    i've been seeing this thing about the crossover mod.. what is this? what does it do? how hard/expensive is this to do? how?
     
  2. A crossover like the one in an Avatar cab controls which frequencies the horn will play. There are different levels of how much frequency cutoff there will be between different crossover types. I picked up all the peices for a 4th order linkwitz-riley crossover for $22.81, and I plan to build and install it when my new B212 cab shows up next week. There are a few pictures of what the crossovers looks like, but I'll take pictures of the process of building and installing one incase anyone is interested. I ended up spending about $370 total on this Avatar 212 with ernieball pop-out casters and a new crossover. Most comparable 212's come in between $50-$250 more, so avatar is a good deal.

  5. If you build your own here are some suggestions:

    May I offer some suggestions on your building of the crossover for Avatar's Tweeter of things I have found?

    A. On the boards run the grounds to a single point
    B. Run one ground wire from the ground on the tweeter control to that ground point.
    C. Use emerycloth or fine sandpaper to remove the insulation from the coils for soldering.
    D. If you are going to keep the 1/4" inch Jacks in place for use the isolate them from the Control Plate for less hiss. I just clipped the wires from these on mine as I use only the speakon connector. It appears since the Tweeter is realitively efficient, grounding the Control Plate via the 1/4" Jacks can make the plate like an antenna of which the tweeter will pickup unwanted noise.
    My unit on my amp is very quiet now.
