Leveling out bass booms

Is your room well treated with bass traps? If not, then it may just all be in your head, or in the hair around your head.

Dean's point is important. First step is to make sure the "booms" you're hearing aren't the result of room resonances. Verify with headphones; if the bass sounds more even in headphones, the real problem is your room lying to you.

If it really does turn out to be an uneven track, any compressor can smooth it out. If the compression affects the bass tone too much, making it sound dull in places, try a multiband compressor with a band tuned fairly sharply to the offending notes. In extreme cases I've augmented compression with volume automation.

HPF at 75Hz +/- will yield more 'apparent' loudness and less mud, though some basses have kick simulations that require a lower HPF (45-75Hz)

Boost11 or a comp without squash since ...

Dimpro basses don't have much timbre; some are like florescent light hums ... and most are already squashed to taste, iirc.  I'm not sure they even allow for compression ... perhaps just volume envelopes for those off frequencies.
 
Consider ARC correction software instead of costly bass-traps and/or unsightly room treatments.  (Bass reflections are probably the most unforgiving DAW problem I have and requires ARC in my small studio.  IOWs, bass traps don't even work effectually for me in my small studio)

+1 on this good advice from Philip. However, there are two things I might do differently depending on where the issue is.
 
1. Take the advice of all the other guys before me in this thread as they have all mentioned affective ways to search with this and deal with it.
 
2. Just about all bass guitar or low end left hand bass notes on synths etc, should be high passed at about 80Hz for a starting point as most of them accentuate 70 Hz to about 100 Hz. There's just about no bass sound that doesn't need high passing in those areas other than those thin slap bass type sounds. You may get one that needs high passing from 90 or 100 Hz...it depends. For the sub low type sounds...yeah, as Philip mentions, you may need to go down lower with a looser (smaller) Q for the high pass.
 
3. Once you find out if this really is a bass issue, I'd not use Boost 11 simply because I don't like the sound of it nor do I like the artifacts it can give off at times. You'd be better off using a Sonitus compressor for starters since it's a bit more subtle than a limiter, you have more control and you may just want to have a bit of dynamics in the bass...especially your touch sensitivity. Too much limiting will kill that and make it sound more synthetic.
 
4. If you are still having the problem, try the Sonar LP 64 Multi-Band. This is great because you can set it for offending frequencies and keep them in check automatically. I much prefer the UAD Multiband for this sort of thing as it is more transparent and works differently, but the Sonar plug is really good too. It will just compress the frequencies that lash out without killing the entire track. Or, you can set it up to control the whole track if you wish dialing in multiple frequencies. Hope this helps...good luck!
