The Black Widow speaker really made those combos (and the cabs) sound a lot better. I never had a problem with any Peavey product from the 80's and 90's, but will admit that some of their components were more impressive than others.
The BW speakers were one of those components.
FWIW, all my Peavey bass gear is long gone - but still working to the best of my knowledge. However, I still have some powered mixers and teo Scorpion equipped 112 PA cabs from the early 80's which sound as good as the day I bought them at Chuck Levin's Washington Music Center. I also have two sets of mini-monitors (long ago discontinued) that are great for acoustic coffee house type stuff.
