BA hps10se Subwoofer randomly makes LOUD thud during movies and games. (1 Viewer)

I own a boston accoustics horizon series hps 10se sub connected to an older sony 6.1 receiver through a monster cable 25 ft digital cable.; It sounds great most of the time, but randomly throughout movies, tv or video games it will make a loud thud noise. After the first of these noises they become more common and i usually have to turn the sub off and continue the movie without it. The noise is as if someone had just dropped a big box of books on the ground, very loud and distracting! It happens in both, the always on and the signal only, modes of the sub. I am planning on replacing the reciever with a new pioneer and the cable with a 12 footer from monoprice.com. But I am guessing it will happen with that set up as well. Does anyone know why this is happening? What can i do to fix it? I love the sub and got a great deal on it, so i don't want to replace it! Thanks in advance!

I forgot to mention all the other speakers and klipsch synergy series speakers, so it is the only one that does not match the 5 others.

Sounds like you are bottoming out the sub, literally making the speaker travel till it hits the enclosure. This is a bad thing to do. Dial back on the sub output, or purchase a more capable sub.

I do not think that is the problem as the noise is so random. it does not appear when their is a lot of base, it is entirely random or it seems that way...
