Vandersteen 2Wq subwoofers with M5-HP crossovers - help needed

I have been happily using a pair of Vandy 2Wq subs with single-ended M5-HP crossovers for a few years now. My system was dialed in the way I like it (bass a bit on the full side, but still tight and defined). I just had my amplifier repaired and upgraded, and the new input impedance is 22k ohms vs. the 10k ohms before the upgrade. I followed the Vandersteen recommendation for the jumper settings in the M5-HP (6 and 7 only, "on" or not open), and the bass is just about MIA altogether. As per the Vandy web site, I disregarded the chart on the case of the M5-HP and followed the chart on the web site.  Because I am an idiot, I didn’t bother to mark down the settings of the jumpers prior to changing them. Anybody have any suggestions for me that will restore the bass? I am pretty sure the issue is the jumper settings. Thanks in advance!

@bailyhill great ! The new 3 is killer

the Apogee stage work quite well with the now discontinued model 2 sub, so you should have no issues :-) enjoy the music

@bailyhill,
Nice post. And, I agree that Johnny R is one of the best dealers, as well as the Vandy method of integration.
But, I think you should start a new thread. as this is more of a Sub 3 than M5 crossover issue.
I would be interested in hearing your Apogee's. I haven't been able to hear them, but know of their performance, and unfortunately, don't have the room to give them. But, hey, knowledge is power.😉

I, too, will be ordering the Sub 3's from Johnny in the, hopefully, near future. I also hope he will come to my home and set them up.

gdnrbob --I think that's a good idea to start a new thread.  I will do that after I get my "M3's" and tune them to my room and report the results.
