Welcome to the Pi forum. The Black Widows have similar T/S specs to some JBL speakers. I haven't used the 1808's but I have run 1505's before. They sound pretty good and if you end up keeping them they will be a good place to start. The 1505's had a good range and a clean sound, but I gave them up for JBL 2226's which have a little more punch and better dynamics.
