New Internal Wiring for 3.1TL's

After enjoying the results of a rewire in the 2.3TL's, I decided to give the 3.1's the same treatment. I used 13 ga. Supra Rondo.

I went against Polks original color choice and instead utilized 'Mike Color Choices' :) Red for Positive, Black for Negative. Ordered a few feet extra and made up some Jumpers as well.

Putting them all back together and going to let the new wire 'settle in' for a bit before giving them a proper listen.

    Nice Mike! I did the same when I rewired my 2.3tl's with DH Labs 14ga. Silver plated OCC copper. Red + Black-

    Likewise. Have upgraded multiple sets of speakers but the one thing I've never done is internal wire and would be the finishing touch on my 1.2tl's (owned since 2010'ish). I also have a new to me pair of 3.1tl's that I just worked over the XO's, dynamat, BH5, etc. and am waiting on the last 2 inductors that were backordered. Mike, what was the total length of wire for the 3.1's?

    I can tell you now, it's a worthwhile improvement. The Stock Wire is around thirty years old, I believe it needs to be refreshed along with the x-overs, and Binding Posts, etc.

    Yes, Your Thread, machones, and others that have upgraded Internal Wiring prompted me to perform this on my 2.3TL's. The difference is quite notable, the 3.1's are liking the fresh wire as well.

    For the 3.1TL's I purchased 34' total of Supra Rondo 2x25mm from Madisound, this gave me 68' of total wire. But, I ordered about 4' extra to make up some jumpers as well. So, just for the speakers around 30' should do it.

    I'm not positively for sure, but I think Polk originally used a higher caliber wire in the 1.2TL's. Some Cardas, maybe?

    I'm sure someone knows for a fact.

    Yea They (1.2) were different but to my eyes it just looked like some standard clear jacketed rope lay wire. I do not think they were Cardas as that would have required extra work since most Cardas I'm aware of has enamel coating on all the strands that would require removal or a solder pot. The quick connects would not crimp very well to that soldered end.

    Yes I'd like to know as well as I have not seen the chassis wire for them up close and personal.

    Appreciate the lengths! First I've seen mention of Cardas as OE. I believe, sans searching, DK upgraded to Cardas? Kind of recall him using a soldering pot and/or scraping individual wires? In any case, my binding posts are Cardas. Glad to see you both experience positive results with the DH Labs and Supra Rondo. Have inquired re. wire a while ago and now am motivated to readdress and get me read on. Thanks, gents.

    ....edit to add: Found it, DK upgraded to Cardas Litz back in 2013. As per a DK production, detailed and informative. ;)https://forum.polkaudio.com/discussion/139282/cardas-internal-wire-replacement-for-the-sda-srs-1-2tl/p1

    Polk never used Cardas wire. The stuff in the SDA SRS is clear jacketed copper of an unknown source.

  • @Mike Reeter Very nice work indeed. I see that Supra Cables claims that the tin plating over the 5N OFC Copper (nice) reduces the chances of electrons making the strand to strand jump......hmmm.

    Is this the stuff you used.......Supra RONDO 2x2.5mm Speaker Wire per foot (13 AWG).
    I already ordered Neotech OCC 12 ga for my midbass driver, 15.5 ga. Cardas Litz for the tweeter circuits, and 11.5 ga. Cardas Litz for the binding post to crossover and enough of that to make a swapout for the Neotech to see which sounds better, for re-wiring my 7Bs which is much less of a hard job than what you had:

    Yes, this is the wire that I used for both the 2.3TL's and the 3.1's. It is very easy to work with and has a 'smooth' sonic signature to it. I used the same wire throughout, including Jumpers.

    Trey "VR3" has used this wire for quite some time I believe, I think Larry "Toolfan" has used this wire as well in his Supreme 1.2TL's as well.

    I figured if these guys were happy with it, it would work for me. And, it certainly does.

    A little less expensive here https://www.ebay.com/itm/SUPRA-Rondo-4x2-5-by-the-meter-for-DIY-BI-WIRE-or-BI-AMP-What-HiFi-BEST-BUY/151370352553?hash=item233e6047a9:g:~~wAAMXQxKxR84BL plus you get some White/Light Grey also.

    The rondo series is fantastic for internal wiring. Easy to work with, flexible, won't oxidize, sounds great, easy to solder, can't beat it

  • Mike ReeterMike Reeter Posts: 3,864
    I can't help you out as I've never tried the Classic wire. VR3 might chime in, I'm sure he has experience with both.

    Or, you might just give Madisound a call. They answer the phone and are very helpful.

    Mike, do you remember the total length for the 2.3TL's? I am going to do the internal wiring for mine, and thought you may remember the total length for the 2.3TL's, since you have done yours. I have used the Supra cable in the past to make an interconnect cable for my 2B's, so I know somewhat what it sounds like.

    Great job on the 3.1TL re-wiring! I may redo mine one day, but wil definitely start with my 2.3TL's.

    Thanks for your help Mike.

    I don't remember for sure, I'll have to search for an Invoice or Payment and see what I can come up with.

    pitgogg2 and machine have both rewired their 2.3TL's also, maybe one of them might remember and chime in.

    It takes more wire than you would think.
