I have a couple of questions....

Siddhartha

1. After at least 14 years of storage, I powered up my 10As and one of the tweeters did not work. Is it likely that I will have to, or should, replace any other components due to the speaker's age?

2. I heard a pair of SDAs back when they first came out and wanted them bad but I was a poor college student... There are two pair of SDA-1a on ebay right now and I am tempted.

What are the watch outs for these speakers? I read somewhere that they need robust amplification to properly drive them. Any recommendations for amps\receivers for these speakers?

Thanks

check to see if your monitor 10's have a fuse on the back of it.. if so.. it may just be a bad fuse. the fuse only protects the tweeter.

if yours do not have a fuse. then the tweeter may have come unplugged over time.. in which case remove the 4 screws on the tweeter and check the connections. if nothing is wrong.. then remove the tweeter and touch the red and black terminals on the tweeter to a speaker wire at low volume level.

Also hold out for the later SDA series. Like the 1C, or 2B over the 1A

I've got 1As that sound very good and plan to upgrade them at a later date by going to a single tweeter per cabinet and using the new replacement RDOs. (available from Polk at a discount to forum members) These same tweeters should work in your Monitors. IF you ship/transport SDAs or Monitors, make sure that the 6.5" drivers are removed beforehand and carefully packed/padded/boxed separately to prevent their being destroyed by jarring the magnets loose!! I paid approx. $265 for my 1As and have no regrets although I later found some SRSIIs which I like a lot more.
Good luck!!:)
