I noticed exactly what you did... above 50hz seems set the clip lights off. I don't have an external eq so I can't really faltten out my reponse a whole lot but I did have a peak at 60-65hz so I knocked that down with my avr and I get quite a bit of output at all freq before the lights start coming on.
Yeah, that sounds about right. I haven't heard them for a week or so, but before I ripped them apart they were loosening up. The higher frequency clipping was still achievable but at higher SPL, and by the time any low frequency clipping occurred your clothes were moving and 10lbs lamps were thrown off the tables upstairs. My roommate ran down stairs screaming, "Everything's is falling down!".
The upgrade to 240V at 20amps should do. The Crown is doing what its spreadsheet claims as it snaps a 20amp breaker in a heartbeat. What's unknown is whether the clipping will lessen when it has its recommended mains, which will be nearly double what it has now. Sounds like the Crown runs best on 240V, as well.
An impedance measurement will be taken in a couple weeks and the LF personality modules in the crossover will be changed. That coupled with the amp having its recommended mains and the woofers being worn in should make a noticeable difference.
Like you a LG clone or even a real one would be nice, but that will just have to wait.
