Just wanted to share a story and a thank you.
Long story short- For years no room for my 2.3s so the bad poly switches were a moot point. I considered selling them.
I now have room.A few weeks back on a Wed., I e-mailed Ken Swauger for parts and that Sat. found poly switches in the mail.
The new switches are in, the highs are back and ......YEEEESSSS!!! I remember why in 1989 I bought speakers I really couldn't afford.
Classified- Polk SRS SDA 2.3.......NOT! for sale!!! ( :
Take care all
