Cornwall iv

The cornwall IVs, you will not go wrong with them. They are  outstanding sounding speakers. They are large and heavy but beautiful . They have that 70s 80s look to them because of their size. They sound the best, I feel when playing live music. Any music of good quality recording will be exceptional. And whatever improvements you make to your system only makes them better. I found that damping the tweeters and mid horns with Damping tape easy to do and removeable improves the sound 2 fold . And my Mac amp is 450 watts so power makes no difference. Soundstage is huge.  Hope this helps

Thumbs up on the damping.  

Jeffseight, I don't think GR  Research offer a crossover upgrade for the CW4s, only the Forte 3s from the Heritage line.  If he does offer it, it's not on his sight that I can see.

For those using solid state amps, the Western Electric or Deulund DCA tinned- copper speaker cable works well with these speakers, helps take away the hardness or smooths things out a bit.  Either 12GA or 16.  12GA is going to probably be richer/warmer.  

Mine came with all the damping done and also lined with NoRez. Binding posts also upgraded. 

Well they have opened up substantially over the past few days. They are in the basement so I can leave them playing 24/7 at a pretty good volume. They have substantially more bass now than when I got them. Leads me to believe they were not fully broken in. Snare has more snap and more articulate mid bass as well. Really liking these so far. 
Running Room Perfect on the Lyngdorf is still giving poor results. These and 1 other speaker I’ve had issues with it normally makes a huge difference for the better. Just sucks the life out of them, I don’t get it. Really with the directionality of the horns I’m not feeling like it necessarily needs any dsp. With that being the case I may start looking at a nice tube integrated. Any suggestions on some good ones to start looking at would be appreciated. So far in my list is Octave and Ayon. 

Also going to email Lyngdorf and see if they have any comments on why the crappy results
