- Excite drums with harmonic distorsion (post reverb). Really helps low drums cut in a mix.
By now, your mix should already sound "heavy" on laptop speakers
That's where I was going to start, pretty much.
It's counterintuitive, but often the way to make BD and other boomers cut through is to find and boost a clear high freq range - even as high as 10K, believe it or not. That gives it a snap.
Along those lines, you might also try running it through an amp simulator, possibly in parallel, to add some distortion.
The other part is the hit-in-chest, which is [EDIT: which *starts*] somewhere around 80Hz [EDIT: and goes up about an 8ve]. That comes from 1) finding and/or clearing (with EQ) a low frequency to boost the percussion, and 2) relatively fast-attack/slow-release compression to give it a sharper envelope. The slow release is really important, because sustained sounds seem louder. Don't be afraid to slam the compressor with abandon.
And then someone mentioned parallel compression. That's very effective, although it's not really necessary when every hit in the instrument is loud, because the point is to preserve some of the dynamics while also giving you a hard, compressed sound.
Gerhard's ideas above are other tricks in the bag, although I've only used multiband compression on entire mixes - i.e. you don't want the low rumbling sounds to trigger a compressor on the entire mix.
...or conversely maybe you want the compressor to pump with the bass drum. That can also work.
Finally, sometimes what sounds like missing boom percussion is actually that the whole mix wants to be punchier. That's usually compression and limiting.
Hope that helps.
