Load IIR Coefficients from REW

Question

Hi, 
 
 I'm totally new to using SigmaStudio, trying to build a speaker crossover with the ADAU1452. 
 
 I've added some 2nd-order 'General EQ' filters and tried to load coefficiants generated in REW (Room EQ Wizard). However it seems to be unstable and output no sound.

Can anyone help me understand what I need to do to get this working? 
 If I need to convert the format, what do I need to do? 
 Thanks!

Sorted, all I had to do was invert the signs on a1 and a2.)
