New member, long time SDA-1C owner

[Neo Fender]

As the subject states, I've owned a pair of walnut SDA-1Cs since new, serial # 11XXX. I believe they have the SL2000 tweeter but if I recall correctly subsequent polk speaker models came with an upgraded tweeter (SL2500 ???).

I understand there is an upgraded tweeter available. Is this a worthwhile upgrade from a cost/performance perspective? I'd also appreciate any other links or information on the entire, late great SDA line.

Welcome!
I understand the SL2500 may sound a little better. Others can probably help more though. The 1C is an awesome speaker!

2500 and then 3000 in the tl line...

neither is a drop in replacement for the 2000 as they required different cross-overs.

the current replacement for the 2000 is the 2000t, which a few folks have moved to and report smoother highs...

contact helen at polk cs to order them. as a club member you get a discount and free shipping... works out to $44.95 per as i recall. if you're in one of a few lucky states, you get to pay sales tax as well.

you may be able to sell your 2000's here...

welcome to the club...

I say if they work fine, why play with them. Wait until you need a new tweeter and then see about the upgrade. Man I wish my HT speakers sounded as good as the SRS's.

To the best of my knowledge the SDA1C always had the SL2000.

The crossovers would, as Tour mentioned, need different components to accomodate a different tweeter like the SL3000 or SL2500. The schematics for the 1C, don't show a modification redline.

I am going to go into the new series, 2000t, after a couple of my SL2000's burn up. I don't expect that to happen anytime soon, but the word is, that they sound better.

I misunderstood the question, Neo meant later models period...not just SDA1C.....ugh I am brain dead.

Sorry, but that comment still stands damnit! :D
