Audio quality of speaker and TFA9879

We are using a TFA9879 with a CUI CVS-1508

 

 

We are having many audio quality problems.  When the TFA is connected to a much larger speaker, it all sounds fine.  We need to turn the volume way down to hear intelligible audio out of this speaker.  

 

Questions:

1. Is there any speaker specific tweaking that should be done to match the amp to the speaker (i2c regs)?

2. Where is that fancy software and eval kit shown here?  ttp://www.nxp.com/video/digital-in-mono-class-d-audio-amplifier-with-feedback-loop-for-low-power-applications:MONO-CLASS-D-AUDIO-AMPLIFIER

 

Thanks,
