3.1TL crossover question

Options
After looking for quite awhile I was able to acquire a set of 3.1TLs last weekend. They will replace my SDA 2BTLs currently in use. Apartment living limits how large I can go. I took a 7 hour drive of faith from Akron to Rockford IL to get them. The craigslist photo (1) was poor quality and the seller wasn’t anxious to provide additional. Aside from a water stain on one cap they are in great shape. I was happy to find RDO198 tweeters but nothing else had been upgraded. So the new journey begins.

My question is in regards to the undocumented 2 ohm resistor that is present on this set. I have seen other threads about it but did not find consensus on what to do with it. There are suggestions to remove it or replace it with 2 - 4 ohm or 3 - 6 ohm in parallel. I would appreciate hearing what others have done & the results.

    Fair point. The 2Bs will be taking up residence at my girlfriends. They’re not leaving the fold.

    Congratulations on the new addition.
    Seams like the 3.1's are harder to find. I had to drive over 9 hrs (SoCal to Phoenix Az & back)round trip to pickup the set I bought.

    Now it's a work in progress to make them sound/look the way I want them too.

    Leave it. Most sand cast resistors I see are 10% and 5 watt which suck sound wise. Your biggest improvement is going to be replacing the caps anyways. But WTF do I know...

    It was recommended to me to replace it with two parallel 4ohm 12 watt mills so that we get the 2 ohms and 24 watts of handling. I was told that the reason it is needed with this version is to compensate for the inductor they were using with lower gauge windings... I vote you try it both ways, and report the results.
