Substitute for lead shot
« on: 4 Oct 2004, 06:12 pm »
I need to fill the bass modules of my VR-4jr's. I don't want to use lead  shot. What else can be used to fill the bass module. I have heard of a steel/metal product that works just a well but I'm not sure who makes it or where to order it.

Thanks for the help,

Gary

Not sure about the VR4 jrs, but I've used sand in tubular speaker stands and it works well.

Micro-Bearing Conductive Steel Fill Material

Great stuff.  Very fine.  Not cheap.  Used this in a pair of Osiris stands.  Give them a call and they will tell you their experiences for any speaker they've ever worked with and exactly as much as you will need.

How come you don't want to use Lead Shot?

Sand would be your best shot as an alternative to lead shot.  Plus it is quite a bit cheaper.

If you're worried about contamination from lead, you can by steel shot or nickel plated lead. I think any gun supply store would have these products.

This type of steel shot may not have the specific properties of the micro-bearing stuff from Star Sound (audiopoints) but would be way cheaper.

Some time ago, I had trouble even finding ANY shot locally; everyone said "Go to a gun shop" but I only found one 25 lb bag (for $25).

There's the nickel-plated stuff
that would seem to be safe(r).

I thought there was something special about lead that made it especially
good for filling stands/speakers????

FYI...shipping on shot is quite expensive...

what makes lead "special" is that it has higher density than steel or any other shot.

Gary,

Kevin @ VSA recommends 50 lbs of lead shot per bass module...of all the shot that is available, lead is the least expensive at around $1/lb...however since you'll need 100 lbs, it'll still be $100! :o

if you choose steel shot, it'll cost you even more.

Gary,

Are you bi-wiring your 4jrs?

I ended up stumbling onto a lead shot "recycler" in a nearby town: it's shot that's collected from shooting ranges, cleaned up and re-bagged.
It was around $12/ 25# bag.

Yeah I only paid $13 per 25lb bag of lead shot.  It came in a variety of sizes too.  From large rounds to very small rounds (think small like ballpoint pen tip and even smaller).

Don't worry about lead poinsoning.   As long as it is inside the woofer module, you won't have any problems.  Just don't sprinkle it on your Cheerios for breakfast and you'll be fine.

Would cheap play sand from Home Depot not work?

Thanks for the suggestions.. Lead shot it is.

Mad Dog, Yes they are bi-wired using the new Jolida JD3000 monoblocks. These amps could be the best kept secret!!

Thanks again,

Gary

Darth, completely off the topic, what amps have you used in the past? I think you've been through a few changes lately and was wondering what you're comparing the Jolida to in your system.

Is the point of the lead shot just to add mass and lower the res. freq. of the module?  I was under the impression (maybe the wrong one) that acoustic energy should be turned into heat through friction inorder to be stopped.  Will lead shot allow for much friction vs. something like dry sand?  Just curious.

darth audio,

the 4jrs are quite impressive speaker once the datalink is removed and they're bi-wired.  

the jolidas sound interesting...will have to take a look into them... :)

Max, I had the Spectron Musician III, listened to the Rogue M150's, a few of the "well Known" tube amps. The Jolida JD3000 has such a sweet sound, very natural. The midrange is too die for. These amps are 200 watts a side using (2) 211 tubes(Sino), (2) EL 34's(Svetlana's) and 2 AT7's(NOS Mullards) per monoblock. I think the Spectron is a great amp.. and I listened to many other "digital"amps. I went back to tubes and couldn't be happier.  :D My system is now all tubes. Just had my EAR 834p phono stage modified and it's using cyro'd Mullaed CV4004 and my Jolida JD100 just came back all modified using cyro'd 12AX7's in it. I love the sound of Mullards.

Mad Dog, I'm using the deHaviland Ultraverve JR. This preamp has BIG sound from Big tubes. Works great with the Jolida JD3000 monoblocks.
