This is kinda funny... the power of bass...

[itschris]

The other day I see my wife tinkering around in the art glass cabinet that's waaaay too close to the system. She finally yelled at me and our daughter for screwing with her an rearranging her art glass. Christina and I both sorda looked at her and were like "whatcha talkin bout Willis?"

She was sure that one of us kept moving around her pieces just to make her think she's crazy. I got up, looked at the cabinet and couldn't figure out what she was talking about. Well this morning, I looked at the cabinet. All the pieces were huddled together!

Then it dawned on me... the vibration from the system is causing the glassware to move together! It happened again after Iron Man and a solid hour of LIVE's Distance to Hear disc.

I'm not gonna tell her.

Excellent, Chris!

It's all fun and games until one of the pieces gets chipped...and you wake up to the sensation of being jabbed by an ice pick.

Bass can be very powerful. Big stacks of scoops make it so windy in a room that baggy pants blow and skirts/dresses press into their legs. Never seen a skirt blow up unfortunetly.

Strangely the damage you do to your hearing manifests itself in high frequency ringing rather than low frequency, so you think it is the highs doing the damage but I'm pretty sure the lows are just as bad. That "fuzzy"/"warm" feeling you get and that pressure in front of your eyeballs probably isn't good yeah? haha

If you put some thin rubber down on the base it should keep those from moving around too much mate.

I'd find my speakers in the bottom of the pool before anything was ever done to "ruin" the aesthetics of the cabinet. I already broke one, but it was a cheaper piece. The ones moving around now are the $300+ ones. Maybe little rubber anti-slip stuff just underneath each piece might be called for.

I have a butlers station in between my kitchen and my dining room which has glass shelves, and I keep my glasses and bottles of liquor in there as well...

I am always straightening those bottles and glasses out from my subs shaking everything in my house..

Did you guys see Big Bang Theory last night? They put cornstarch and water together were it was in a liquid form and poured it in some saran-wrap, covering a woofer. When the bass would start it would form a solid and jump all around, when the bass stopped it would be a liquid again. I don't know if this was real or not but it sure looked like it. I was going to try it but the wife gave me one of those looks.

Cornstarch and water - that's good stuff. A non-newtonian fluid. Get the mixture right, and you can walk quickly over the top off it without sinking, but you'll sink in if you just stand there. Same phenomenon, I believe, as what was on the show - just a different application of it.

Put two sided tape under them

Short of something fairly outrageous, you are not likely to damage your hearing with bass. It's the shrieking highs that take out the tiny hairs inside your inner earle.

I believe this is a misconception. High volumes of any of the audible frequencies will damage your hearing, its just that this damage will first manifest itself in the upper register, whether or not if the damaging frequencies were low or high.

Why not use an Auralex subdude and decouple the sub from the floor.

I've got the Def Tech 7002's. The issue is really the proximity of the cabinet to the speaker.

View attachment 6398

There's only about 4 feet between the speaker and the cabinet. I wanted to build my equipment rack in a built-in in that spot next to the fireplace that could've housed my stuff and her stuff, but... the foot went down and $2000 later, we have a mammoth glass cabinet filled with over $10k of glassware. Not smart I know, but it's these delicate decisions and comprimises we make that affords us the ability to have the things we want... at least that's how it goes in my house.

 

[AcuDefTechGuy]

Wow, I didn't realize the BP7002 could produce that much bass. So it did all this by itself without a dedicated subwoofer?

Blutack

Get some blutack to keep the glasswear in place.

If you can better issolate the cabinet from the floor that might also help.

The guy I recently sold my sub to has a wall full of glassware. When he fired it up and was playing some bass tones the room sounded like it was going to break apart with all the glass rattling. Didn't sound good at all but he was happy with the sub.

Yeah it did. Nancy spent had rearranged all the glassware... again... and then we watched Iron Man and I listened to about an hour of music at fairly high levels. I have to say I'm quite impressed with the built in subs. Granted it's not the equivalent of 2 mammoth SVS's or anything like that, but I don't feel missing out. I think it could be better... but I definately not lacking.

I'm still entertaining the dual subs in the rear of the room idea. I just gotta be patient until this financial crisis comes down. I'm in the finance industry and these are definately perilous times for brokerage/investment banking houses like ours.

Luckily, when I push my speakers forward in their "critical listening" position, I don't really get any odd reflection from the glass. The granite around the fireplace is another story, but it's not horrible. Putting the area rug down and hanging some oil paintings on back wall did wonders.

You are definitely an audioholic!

And CRAZY.

If your BP7002s are already causing this much vibration to your glass cabinet, what would happen if you added 2 SVS subwoofers?

I would be afraid. Very AFRAID.
