Martin Logan Quest Z speakers: balancing the woofer? Suggestions?

Speaker Asylum

General speaker questions for audio and home theater.

I was thrilled to find a pair of used electrostats ( Martin Logan Quest Z speakers ca. 1993) I could afford and brought them home with great anticipation. However, when I set them up (jumpers between the two speaker terminals) with one amplifier, though the treble was great, the bass was so subdued as to be practically not there at all. (My amps are Cary 70 watt per channel monoblocks)
So I hooked up my Dynaco ST-70 to the woofer leads and biamplified. Now the bass was heavy, tubby, chesty, extremely obtrusive and unbalanced. It sounded like a cheap subwoofer. I couldn't stand it.
My dealer suggested the problem might be fixed by using a solid state amp which has a volume control and carefully balancing the degree of bass until it blends smoothly with the treble panels.
Has anyone ever tried this? Is it likely to work?
The dealer will allow me to return the speakers for full refund and I can go back to my Audio Physic Sparks which are an extremely well balanced speaker. They do nothing gloriously, but everything well.
