Do *all* vintage Polks benefit from replacing the tweeters, or just some of the models?
The two pairs I listen to regularly are SDA SRS 1.2 (non-TL) and SDA 1C.
But then I also have a bunch in storage that I occasionally bring out:
Monitor 10 Series 2
I assume some of the models use the same tweeter replacement?
Obviously I cannot afford to replace all the tweeters in all the speakers (heck, just replacing the tweets in the 1.2s won't be cheap), but which models would benefit the most from the upgrade?
