These are all good suggestions but my limitations are fairly significant when it comes to room placement. The configuration of the room, although furnishings have had a few changes, has been the same for 37 years. I'm a little reluctant to spend a lot of money on electronic fixes (passive or active) or new panels even though it may be advisable, because what may be necessary in the end is new speakers.
The first thing I'll try, then, because it's cheap is add a 4 ohm resister in series in the woofer wire. Here is how I plan to do it and where I need more input. I'll remove the jumper between the high and low frequency speaker connections and replace it with a resistor. This is where I need some advice and won't even try it until someone with pertinent experience reassures me that this won't cause further problems. It makes sense to me but could use some hand holding here.
