DefTech BP7000sc knocking sound from sub
bad news for me, my DT started a knocking sound on heavy bass parts....At first I thought it was an imperfection in the source material. I was watching a movie on cable. I soon realized it was my sub.
It was making a knocking sound and then it would cut out.....with no source material I could tap the back of the speaker and tell the power was trying to cut in/out, but the knock noise was the giveaway to something being amiss.
Never had any trouble with these speakers at all. Doing a little research on knocking noises from subs I've read something about "spider webbing" coming loose behind the sub as a possible culprit.
I did pull the cover off and didn't note any visual damage to the outside of the sub speaker.
I have no idea how to pop this thing open for further exam and am a noob at technical diagnostics.
Any advice or ideas?
What should I do?
