I owned a pair of Watkins WE-1's for 18 years and then upgraded them to the WE-1A after buying the parts and schematic from Mr. Watkins for two more years. They never let me down and I finally had to sell them when I moved to PR for several years for my job (they would not have survived the trip by boat in a container to PR). I really did not notice a big change in the bass when I upgraded. the Tweeter range was extended down to 1500hz from 2500hz and the mid's were cut off a 100hz instead of running full range. The 40hz crossover to the sub was removed and all three 8" drivers covered the same frequency.
The other issue I had was replacing the bexetrene 5" mid's when their surrounds rotted out after many years. I will advise you that you need a "BIG" room for them to sound their best. I had them in a 16'x13'x8' room for many years about 4' from the rear wall and 3' from the side wall and they imaged deasantly. However, I will never forget when I had to move them to the garage while my wife got the carpets cleaned. I set them an played them there and and the bass almost knocked the garage door openers off the ceiling. They will play incredibaly loud without strain so watch your ears and keep them away from teenagers trying to impress their friends. They also need a LOT OF POWER since they are acoutstic suspension type speakers--no ports to boost the sounds--so give them about 200watts a side-8ohms but they are more like 4 ohm speakers. I saw a pair on audiogon and I might buy them just for the nostalgia and do the WE-1A upgrade. Good luck, dave
