    If they are different it would be with the tweeters.Are they black on the TL's and silver or clear on the t's?

    What came in the t?
    You may need to upgrade the xover or you may just need to buy a 194 or 198.whichever it uses.

    I think brgman is right. The tweeters and xovers are different. I just purchased an xover upgrade for my old 8Ts and the manufacturer said that they would not work on 8TLs.

    There is also the "wing" on the front baffle of the TL's to reduce tweeter interaction.

    Every pair of "t"s I ever owned (seven pair) had beveled edges on the cabs. The TL did not.

    To convert an RTA 11T model to "TL" statis you would have to change one inductor from 0.4mH to 0.3mH, change one resistor from 2 ohm to 1.5 ohm, change one cap from 12uF to 16uF, remove the poly switch, remove a 2.7 ohm resistor and change the tweeter. Not impossible, but probably not worth the cost.

    You are correct, http://www.polkaudio.com/forums/showthread.php?t=121660

    $15.00 plus new tweeters = no brainer.

    It's not worth the upgrade, keep them stock and upgrade them normally.

    Besides the use of the SL2500 tweeter vs SL-2000, the RTA8TL utilizes the MW-6516 mid-woofer vs the MW-6501 in the RTA8T. It also has improvements to cabinet bracing. The port has also been re-tuned and repositioned. They also added leveling feet and floor spikes.


    I'd be reluctant to try to make the RTA8T into an RTA8TL. Swap the tweeter with for the RDO and upgrade the XO caps and resistors and you will be very pleased.

    Ya i seen those but the sticker in the pic says 11t not tl. Will those work if i just swapped out the xo's in my 11t's and then i could get some RDO's to replace the sl2000's?

    There's only one resistor and no poly switch meaning they are 11 TL crossovers.

    Ok so I could buy them and replace them with the original xo's. Will they work for now with my sl2000's until I buy the rdo's?

    Not very well, but you won't damage anything. Probably won't sound all that great, but depending on how picky you are, you could probably get by until you have the $$$ for RD0's.

    Or buy the x-overs and hold onto them until you get the RD0's and install at the same time. Unless your stock x-overs are shot.

    My take on it......will they work in the sense that the crossover will pass a signal to the tweeter and drivers? Yes. Is it something you'll want to listen to? Hell no.

    Excellent idea, Brock.

    Thanks for the verification.



    DJ,

    I also have the SL2500 tweeters (or SL3000 tweeters if you feel like going that route) available as well. AND the tweeter flaps...
