First post here, (except for the padding 5)

Sorry to jump straight in with a request for assistance but I am in need of advice and quick.

My daughter wanted something for christmas to play music on, I had a budget of about 150 euro, she uses mostly youtube on her laptop through HDMI to her tv. It is tinny as hell and she wanted bass. I showed her 5.1 systems at pc world, she was not impressed. Neither was I to be honest.

I bought a set of mission 701s for her from the bay and an amp. The 701s came and look great. I hook them up and there is great sound until you try the bass. It sounded like a skeleton masturbating in a steel box while on meth. (HT harry)

One of them was vibrating like an Ann Summers party gone postal, I was cringing.

Anyway, I'm a bit drunk, (please note the time and date).

I have found the culprit. The driver has 4 screws, one of them has been overtightened and has no tension at all. It just turns. Pretty pissed off at the seller but I have to get this working so I'm not returning them. When I press the offending bolt with my thumb the speakers sound excellent.

I have never opened a speaker in my life but I'm pretty mechanically minded and have a good toolbox.

Some questions.

1. When I remove the 4 torx bolts, will anything spring out at me?
2. Is there a gasket/sealant on the unit?
3. Is the box made from MDF?
4. Is there a specified torque for these screws?
5. Will a split match and a dab of pva be enough to fix the stripped screw tension?
6. Is there anything else I should do while I have them open?

Many thanks for any assistance.
