What are ways to fix speaker dips in my speaker or audio room

This can be fixed at the listening position with DSP at the expense of amplifier power

In fact you may clip the amps with ease yet not fix the problem of a loss of bass. This is because the waveform is cancelling itself out. You can put a lot of power into that and not get anywhere.

That is why I recommended a Distributed Bass Array (multiple subs) since that will break up the cancellation. Then you can dial it in with the DSP if you want, but that will be minor compared to what the DBA will do.

I have recently hired an acoustic engineer and after a day of measuring room acoustics and he came back with what I needed to fix and one of my speakers dip at 54 HZ and would DSP help or a lot of bass traps in the frequency work better?

If you are really talking about a dip of only .8dB at this frequency, its not a concern. Imaging will not be affected in the slightest.

If the dip is 8dB and not 0.8dB, then as long as the speaker itself is OK, its unlikely that bass traps and DSP will help out, since the dip will be caused by a standing wave. To fix that you have to break up the standing wave, and that is done by using at least a couple of subwoofers that are asymmetrically placed in your room (assuming that the main speakers are otherwise full frequency). The asymmetry is what breaks up the standing waves. The subs must not have any output above 80Hz or else they will attract attention to themselves.
