Is there any certain genre of music that is much harder for a sub to play than other genres? If I was testing the true capabilities of one before I buy it, then what would be the best genre of music to use (assuming that choosing a song is not an option, only a type o music)?
Depends really. Tonal reproduction of classical orchestral music is tough, and for speed and transient responce, certain newer metal bands with fast kickdrums can trip up a driver.
Dream Theater Tool ("Hooker With a Penis" has the most incredible double bass and complex bass mix in mid song, I use it to trip up everything ) Pantera (Far Beyond Driven, and beyond. Their first 2 albums weren't so deep)
We use Dream Theater a lot in testing our prototypes. I also like the brute-force technique of testing... throwing simple bass CD's at it... And I don't mean the piddly sort of things that have your midbass speakers thumping... I mean the true, bottom-octave, seat-frame-shaking earthquake type of stuff... B)
I wouldn't say hooked... It is good and it is awesome for showing off midbass/subass, no doubt. But if you were to climb in the Nat right now, you would find Pantera, Far Beyond Driven B). It is great for new music, but notthing gets me going like old school Slayer, Pantera, Motorhead, real Metallica (pre-newfag... uh, Newstead), Metal Church, Exodus, Flotsam and Jetsam, Venom, Iron Maiden Etc... Oh, and Tool is God.
Excellent, a new old school metalhead!!! Don't let Geo fool you either, he is an old schooler as well.
