I'm thinking more of something I can build out of the leftover ply, sand, lead shot, resin and other wood I have laying around here The levitating stand will have to wait... Cement isn't so light and can be put into wood.

Active vibe control isn't so straightforward. Even at frequencies just below 20hz requires quite the setup....nothing 20k couldn't solve

Lollers. They could have chosen Obama-bin-laden

Thanks Can I pick your physics knowledge about turntable stands? With the damn springy floor that I've got in the apartment...going wall-mounted would be ideal if not for damaging the wall Of course you can. OK, given my really less-than-perfect environment (3rd floor, carpeted floors, no wall mounting available), how would you suggest building a stand to best prevent outside vibrations from affecting the 'table? I've seen roughly two camps on this, one seems to be using a very light stand that's spiked to the floor, the other involves just getting as much mass as possible and putting the turntable on top of that. I'm no expert in any way but it seems to me the approaches are saying: 1. Remove mass to push the frequencies at which the stand resonates into a higher passband, or 2. Add mass to push the frequencies at which the stand resonates into a lower passband. I would guess that adding mass is a better approach. The amplitude of the resonant frequencies is decreased as mass is added and the passband is pushed down (much like adding mass to a door panel or layers to an enclosure). It seems to me that a large, heavy stand would be much more effective. But Sean might have some different ideas. Mass is cheap and easy and requires no measurements, modelling or tools. I'd say get the biggest hunk of rock that a few of you can carry and set your table on it. A couple airbags or rubber isolators underneath it wouldn't hurt either.

sorry to hear about tucson I'd stop by and visit, but it just ain't that close. If you "end up" that way in the middle of next week beers are on me. I owe you a few.

Mass with isolators for sure. In particular in your case the floor is not so helpful.

OC this week, Tucson next, San Jose the following....geez

Pretty much the only good thing about sleeping in Laguna beach is hearing the waves crash from your hotel bed.

The kicker amps will do power

Not a rattle in my truck and it is one of those cheap ass GM's. Just take some time to do things right and you shouldn't have issues.

Yep not a concern I personally would look for a D in particular for sub duty.

Nice work on the speaks mang.

There is some sonotube in my garage...18" variety.

when you type I regularly read: poop, poop, poop, poop, poop, poop.

PA boo!!! Nice choice on subs though.

I just took out 3 SX amps-(2)1250.1's and (1)700.4 with SXRC and replaced them with Zapco DC 1000.4 with DRC-SL & 9.0the SX are decent in my opinion but really don't even belong in the same sentence with the Zapco's I'm not talking down the Kicker amps but my experience with Kicker SX -vs- Zapco DC Ref or C2K it is not even a little close. I am very curious, what exactly about the SX isn't up to par with the Zapco's in your opinion?

I know all the features and still don't care, amps should be amps and that is all I need.

Your JL amps have almost as many features built in as the Zapco DC's just not digital The only reason I own mine was the price, a good hookup surely doesn't hurt. My guess is I paid less for my pair than you for your sub amp...how could I say no?? I only use them as gain blocks though

Yummy for old Zed.

I can buy a ZX750 and take a shit on it and sell it to you for the price of the eD. Personally I'd rather have the amp with shit on it.

Where did you hear this? I've never heard of any enclosure with a cut off at 50Hz. Maybe an 80Hz cut off, but I've never heard of something that low. Hear this??? Hell I know this, I wish my subs only had to play 30hz on down but regrettably my front stage isn't that good

And shit, I was just in San Diego today and could have stopped in.
