just picked up a mint pair of SDA1C's...however, trying to resolve some issues...

Check these things out. They are in fantastic shape. At this point, I have SDA 1B's, 1C's, and 2B's..haha..

I made a post a while back about the mids on my 1B's and unfortunately I'm running into the same issue with these. I thought it might be slightly different considering the different mid drivers, but nope. I just find that these speakers make piano's sound bad...they come out of the mix too much, but don't sound clear or defined. I notice it particularly on Diana Krall's "Look of Love" piano solo.

I love everything else about these speakers and I would like to try to alleviate this if I could, but before I go through the trouble and expense of recapping, I want to see if there's a way to remedy this or if anyone else has run into this. It might just be that I just don't love the sound of these speakers, who knows. I find that the SDA2B's aren't as harsh so I plan on recapping them anyways for the fun and experimentation of it. Is there any way i can smoothen out the mids of these speakers a bit?

before anyone asks, I've tried different preamp/amp/cable combinations. When I swap these out2g1iy6lqf1yr.jpg

for my JBL4425 or Kef 103.2's and play the same song, it sounds fine. With the SDA's, that piano is WAY out front, but not very clear. It actually hurts my ears..haha..

Lastly, one of the binding posts broke off...any recommendations as to what I should replace them with and where I should get them?

Thanks guys...

check these beauties out...

    Try getting them six inches or so off the back wall, and check to make sure they are wired correctly.

    First thing on the list would be to restore and upgrade your crossovers. This will go a long way towards increasing the performance of your speakers and your enjoyment of them.

    I do pull them away from the wall when I listen to them, I just put them back when I'm done so no one bumps into them when they walk through my living room. I also checked all the wiring and put those rdo194's in right away.

    I want to redo the crossovers, I'm just afraid I'm going to spend the 400-500 on boards and quality caps and still hate the mids, and then have the resale value be next to nothing. These don't sell well in my area. That's why I end up getting them so cheaply. They just sit on CL and Facebook Marketplace. Most people don't know what these speakers are.

    You won’t be selling them.

    Put all the money into the 2B's. Sell the rest.

    I plan on doing the TL mod with sonicaps to the 2b's first to see if it makes THAT much of a difference..if it does, I'm going to mod the 1C's as well to see how they sound. I"m selling the 1B's to my best friend for his new house. It's his first nice stereo set up.

    I'm saving up currently to do the 2b's and I'm trying to get this local guy to sell me his SDA2A's with the nice real wood cabinets. I just want to get the cabinets so I can swap all my 2B parts into them. I like the way the real wood cabinets look. I should be able to easily swap everything, correct?
  • oh...and for the 1C crossovers, do ya'll still recommend the sonicaps over clarity caps? or is the 1C a totally different animal. I know everyone seems to recommend the sonicaps over clarity caps for the 2B's.
  • pitdogg2pitdogg2 Posts: 14,291
    Sonicap tends to have exact values needed for most if not all SDA's. Nothing wrong with Clarity, values seem to be off a smidge one way or another or the need to parallel to get said value. Many do like them so it is more personal preference than anything.
  • F1nutF1nut Posts: 42,662
    The 1C's have a very different sound than the 2B's stock or modified.

  • I really just want speakers that sound as neutral/transparent as possible. I'm a professional musician..I like things to sound real and uncolored. I don't want to brighten them up or anything like that. It seems to me that sonicaps are the way to go for that, at least that's according to what i've read.

    does anyone know if I can just simply swap the components of an sda2b into sda2a cabinets? I'd like to know that before I try to buy his. I'm fairly certain his are A's because of the blade blade IC, and I want to stick with the B "guts" because of their modification capabilities.

    interesting...so the blade blade cable doesn't necessarily mean it has a dual board crossover?

    Why would you do that 2b cabinets shot? Cabinets cut out would be the same for drivers and tweeter. SDA2b are cheaper to buy caps for but you would need to pull driver to make sure one is A or B. SDA2a has both drivers MW6510. SDA2b has 1 MW6503 and 1 mw6511

    The 2B crossovers and harnesses will work perfectly in the 2A cabinets.

  • damn..that's quite an extensive list of mods. When I get back home from my tour, i'll mess around with the position of them a little bit and see if that helps. I just find that the mids can be overpowering at times, but it's usually only an issue with the SDA cable connected. I actually disconnected the lower SDA driver on both speakers as an experiment and it mellowed things out a little bit. I think the SDA effect just has a tendency to make the mids sound a little odd to me, but not using the SDA cable takes away that massive sound stage that I love.

    In summary, I think I'm just going to redo the crossovers on my 2b's with sonicaps first and see if the difference is substantial enough for me to want to do it to the 1c's as well. If I still don't fall in love with these speakers, I'm just going to save and get a pair of JBL L250's like I've always wanted.

    and thanks for answering this...My current 2b's are pretty mint in terms of the drivers and everything and there's a local guy with a pair of 2A's (I think they are 2A's due to the blade blade cable, but hopefully i'm wrong) with the real wood cabinets I want. I want to try to buy them cheaply and make one awesome pair of 2B's in the real wood cabinets. Just wanted to make sure everything would swap easily.

    The 2B came in a studio and regular version. The studio covering is a vinyl laminate available in black or wood tone colors. The regular 2B has wood veneer end caps with cloth side panels. The 2B studio cabinets and 2A cabinets look vertically identical, but the 2A could be had with wood veneer or wood tone vinyl laminate.

    So, what you think might be wood veneer is actually vinyl. Decorating tip, black goes with everything.

    i'm talking about these....these are all real wood, correct? and if they come in this variation, does that guarantee that it's a 2B as opposed to an A? In his pics, I see a blade blade connector so I just assumed that meant it was an A

    Yep, early 2B blade/blade with wood veneer end caps and cloth sides, which are falling off.
