What to use to weight down your subwoofer (1 Viewer)

[farnamT]

I got an Earthquake MKIII and the sucker physically shakes on my carpet when hitting deep bass. I hear shaking is not a good thing and means loss of DBs. So what can i do to stop this shaking.

some people have put sandbags on top of them. They cover them in a cloth so it doesn't looks quite as bad, but it still is pretty eyesworing. I have seen people put they're heavy amps on top of them. Mayber a paving stone or something of the like. Use the imagination.

I put a 50lb+ amp on mine (the same amp that powers it). Works very well.

 

[Jeffrey Noel]

I don't need to put anything on it. The box itself weighs about 60 pounds, so it doesn't do a lot of moving!

Well, my 15" sub weighs 70lbs and I put about 20lbs of sand bags on it.

Sub is also on a custom cut 3" thick granite slab, with blue-tac between the granite and sub itself.

You may also want to consider a better sub cable, as my Bolder cables (89259 Belden) with Cardas RCA's had more of an effect in tightening up the bass than anything listed above.

Good Luck,

My sub weighs around 200 pounds so I have not had much trouble with it moving around . One thing to consider when putting your amp on top of the subs is that the enclosure vibrates, so it might shake something loose in your amp. I had my amp on top of my sub and it buzzed.

Where can you get a custom Good looking ROCK SLAB that weights 20-30 lbs? And how much do you think it will cost. My sub weights 74 LBS, its no light weight, but the high excursion drivers shake it pretty good. Any thing i put on top of it slides right off.

I used to put two different phone books on mine and claimed to the Ex that this was a great place to put it and it helped quite a bit until I made two much better subs.

That's funny. I have the opposite problem. Any ideas to keep my sub from making my building shake?

 

[James Bergeron]

Didn't ever even think of doing that. My sub is 90lbs and the cabinet doesn't even vibrate, seems to be built like a tank

 

[Chris White]

A small palm works well for me.

I use another subwoofer.

I used spikes to stop lateral movement. My current subs are extremely heavy (over 200 lbs each) so they don't hop around that much. You can get granite slabs from any counter top installer ($$$). In the past I've built a squat wooden box and filled it with play sand. Properly finished this blends into the room nicely.

i use my whole house. (at least the part the IB is screwed into) like Martice said- heck with the sub, how do you keep the house from shaking?

I used to use a 100 lb hexhead dumbbell. I painted it black with red and blue trim and it actually made the woof look more powerful, kinda like a regular woof on steroids.

I made sure the 100 was in bright red.
