Peavey did two cabs, 1516 with a 15 amd two 8's, and an 1820 - leave you to work that one out. Long time ago mind but they still pop up and I saw a guy using a 1516 with an old MK 4 a few weeks ago.
The Peavey cabs had a crossover and I expect the Ashdown will as well, so the usual issues of mixing drivers wont apply. Trace did a cab with a 1x15 (I think) and 4x10 to go with the AH1000.
All of these are gonna be hard to find. The nearest equivalent are going to be Dr Bass or Alex Clabers cabs with a 15 and 6 inch midrage, or Accugrove if you got loads a money.
