Mixes not having enough power

If the client says the mix isn’t powerful enough what should I be listening for?

Could be a problem in different areas depending on the client…maybe an overall loudness issue or possibly the low end not being present enough?

Thanks for the advice! I’ll look at those areas. I use your template system and both The God Particle and Orion and can’t thank you enough for all the tips you’ve shared, truly changed my mixes! I wonder if it’s a certain frequency they’re looking for?
