[LAU] Amp / speaker combo for Piano

[Gerhard Zintel]

Hi,

I'm looking for a amp / speaker combination for keyboard. It should be 
especially give good reproduction of piano sounds (using Pianoteq) and having a 
solid bass floor. I have to fight 4 (non amplified) wind instruments (B.CL, 
2xTb and Alto Sax) and a drum kit in our rehearsal room.

For I have to substitute partly a bass player it must be able to reproduce the 
sound of the lower keys sufficiently. Price below 1000 € and and not too much 
weight would be benefits. 

I'm grateful for any hint.
Gerhard
