so i just watched fight club, this movie has some extreme LFE, i nearly thought my subwoofer's woofer would blow right out the front directly into my face several times, many times it got so extreme i could literally hear WUWUMPWUWUMP, mechanical noises from the sub. what can i do to fix this problem? would a second sub help handle the LFE and atleast reduce the problem? i've watched several movies with lots of LFE and this is a first. i like explosions, but not when they are so realistic i have equipment nearly exploding.
That subwoofer's amp is 50W continuous and really isn't enough to do what you want. If the woofer itself was incredibly sensitive, it could, maybe. Another issue is that the lowest -3dB point, which the specs show to be 40Hz, is above much of what a lot of good speakers can do on their own. A subwoofer that goes closer to 20Hz will do a much better job of handling the deepest impulses, like explosions. When the audio has strong signal below the tuning frequency of the port(s), the box has very little control over the woofer and that used to be called 'doubling'. The woofer hits on the note or impulse and it's almost like dribbling a basketball. Unfortunately, it's hard to listen to all of what a subwoofer will need to handle when auditioning. If you own what you were watching, it would be a good test next time.
To answer your question about adding a second sub, maybe. If it was a borderline situation when this happened, it might be enough to keep it from going over the edge but honestly, I think I would look for something that can handle it on its own, with a more powerful amp. Bass frequencies require a lot more power, even though it's a small part of the frequency band.
