Lead shot questions

I have a few questions about lead shot as mass loading for speakers.

Is the shot placed loose internally? Bagged? I really dont like the idea of stacking bags on top of the speaker.

What do you do with the acoustic-fil or liners?

Any pointers on getting the shot inside the speaker? Woofer removal, or input terminal removal, or just a common sense lowest point available?

Lastly, with my B & W CDM-9NTs, do you think it would be a worthwhile endeavor?

Thanks in advance.

Elizabeth is right dust would be dangerous to young childrens nervous systems. It may also make you snap for a moment in a rage of anger, & who knows?

First pick up a pair of Sound Anchor Cradle style bases for your Cdm-9nt's, then going from a Bryston 4b-st, to 7b-st mono's will really open up the 9's BIG TIME!!!

The Cdm-9's are fine as is no need to mod them, they just need a major amount of juice to really open them up. I used to own a pair w/ a 4b-st, & 2 Rel Strata III's. Once the 7b-st's where in the system I never felt the need to re-connected the Rel's.

Good Luck!

If I hadn't upgraded to Talon Khorus's, I would have upgraded the cheesie binding posts on the Cdm-9nt's to Silver WBT's. Then while inside I would have re-wired them with siltech wire with an iternal jumper. I really don't think 9 pounds of lead atop would aid this speaker.

The Sound Anchor Cradle 9nt bases weigh in at about 22-23 lbs., & come with 4 adhesive Blu-dots that really anchor the speaker base to the stand with 3-4 points. They also spread the base width to 12" x 14". This really isolates the speaker from the floor, & really tightens up the low end.
