  • Reverse the male-female terminals on the two wires to each driver, so they can't be connected in reverse polarity. Decide which way the + wires will be, do the - wires opposite. Or use 2-wire Weatherpack connectors which can't be connected backw…

  • Sounds like a 1B/1C cabinet. A true SDA 1 can be converted to a 1A. Polk once provided a kit and instructions. I thought the result of that was the SDA 1 Signature.

  • The split "round" boards and the single rectangular board on SDA 1Cs have the same circuitry, same component values...in different form factors. NO functional difference as long as both contacts on the SDA socket are connected. Polk did not connec…

  • ANY film cap is going to be better than the electrolytics they replace. Even the stock Mylar HF capacitor is bettered by "cheap" modern film caps. My SDAs have a combination of Dayton 1%, Dayton 5%, and ERSE 3% caps.
  • I suspect that someone with a conscience added the barrier strip...and printed a label to match. Perhaps a professional repair shop, after the supply of sockets dried up. A-L-L SDA 1Cs can use an isolation transformer (AI-1 or Dreadnought)…

  • Those crossovers would be easy. You could install FRESH electrolytic caps and be "as good as new", and it would cost almost nothing. If you do that, retain the silver-mica cap. I put Dayton and ERSE film caps in my 1Bs. No silver-mica required.

  • ...which is why it's too bad that speakers aren't trending toward 16 or 32 ohm, instead of 2-3-4 ohm impedance. Low-current, high-voltage amplifiers would be inexpensive. Current costs money, voltage is practically free.

  • Gauge size means nothing, but resistance does, and as a rule, larger gauge = lower resistance. Capacitor leads are not fifteen feet long, and the capacitor doesn't transmit the full amperage of the signal like the speaker cable does.

  • I'd call a little extra HF a gift from God--at least with my speakers. When I ripped out the polyswitches from my 1Bs, I did not install a resistor, just a jumper--and the top end could use just a bit more volume. With the polyswitch, the HF wa…
  • Tweeter protection fuses--are they fast-blow or slow-blow? Whichever they are, you'd want the same style in addition to the same amperage/voltage ratings.
  • I don't know about a difference in sound between foil and wire. The foil inductors sure look pretty, though. When I was looking at foil inductors, none of them had fine enough foil for my purposes--I needed 18 or 20 AWG equivalent. Although bot…

  • I think Yamaha used to be better than they are now. I've never owned a Yamaha amp or receiver. If I was going to, it'd be an older one. And I'd be REALLY CAREFUL about verifying the 4-ohm specs. They can still build a competent amp...but you'd…
  • Buy two RD0-198s, replace the main (primary) tweeter in each cabinet.
  • Again, that does not cancel notifications for INDIVIDUAL THREADS, a failure of Vanilla.
  • I am still hopeful for a way to UN-subscribe to individual threads, so I don't continue to get "update" notices via e-mail for threads that have gone bat-spit-crazy. http://forum.polkaudio.com/discussion/169226/unsubscribe-notifications#latest

  • I would be looking at IC Pin #2 to Red first. Corroded connection? Frayed wire? Fix it and re-test. What happened to Swauger's comment? Seems to be M-I-A.
  • Like EVERY seller of SDA-SRS 2s, you have to beg them to tell you if they're blade-blade or pin-blade, 'cause they don't have enough sense to properly describe them in the advertisement. As said, they're all over-priced especially the 1A.
