@bondmanp Unbelievable coincidence. I just sent my primary away for significant upgrades and pulled out my 22k input impedance Adcom GFA-555 back-up amp. I have two 2wq subs. paired to my Treo CTs. I would suggest setting the crossover to 10k. That means you want switches 2,4,7 ON.
When I have my 100k main amp in system I have the crossover set to 75k. Integrates beautifully.
Please try 10k I really hope it works well for you!
