Do the so called spectrum bars at least bounce up &amp; down noticeably?

Yes unless your input say a computer is turned up louder than they can compensate for. Over all great eq. For the price.

Not much. They are soft and made of leather. If you want something that bounces, get ones made of rubber.

Vibration not that noticeable. While they're not light, they're very well built. Excellent value. They were priced such that I bought them and a small clipper for the cost of some other large clippers.

No, I have not seen them react to anything but the music coming through them. Even that has to be turned up and have good bass to get a big reaction.One of our first set had one that didn't work, but it was replaced and they were fine. In my opinion the quality was what should be expected for the price. They are fun to watch.

Yup. That is what I have on mine. I used the speaker spikes included with the stands and everything works well. I've bumped them slightly a few times while cleaning and while they have rocked a little but I have yet to knock one over. I am happy with them.

I have not had any problems. I believe that because they are flush with the ceiling they are okay. If they were to hang down, then that would be a problem. I will also admit that I was not sure if they really worked, but after getting the first one up I was AMAZED at the difference in the amount of glare reduction. I have 12 lights in my classroom, but only use them on 5 of my lights. I tried them on several more lights, but that was too much.

I have had no vibration problems. Once you get them set up correctly they work great.

The bars are too sensitive if the music is little loud then the bars will raise and wont come down untill silent. If the sound is slow as in slow music or talking then it works good.

I am not sure on the spectrum. But they are very bright! We put these on the golf cart.

I find they tend to wiggle out a little bit. They dont fall out, but they do not stay snuggled in tight and require constant adjustment. Sou d quality is moderate considering one is not an audiophile.

No! To be honest I feel like I wasted money on these. The speakers are okay at best. The sub is nice, but it does just like someone else mentioned. When watching a movie, if sound dips or there's a lull. The sub cuts off and back on when sound picks up. So you'll get that blue light off and on flicker. Sometimes even a little thump when the sub comes back on. I do like the size of them if you're tight on space. If you aren't go with some bigger front and center speakers. Hope that helps.

While it is a very sturdy setup, the keyboard tray bounces when I type on it. Even worse, the screen bounces a little bit too. I'm still experimenting; I'm not sure how much a problem the bouncing will be. I don't have the keyboard velcroed or otherwise affixed to the tray, but I don't think this makes any difference: the keyboard tray bounces but the keyboard itself isn't moving.

No, you don't bounce around as much. They still bounce, but it's not as springy so the bouncing is less.

Wish I could help, but I never received all the packages from Amazon and had to return it. Good luck, they looked like the best bars available.

Sorry. I never tested them. But my friend had the same ones and they were amazing. Non-vibrating base.

I am 190 lbs. and have bounced on these bars to test the strength and did not have any issues. I have a few friends pushing 300lbs., but I do not think they have tried stepping on these when they get in the truck.

I've never tried - they've been on since I installed (a year or so ago). I'm committed to the setup since my good old fashioned wired computer is attached to these aero bars. Just speculating but it's probably not that big a deal to switch them on / off (5-10 minutes with practice?) - and as one of the other responders suggested, I expect that marking positions (with a sharpie or something) would really help.
