As said earlier in thread the woofer surrounds are a weak point because they're made of foam which breaks after 20 years.I have repaired mine with a thin rubber surround and this works very well.Do not use the thicker rubber,the suspension will be too stiff.
The overall response can be improved with an amp that is able to control the bass well.Otherwise it will sound too thick and too slow.I (still) use a Levinson 23 amp which works well.
Further,the internal cables that were standard in the speakers are (by far)not good enough.I have changed mine (about 10 years ago)for vanden Hul SCS cables.The improvement is big,but change the cable to the bass unit too or it will sound slightly discontinous..not as much as the Martin Logan Sequel though.
You could buy even better cables nowadays (Cardas,MIT,etc)
And then there is the crossover,it consists of many capacitors of inferior quality.You could cange these for better ones (i used Chateauroux,but there are more good ones)
