    Buy some leviton or Hubble hospital grade outlets from your hardware store, they cost around 15-20 bucks, and will get Your toes wet. They have nice grip, my old plugs wouldn't hold the cords and would start to unplug.

    I've been curious in trying some furutech FPX gold plates outlets. They are around 90 bucks a piece. I love the furutech quality.

    I used hospital grade outlets with my dedicated circuits. I was sharing my work with Mojo Audio's owner. He complemented my work but said it would be better not to use hospital grade because their plating does not yield the best sound. He recommended Furutec copper as a great choice. I plan to swap out a couple of critical outlets in the near future.
  • Re: Driver/Speaker rings for your vintage Polk SDA's Monitors..

    Welcome to the forum!

    Here is a link to a thread rebuilding 2.3TL's.
  • Re: Is there such a thing as too much black hole five?

    I removed the BH5 from behind the tweeters and cut 5" off each end of the strip behind the sda drivers. So now it is only behind the mid stereo and sda drivers. Turns out this is 42% of the original BH5 area. Not a trivial amount.

    The overall balance is better along with the stronger bass.
    A little bit goes a long way. Live and learn.

    I bought 2.3TL's a year ago. I found my notes about listening in stock form:

    I did some more listening last night. In their stock form I find them sluggish, muffled and veiled. They have nice mids and vocals sound good. Top and bottom end is not extended. I am writing these notes so I can come back to them as the rebuild progresses.
    My hope is that this rebuild will transform these speakers just like my last SDA-1A rebuild.

    Just changing tweeters to RDO198's made a huge difference. Here are some notes about that:

    I swapped the tweeters to RD0198s. Right out of the box they kill the SL3000s. I did not realize how much of an impact they would have on sluggish bass. I will keep the radio on for the next day to start the burn-in process.

    I have continued the upgrades and can say that they have been transformed. I live near Hilton Head Island, SC. If you are close you are welcome to visit and listen.

    2.3TL's not the same as yours but some of the supports were close to the tweeter rings and needed some tweaking.

Howdy, Stranger!
