Massive Attack's "Angel" is very bass intensive, but I consider "Unfinished Sympathy" being more suitable for testing, as there's a low frequency thud that comes slightly off-beat, and is so low that on many systems sounds washed out.
Enter Shikari's "SSSnakepit" - first 35 seconds literally will push the system to the limit. This is how you wreck your speakers...
Korn's "Freak on a leash" is a nice test as well from the very beginning, especially at 20-22s from the start.
Back in the days there was a hip-hop group called "Nemesis", who literally were obsessed with bass and low frequencies. Basically anything from those guys is nice for testing as the bass is very much synthetic and very low. This is their spotify page.
