Finding the right subwoofer can be hard but I found some way worth talking about, the Pioneer Competition SPL subs, a.k.a., the ts-w5000spl subwoofer series. SPL stands for sound pressure level, which good subwoofers can increase! These 12" Pioneer subs are top of the line, master subwoofers.

I don't know about you but that looks very intimidating and I like it! If you have ever seen subwoofer drivers, they most likely don't look that thick, remember that is a 12". These are possibly the most powerful subwoofers you can get. Just by taking a glance, you can guess that they handle large strokes. Now if you can't seem to see how this is different, take a look at a more normal shaped subwoofer -

There is a newer version of the competition subs from Pioneer called the ts-w102spl. I am not sure which one is better, the ts-w5000spl or ts-w5102spl, but they are both masters. The ts-w5102spl is inspired by the ts-w5000spl, and is supposed to have new features, and pack in more power according to Pioneer.

I don't know about you, but that is enough bass for one day! If you are the type to already own one of these or one close to this powerful, then count yourselves blessed. I even have some good music for you to test it out with. The song is called "Bass I Love You" by Basstronics. Good luck if your subwoofer can handle it or even produce the sound!
If you can't hear the bass, your audio can't be heard on these low bass tones. Don't be surprised! This is what it does on a Pioneer ts-w5102 subwoofer -
