    Good point,, especially if you are gonna' install Larry's rings,, and dynamat,,etc,, there's no excuse,, since the wiring schematics are posted on this site and the help/support of others here.Good luck and keep us posted.:)

    You said a mouthful Georgie boy!!! I was lucky with my 1.2TLs they were mint when I bought them and everything was just perfect wiring and all.

    It's really is a bummer that some get out of phase wiring, incorrect wiring etc!

    My drivers do that. They push out then withing a second return halfway then when i let go of the passive they return all the way. Is that normal?

    Sounds okay but I always went by the 3 to 4 second return of the MW WITH the PR still pressed in.

    I've owned 3 pairs of SDA's, and every pair, including my current 2.3tl's had one or more drivers wired out of phase.

    WOW!!! That would drive me crazy!

    I was the original owner of my 2A's. They were serviced at a Polk authorized center after about 10 years, and they wired both mid's out of phase. I also had a pair of SDA1's, I think B's, that had one mid in each cabinet backwards. And then, about a year ago, when I started modding my 2.3tl's, I discovered that the middle 2 stereo drivers in the left speaker were out of phase. It's definitely worth the time to make sure they are correct. Otherwise, anything else you do could be a waste of time.

    When releasing the passive make sure the smaller drivers are returning to their rest positions and not being sucked in by the returning passive. As the passive is pushed in it will push the smaller drivers out, likewise when the passive is released it will pull the small drivers in. Looking at the above quote mine would fall into the same results.

    Huh?

    Return to what, full rest or halfway?

    When it is said half way on the return, it sounds like to me they are returning to full rest, so when you release the passive, it will draw the mids into the cabinet giving the illusion of looking like they are returning to full rest.

    I see. No, they do not return to full rest until the PR is released at which time the drivers will "suck in" past full rest by the very slightest amount, so slight that one might miss it. They then return to full rest.

    Let make this a little clearer as my definition of "full rest" doesn't seem to coincide with what Jesse was asking.

    By full rest I mean the MWs stop backing in after 3 or so seconds. They DO NOT go all the way back in until I release the pressure from the PR.

    Hey all,
    I know this is a very old post but after reading this post I now have a question. when I just did my mods the other day,I noticed something very odd. Since I never had my 3.1's totally apart before let me say this, I thought positive (black) goes to positive? And white is negative? Well let me set the stage... I have 4 midwoofers just like the big boys but only 1 tweeter and 1 array.
    Counting the top MW as 1 and so on. When I get down to 3 it has a "white" wire attached to the black wires going back up to #2. That same white wire also goes to the white side "negative" on MW 2! Plus the main black wire coming from
    the XO is feeding the #2 MW and 1 MW. However I forget what is feeding 4 for right now. But am real sure about the rest.
    If I am correct in assuming this, I have something wierd going on?
    Or is this correct? Again, #3 has a black and white. but in that harness a (white wire) is laced into the black wire(s) on #3 going up to white side of #2. Black side of 2 (negative)is being fed by the XO black (negative).
    So does #2 have two positives now? how could this be?
    I checked both Right and Left speakers for reference to one another and they are BOTH wired the same way!
    Any suggestions from you hardcore polkies? Riccardo? Headrott?

    regards,
    Matt

    Hey guys,
    I fixed it. I reversed the screw up took. Can you believe I have been listening to just two MW's in each side all these years? Wow it really rocks now. However now my cd player skips due to the increased bass! Oh well. Sorry for so many posts.

    Since both are wired the same, that should tell you that the wiring is correct.

    Are you saying that you changed the wiring?

    Jesse,

    Im saying I had a momentary lapse of reason... I put the wiring back to its original state as close to as I could. The only change that is different in the
    original harness is now a break in the black wire. I twisted it back together
    and soldered them together (cardas) and shrink wrapped it.
    That was a very unwise decision on my part, but I had to tinker to learn that was NOT the right thing to do! LOL
    Thanks again for ALL your support. I STILL need to know about the spikes.
    Grant (mye sound) told me that the 1/4-20 will snap off.
    What would you do? :confused:

    i have NO bass from my 2.3TL's as well. i did the test and they seem to pass.

    Check your receivers' output settings and check large or small. You should have tremendous bass.

    He offers that thread pattern on one spike size only, so that's the one you should order.

    Hey Matt, I have the middle sized spikes from Grant (they are no longer available I believe) on my 1.2TLs and have had no problems at all with them and they are on top of a rug. Even when I walk them (you know the ole SDA dance) no problems.

    They only way I could see a problem with the 1/4-20s is if they are not completely screwed in.
