SDA2B, how do they compare to the SRS 3.1TL

I currently have a pair of very nice SDA2Bs that I picked up from an elderly couple who bought them new in the 80's. They have hardly been used and look brand new, I absolutely love the sound that these speakers produce.

I found a pair of SRS 3.1TL with upgraded 198 tweeters, new binding plates and posts. They are almost double what I paid for the 2Bs and wonder if my setup could benefit from the SRS speakers

    Or use that money to upgrade your 2B's. The 2BTL's are very good speakers.

    I love my 2B's and my wife does too, I definitely want to upgrade my 2B's but the 3.1TLs I found are going to cost me the same if I upgraded the 2B's, in the long run won't the 3.1TLs be a better speaker than the 2BTL.

    I wish I could listen to the 3.1TLs with my setup in the same to make that comparison. I guess worse case scenario I could flip the 3.1TLs if I don't like them and put the money back to upgrading the 2B no harm no foul, right

    I have had the SDA 2B since I bought them new in '91 or '92. I did the TL mod on them 2 years ago. I don't have the 3.1TL but have had (unmodded) SRS 1.2L for about a month.

    The 3.1TL is a nicer speaker than stock 2B. The TL mod brings the 2B very close it's bigger brothers sound wise. I moved the 2BTL into my home office and I they are just so incredibly good I often wonder why I got the 1.2TL. The big ones should however handle my living room better. I just need to supply more power to them. The 150wpc power amp was great for the 2Bs but a little wimpy for the 1.2TL.

    I'd keep both. Spend a little doing the TL mod on your SDA 2B. It's inexpensive and will transform your speakers. The RD0-198 tweeter is great (and inexpensive) but you can save a little if you find used SL3000 and not sacrifice much. I've trued swapping the 198 and SL3000 back and forth and simply can't hear any difference. Booth are much better than the original SL2000.

    I'm sorry but have your hearing checked @hauxon.

    I'll could not go back to the sl3000's if someone paid my 5x what the RD-0198 costs. In my 2.3tl's it was an oh my god why did I wait so long moment to get all new tweeters. The sl3000 is leaps better than the sl2000 but the RD-0198 is leaps better than the sl3000 no question.

    If you can't hear how much better the RD0198 is, something is seriously wrong.

  • You don’t say what double $ is.

    When I was looking not that long ago the wood cap 2Bs were 2-4 hundred. The 3.1s in my area were 6 - 8 hundred. I had an offer for 3.1 with 198 swap for 6 hundred. Before I got them bought they sold on eBay for $800

    2Bs are about 80# each. The 3.1s about 100# each

    I ended up getting some 3.1 and I am going to keep and modify. I had 2B in the past but not at the same time. The 3.1 seem more rounded to me.

    I would get the 3.1 and try them if you can. Sell the ones you don’t prefer.

    Haha, you guy's are great. I'm just saying there there is an easy to hear difference when you take out the SL2000 and put in the RD0-198 after the TL mod. The 5db peak around 12Hz is gone and S and T sounds become more natural, it just sounds much smoother. Very easy to hear.

    However difference between the SL3000 and the RD0-198 are much more subtle. Both are good tweeters and the newer 198 a notch better, but by a much smaller margin than when compared to the SL2000. There would be nothing horribly wrong with using the SL3000 in your SDA 2Bs. You could even use the $100 saved to buy Gimpod boards or better caps. You will need to do the recapping soon anyway. If there are no budget restraints the 198 is the obvious choice. :)

    I bought mint studio 2B's for $300 and these 3.1s are $600

    The 3.1TLs with new tweeters are a bargain if they are in good cosmetic shape in addition to the updates. The 2Bs were priced a little bit high for a studio version. Still one of my favorites though if the tweeters are replaced.

    Who's binding posts and plates are installed on these 3.1TL's?
    $600 is a great deal you can count on a $200-$300 gain if you just flip them.

    well damn I didn't even catch that, it said interconnect cable included but I didn't even see that it was completely missing the socket, very interesting

    Perhaps they wired the biamp into a single set and the other set is for SDA interconnect.

    kind of what I was thinking as well. I would have at least marked which is which with a label maker of some sort that is just asking for trouble imo

    From the seller, "It was rewired when the post and plate were installed. They cant be bi amped. The to connections are for the interconnect"

    I would never of worried about bi-wiring them. I would have used a much different approach to the socket though. Seller took the easy way out. Proper rewire would have been speakon like these in the link. MUCH better option and was less chance of a mistake.

    Now the link is just for reference as not all of these connectors are air tight which is extremely for a seal speaker design like SDA's

    these below would be correct I believe

    Those binding post plate cap screws are seriously rusted. That much corrosion should give one pause.

    Yea I noticed that too, that area they are in an area that flooded recently so it's possible that those speakers saw some water. I think I'll pass on them as there are too many questions and they are a few hours from me. I'll just upgrade my 2B's and be a happy camper
