Cheap tweak from Virtual Dynamics:

Sorry, Grant. I got carried away with other tweaks in mind. Sometimes my brain gets ahead of me. (O:

Thanks, Grant. I did start this thread, but I'm looking forward to some more positive posts( or negative, if that be the case) from others. Sometimes I feel like I'm talking to myself. Hey, wait a minute! I DO talk to myself! Anyway, I'd sure like to hear your impressions when your Fat Wrench comes in.

This thread made me wonder if my Dali Megalines might benefit from torquing the woofer screws. The ribbons are suspended in space, so they are non adjustable.

I removed the top section grill cloth on each side (of the six sections) and located in my tool chest, the Torx star bit that fit the mounting screws.

I was surprised that with all my strength I was unable to tighten any of the screws on six woofers that I checked. Granted, I gave up before testing all 24 woofers, but it appears that in the case of this particular speaker the screws have not backed off, or perhaps the factory applied a bonding agent, set the torque and it resists further movement.

Whatever the case, it was a grand experiment and got me to vacuum those dusty grill cloths. I'm looking forward to reports from others on the benefit of this. I love cheap tweaks that have potential to improve sound.
