Sometimes I use an old-style ('87) 400RB head with an SWR Goliath Jr. III 2x10 cabinet. It's a pretty good setup for DB but by no means the best ever. I am using a New Standard Cleveland laminated bass with Realist and K&K Bass Max pickups. The GK head has a very quick response and is not too boomy or electric-sounding.
However I find myself wanting more versatile EQ for dialing out honky frequencies and adding definition. I also think that I'd prefer one or two 1x10 or 1x12 cabinets to the 2x10 for the sake of portabilty.
I recently had the opportunity to hear an Italian-made SR brand 150 watt 1x10 + horn combo. I know that the SR company is associated with Schertler; the SR I saw looked very similar to the Schertler powered speakers. It sounded great and had a really deep response for such a small unit. One or two of those with the right preamp could work very well.
It's probably a good idea to buy European. I buy mostly American stuff for cost and ease of repair. You should have plenty to choose from with manufacturers like Hevos (Dutch), Tech, Ashdown, MarkBass, EBS, and Glockenlang over there.
