Best way to clean speakers

Cleaning- a little lestoil and a lot of elbow grease, 3x a week.

Retorqueing- twice a year w an impact wrench should do 'er just fine!

YMMV. I hope.

I have used a vacuum, with an upholstery brush and the port on the vacuum open to allow as little suction as possible, to vacuum dust off the speakers. However, I rarely do it. And, I don't think its really necessary. You won't hear the difference. A slight turn of a screwdriver once a year is plenty.

He means a torque wrench definately not impact.Good luck,B
