Thinking of getting SDA 1C's..

I'm new here.
I'm really considering maybe picking up some 1C's fourth gens.

I had a few question's. How hard are some of the mods for a rookie. I haven't even ever placed a tweeter. I would like to at least replace them with the upgrades. Been looking around for a good guide.

Or if By one knows of any fellow pokies near Toronto. I'm in Orangeville, Ontario. I would rather pay someone experienced to do some mods if possible.

    Your ears will thank you.
  • I pulled the trigger on the 1c's.
    I did the light poke of the woffers to see if all the drivers move and they do.

    They sound wonderfull, but I feel like I'm not getting the depth I expected. I was hoping for airy and depth.

    I read on the forums to unplug one speaker at a time with the interconnect left on and the cable seems to be drive the other speaker with the interconect still attached.

    I have them set up as suggested in the manual. I have a dresser in between but have pulled them out and in as suggested also.

    The speakers are also 100% original no upgrades.

    Any suggestions?

    Congrats on the purchase. Wish I still had my 1C's.

    What are you using for the rest of your rig? Amp etc.
  • I'm using a Icon audio 20pp tube amp, schiit Modi 2 Uber multi bit dac and go on or hqplayer. My amp I feel powers them really good for the low rating.

    With a 100wpc or more should I get more depth and a airy soundstage and image?

    Yes to some degree, but those traits come from more than just the amplifier. Everything in your system contributes to....or takes away from....those things.

    I went from a 50 watt / channel tube amp to a 100 watt / channel to power my 1c's. Huge difference. They really opened up with the increased power.
