I'm very interested in seeing your graphs. I was going to point out the trouble that SPL meters have with lower frequencies but Gonk (as always) took care of that. The Radio Shack SPL meter is down 1 to 2 dB in the range of interest here so that's probably a non-issue.

I'm not sure if the 970 is the same animal wrt the analog crossover in the 6 CH direct. Regardless, I find it hard to believe that none of us noticed a 110 vs 80 Hz crossover when the 950 came out. We were all over this thing if you check the archives.

I'll be tied up for the next couple of days but I'll check in when I can.

Gonk, if there's one constant on the internet, it is you contributing to this forum. I'm glad to see you're still going strong.

Regards,

Bill
