Okay, I know tons of douchecore bands have like a million bass drops in every song, but seriously, be tasteful, I don't want Thy Art Is Murder or bs like that, I want death metal, industrial metal, doom, prog, etc. that'll push my subs to the limit.

The last two Fear Factory has some bass drops, Chimaira's The Infection has some (maybe that's too 'core' for you).

vader (bad audio quality youtube link, but you get the idea)

not death metal but certainly related is the Control Denied album. Bass is serious on that one. You might think they are too "core" but Whitechapel has some serious bottom end to it (along with Bozeman's growl). The last few Amon Amarth albums got some good double bass going on.

These are some of the most bass heavy dm albums that come to mind (production wise) at least without just giving a bunch of slam recs.

Iniquity - Serenadium
Illdisposed - Four Depressive Seasons & the Return from Tomorrow ep
Suffocation - Pierced from Within
Pyrexia - Sermon of Mockery
Infected Malignity - The Malignity Born From Despair

Cephalic Carnage's Lucid Interval album has bass drops dispersed throughout the album
These two songs kick major ass

Meshuggah.

Aborted.
They have a couple of bass drops in Global Flatline (most notable one being in Origin of Disease) but they use them in other albums too (I am pretty sure there's one in Meticulous Invagination off Goremageddon).
Definitely a band that will destroy your subs.

I love almost all of those, except Whitechapel is assanine bs come on.
I love me some 'Shuggah, but I really really really really really hate core music, same with "djent" which is basically core music trying to cover it up with really lame Meshuggah cloning.

You NEED to buy/steal/download The Monolith Deathcult's "Trivmvirate" this second. When you do, play the track "Wrath of the Ba'ath" to see what your sub can do!

Aight son, I'll check them out.

I've noticed Retch has some damn good double bass work.
Toiletcore, but still.

Weekend Nacho's Unforgivable has the production equality of a nuclear bomb being dropped. I am definitely a total sucker for it but it's just so damn heavy. Listen to the title track and you will understand.

Pretty cool actually.
Grind is the only core thing I can tolerate.

Nile's in their darkened shrines has a ridiculous low end production.

coffins

Coffins is pretty sweet, but of course I know about Suffo.

Katalepsy's Autopsychosis pounds my sub in the car pretty damn well. Also, try something from Hail Of Bullets or Binah - Hallucinating Ressurecture.

You need some Mortician in your life.

I fucking love Mortician.
I'm almost wanting something with some bass drops, but not generic as fuck deathcore.
That is, if there even is good deathcore in existence.
