I got them!

Well I finally acquired some 2.3TL's yesterday and moving some stuff out of the way to position them better. I wasn't 100% positive they were the TL's since they weren't stamped "TL" on the back plate, but I am 99% re-assured after my other post that they are the real deal. I also ended up getting an Acoustat TNT200 amp(all mosfets). I knew that would be a good amp for them as I have had a few of them before, driving big Infinities. Those amps also have a damping factor of 1000!. I am sure glad I held out waiting for a set of TL's instead of jumping on the 1st set of any big Polks. I will take a few pics after I get them in a better position. They sound good now, but I know I can get them even better. :eek:

Congrats!
I don't know anything about that amp but just make sure its common ground -

Congrats! The easist way to determine if a set of 2.3's are TL's or not is to look at the drivers. If the top and bottom drivers (on the side with 4) are donuts, they are the non-TL version. If they are real drivers, then they are TL's.

No donuts
. I am already looking into possible upgrades(it's my nature). Should I just keep the sl3000's in there or are the rdo-98's that much better? I am also going to spike the bottoms to see if that does anything. What is the single screw on the back for? It is between the label and the binding posts? It is loose and won't tighten. Anything else to tweek? Jeff -
Congrats! I suggest listening to them for several weeks to familiarize yourself with their sound, and then start the mods

I don't want to modify or alter them, just simple improvements for now.Jeff

Actually it's really easy to tell the difference between the 2.3 & 2.3TL's as you cant always go by the color of the tweeters (they may have the RDO-194's which look just like the SL-3000/RD0-198's) and whether or not they have they have the doughnut drivers.No donuts .

Take the grill off the left speaker (look on the back label to make sure it's the left one) looking at the front on the 2.3's going from left to right you'll have 4 6 1/2" drivers then 3 tweeters then 2 6 1/2" drivers, On the 2.3TL's this will be reversed.
On the SL-3000 vs the RDO-198 most will say the RDO's sound smother/better less harsh. I've never heard ether one so I can't really say. But I'd guess most here will say get the RDO-198's and upgrade the crossovers.
On that bolt I believe it's what hold's the crossover in place. You'll have to pull the passive then remove the crossover board from that big round inductor after which you'll find a nut covered in hot glue that you'll need to get hold of in order to tighten that screw up. Just pick out all the old hot glue then tighten it up the cover it back up with new hot glue.

I had SL-3000's in my 2.3TL's when I brought them home 5 months ago. I listened to them for a couple of weeks, ordered the RD-0198's and swapped 'em in. H-U-G-E difference, for the better.
The new tweeters are smoother with no roll off of high frequencies. Better imaging too.
With the first song I played any doubts I had about whether or not this would be an upgrade or a lateral move (not better, just different) vanished.

Welcome to the SDA. I would recommend some type of tape on your face cheeks to prevent that permagrin that SDA owners get.

If that screw is loose it needs to be fixed as you will have an air leak. That screw is for what they call a bass brace to fix the speakers to the wall with a piece of all thread, I made my own and mounted them most don't use it as its not needed but I do like that my speakers feel solid and don't move. It does help with the the bass a little but putting spikes on them will give you greater improvements in bass and clarity. But do fix the screw so you have no air leaks..Polk Audio SDA 2.3tl Fully Hot Rodded. 😎

Also if it will not tighten then the t-nut is not seating correctly on the inside of the cabinet, if it will not seat and you have no plans on using a bass brace then just put some hot glue on the inside over the t-nut to keep it air tight..

Thanks, I will look at it in the am. I take it I have to take out the PR. I am trying to get them to image better right now. Not getting a crazy drum roll from right to left on certain tracks that I am used to. I should upgrade my Beta 40 preamp eventually.Jeff

Did you buy these in the Seattle area? I saw some 2.3s for sale locally and I was very tempted to "trade in" my 1Cs. Good snag!

Larry if I'm not mistaken isn't the bass brace bolt higher up more to the top than between binding post plate and label.“The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain -
I can see where the brace would go towards the top. These are way down by the binding posts and are a black phillips head, not a tee nut.Jeff

Yep That's the one that hold the crossover in place. Actually I think it's an alien head bolt See my earlier post #10I can see where the brace would go towards the top.

Yep I read it wrong the bolt your talking about is for the crossover...

Quick question. Should I check the wiring in the 6510's? I pulled one out to have a peek. The black wire is going to a red dot, which looks to be a hand painted dot, not a label. Just wondering if maybe their might be a phase issue?Jeff

I knew that would be a good amp for them as I have had a few of them before, driving big Infinities. Those amps also have a damping factor of 1000!.
The damping factor has a lot less to nothing to do with how good an amp is. Here's a good read on the subject, http://www.audioholics.com/education/amplifier-technology/damping-factor-effects-on-system-response

Black or blue is positive. White or green is negative. The black wire should be connected to the red dot terminal.Political Correctness'.........defined
