I used an 1810 for awhile back in the mid 80's. It was at a club I played regularly, and I always looked forward to using that cab. I thought it sounded great. Never had to move the 1810, but I owned and used most of the other refrigerator-size cabinets of the 70's and 80's, so it wouldn't have been a big deal.
If you're looking for a very modern bass sound and light weight and compact, these cabs may not be for you. Sonically they have lots of character, which is definitely old school. Moving is probably not really that bad... just my opinion though.
Keep in mind that these cabs and others from the same era were made when 2 or 3 hundred watts was a phenomenal amount of power and even 100 watts was a lot, so speaker cabs had to be pretty efficient to get the most out the power available.
