REMINDER: tighten up your loose screws


REMINDER, tighten up all loose screws around the drivers. Just Do It. All of them.
Sit back and enjoy your “new system”.

85% of screws on my speakers needed 1/8 to pass 1/4 turn to snug firmly and guess this… all screws on my woofers needed 1 full turn. Some was actually needed 2 turns. Anyways, improvement was a jaw dropping.

Good reminder!

Rather than hand tightening driver screws until they "snug firmly" (without knowing if the screws are equally tightened), match their tightness using a torque screwdriver.

Even better, reach out to your speaker manufacturer to ask them for their recommended torque value.

Here’s a good video from Rick Schultz about tightening driver screws using a torque screwdriver.
This is an important maintenance that should be checked a few times a year.
Yes!

My 15" woofers weigh 37 lbs each, plus the mid and tweeter horns. 

And both the front and rear panels are removable with air tight gaskets. 

every 6 months I remove the back, check and tighten anything that might be loose, most often not, but occasionally yes.

I don't have removable grilles, so once a year I take the woofers off the back of the front panel so I can inspect their cone and surround (pleated cloth not foam). Rare from 1958, so I keep a spare woofer and spare rebuild kit ready to go downstairs.

I inherited a very cool antique long screwdriver, it helps me reach and I get to think of Poppy every time I use it.
I had a similar experience with my speaker binding posts between my outboard XOs and the speakers
