My audiophile receiver is sitting on top of my Polk Subwoofer - Page 2

post #31 of 57
If i could take the liberty of a summary from my perspective.

The OP wanted to start a discussion about putting a reciever on a sub but didn't really have a specific question. Members here only picked up on the word audiophile and were more interested in that aspect of the description. Tho OP chose to not backpedal on his post and threw out some pricey polk sub link pretending it was his. Smelling blood, the sharks here gently gave some opinions of polk products not being audiofile quality. The OP came clean that he was joking about the monster polk. And I'm not sure where the last 5 minutes of my life went.

Well, my wife learned not to put a silk plant on top of our Velodyne Minivee , which sounds a lot like your microsub. That sucker flew off within minutes.

Oops, this thread looks like BS, I guess. Didn't read all the posts. My bad for feeding the troll.

It's not b.s.

If it walks like a duck...........

Put your receiver wherever is convenient for you. If you have a problem down the road, you know not to do that. Why is there a need for discussion?

Option #1:
Don't do it based on what you've read.

Option#2:
Do it and come back in 10 years and report that all is still working well.

Rather than using a "salt test", have your wife sit on the subwoofer and see if she sighs, smiles and asks you to turn it up.

Not bs but you did come off like you know more than the so called experts. When that attitude was challenged this thread lost It's focus.

I would like to actually hear a civil discussion on this.
For example, car audio amps are commonly attached rigidly to subs. I wonder to what extent home audio is able to handle vibration by design?

If one has a concern about placing any "audiophile" equipment on top of a speaker or subwoofer, pay a contractor to build a shelf/cabinet and eliminate any concern. Whether it causes harm or not is not worth a lengthy discussion IMHO. Only two options.... wink.gif

Powered subs have rigidly attached amps too. Car audio has it's own forum..biggrin.gif.

I prefer to set a glass of water on my sub cabinet, or table, or couch arm, and watch the water vibrate (or not) -- never tried salt, but I expect the water to better showcase the sound/vibration cool.gif.

Better get those amps out of the cabinet before all the solder shakes loose and they die!!!

I had been told time and time again not to put my receiver on top of my subwoofer. Look at this:

http://www.avsforum.com/t/828700/placing-a-receiver-on-top-of-a-subwoofer-ok-or-not-ok/0_40



I took the bold move of doing so anyway and wanted to talk about it here. Has anyone put some salt on top of their subwoofer and played loud music? My guess is that it won't have a big effect. Someone else here claimed the vibration once knocked a potted plant off their subwoofer.

Regarding using a glass of water instead, how much did the water level move?

Well, you mentioned a 10", 2000-ish W subwoofer. My small sub is 8-in and 1000 W RMS/2000 W peak. The tiny, toy-like cab must vibrate all to hell because that plant did not stay put. My anecdote may count for nothing.

I'll take the bait...I suppose. First, keep in my I have a Seaton Submerssive HP, so a bit different a beast than your sub. Second, keep in mind I'm not exactly calling this a good test of how inert the cabinet is....

That said, when sitting atop the subwoofer, the water was still. When I sat it on my end-table, I could see ripples in the water like a stone was thrown across it when heavy bass notes were played.... It was like a little water-oscilloscope. It made me smile, lol.

If you read it on the internet.... it must true.

Seriously though! If you want to do a "salt test" ot "water test".... go for it. Either one will probably show that there is vibration. So, that's not news. Right?

The next thread you should start is "how close can my sub be next to my TV"?
Quack. tongue.gif

Obviously there is vibration, but how much? I am guessing my subwoofer has less vibration than if people put the receiver on a coffee table that has the subwoofer aimed at it.
post #44 of 57
That would be a bad guess. Still won't cause problems until it breaks.

I want to do a true audiophile test of this. Do you recommend common ordinary table salt, or can I substitute sea salt from the upscale "whole foods" type market? Is there a place to buy audiophile salt for testing purposes?

I can sell you a bag of 'A9X's Awesome Homoeopathic Cryogenically Treated 6 Nines Audiophile Salt ®' for only $1299 plus shipping.
Whilst it's possible to sprinkle it on the top of the sub, that will only potentially show you panel modes and not the actual level (displacement) of any vibration. In keeping with it's Homoeopathic roots, we suggest placing a single grain of salt on the panel of interest (top is usually best) and play Track 2 from Jennifer Warnes Famous Blue Raincoat as loud as possible on loop repeat whilst watching the grain's pattern of movement intently. After 36 hours of this straight, you may begin to experience an enlightenment of the relationship between vibration and your place in the Universe. Or you just want the pain to stop.

^^^I give you...The Rock Salt Device (courtesy of Googling "audiophile salt").

Enjoy your entertainment (this guy is obviously very bored).

I'm pretty sure it won't literally do that.

If you have to ask...

Read this quote from his site and ask yourself again if you really think this guy is serious.


Quote:
I call this one “The Colgate Device”, but it’s just as effective with any other brand of fluoride toothpaste. I got the idea when brushing my teeth at night and thinking, as many people might, “I wonder what the toothpaste box sounds like?”. “Interesting” was the answer, but even more “interesting” was the toothpaste inside the box. I’ve included this in my list of Free Audio Tricks, because it’s something that everyone has on hand. Who doesn’t brush their teeth?

Start by smearing a small amount of fluoride toothpaste on the various hot spots (described elsewhere) located on your audio equipment (ie. near the jacks, on or near the power cable going into the component, the edges of the top cover, back of speakers, etc). Like with everything, the more you apply, the greater the effect. So I think that even those with less refined listening skills, there’s a good chance of catching this one if you apply enough (for those with refined listening skills however, who have no problem hearing its effect, you can easily apply too much!).

Don’t throw the box away, the box is a device too! On some of the newer Colgate (or other) boxes, there is a laser-etched design. If you have this type of a box, cut out a sliver of the carton (about 2mm x 15mm) of a solid color. Simply place this on the Compact Disc logo of a non-playing CD. See if your sound has changed.

(bolding added because I think it's the best part)

Hahaha...you guys are crazy! Thanks for the laughs.... I think I shall try the toothpaste trick, I think it will have the effect of changing the sound drastically...like, maybe so much so that I'll no longer be able to hear it -- I think I will, in effect, transcend the sound. (Well, that or fry every piece of equipment I've slathered it on, lol).

Sadly, I do! I've read things just as silly coming from quite serious audiophiles. So when someone says or writes this nonsense with a straight face, I'm not sure if they maintain that straight face with skill or ignorance.

Wow what a troll thread lol, either way i thought i'd mention that Polk is not considered to be audiophile grade NOT that their bad its just theres better products. Sound is subjective after all but most would agree Polk is no expert in subs but to be honest their higher-end subs aren't that bad for music and they are tight. But when it comes to their actual speakers they're quite good and rated to be good in several non customer reviews(no biased).
