for the MMC combo, the x-over would be just fine (assuming the polk tweet is 4ohm). The ring radiators are flat all the way down to 800hz. I can't imagine it sounding worse. I think in this case, the crossover point is set more on the limitations of the mid-driver.

    Suppose I could buy one for the sake of "audio science" and try it out.

    I don't know. There is alot more to it in a car. You don't have control over the enclosure design as much as you do for a home speaker and the MMC has a very different tweeter. Also, the ring radiator tweeter is very directional and having it cut off at 2600 rather than 3100 Hz might show some limitations of the setup and emphasize them. Especially since the midrange and tweeter would not be very well voice matched.

    Also, the crossovers are very differe. The MMC is a second order 2-way while the SR is a 2nd order 2 way with a 3rd order high pass to make it a bandpass 2-way. That is a different beast and probably done so to reduce the directional tendencies of the ring radiator tweeter whihce would not be very desireable in a car where reflective surfaces are a hinderance more than a help.


    Also, I think you should buy a set for teh sake of audio science and then sell them to me when you are done! I'll give you a fair "used" price for them! ;):p

    The SR crossovers have a 2nd order low pass for the mid, and a third order high pass for the tweeter. Neither driver is bandpassed.

    These ring radiators are not the same driver as the ones used in the Lsi home speakers. They work much better in a car. I put in some Lsi home tweeters in my Protege years ago and they are very directional and needed quite a bit of EQ (partly because of firing into the windshield). Plus they were so big they didn't leave many spots to put them. The new, smaller ring radiator works well off- axis (as good as the carbon series tweeter), at least in the kick panels of my Civic, and the doors of my boss's WRX, and the other few installs we've done so far. And they're much easier to mount.

    The mounting of the SR tweeter and the MMC tweeters are very different. The MMC tweeter snaps into a cup, and the SR tweeter has a spider clip and trim ring. When mounted in coax mode they twist to lock into place.
