Gave it a quick listen and it sounds like the bass has been rolled off while recording. Use a low-shelf starting at about 160 or maybe 200 and boost the low end gently until it sounds more balanced to you.
I would guess that you could boost the low end quite a bit without doing any damage. Eq it first before trying to raise the overall level. Also be careful when doing a wideband boost of the lows as it can begin to mask the mids and highs.
Each recording is different, so just use your ears and make it sound balanced.
