Subwoofer(new) Making Loud Rattling Noises

Posts: 7
Hi Guys,
I very recently purchased the Polk Audio RM6880 5.1 speaker set. The sattelites work GREAT but the SUB is causing a lot of headache. For some reason, it is giving me the most annoying sound; by that I mean like, you know that the sub is a slot/slit designed one where the air comes out from. It's not a circular hole but rather a slit. From that slit, the air is SO loud that it overpowers even the sattelites!
Is this normal?? It sounds like there is a plastic bag stuck INSIDE the subwoofer and that rattling sound of the subwoofer is making it unusable! What do I do? I called Polk Audio, they want me to take it to this location some 3 hours away and I have to take the bus and carry it with me.
Is there any other possible solution to this? What do you suggest I do? And is this normal??

Absolutely! The receiver I am using is the Yamaha RXV463. It's a fairly new one. Here is an image of the set:

As you can see, the grill on the right side of the sub (the squarish one) the air is coming out of ONE of the FOUR sides of the square. Or was it two?
The only two settings on the sub are Volume and Passive & something? They don't make a difference as the sound is still there :-( -
Try checking to see if something might have actually gotten sucked into the sub slot. I've had it happen with a paper towel i dropped once. Made an awful ruckus.Main Surround -

If the unit is under warranty
It would be wise to have it checked by an authorized POLK Audio representative.
or mail it back to the place that sold it originally to you
or mail it direct with proper return authorization to POLK Audio Customer Service
Confirm and Verify and Document that your unit will be properly received. -
From specs of this receiver:
Yamaha's YPAO Sound Optimization system analyzes the acoustics of the room and adjusts various speaker parameters to provide optimum sound quality at the listening position--all in less than three minutes. Yamahas YPAO system uses a small microphone and sophisticated equalization to automatically set the best sound for any room, no matter where the speakers are. First it checks the speaker connections and phase of each speaker. Then it sends out tones which are captured by the microphone to analyze the room acoustics and sets a variety of parameters, such as the speaker size, the distance of the speakers and even the sound pressure level, etc. It does this until it achieves the best sound conditions for your room, and you don't have to adjust a thing. The RX-V463 has an improved YPAO system that automatically selects the crucial frequency bands for the listening room, and then adjusts the level of the selected bands to create a cohesive sound field in the room.
Make sure you use this feature it really helps. Also, if the sub has a hertz level set it at around 80, I believe this is a good starting point. Sometimes you just have to keep tweaking the adjustments until you get it right. Most H/T equipment that is worth having isnt "plug and play" more like "plug and pray".Polk Audio Surround Bar 360

Well, the place they told me to bring the sub to is really really far from where I life; and to carry such a heavy sub on the bus for 3 hours would be hard.
Could you please give me more details on the "mail it direct with proper return" method? Who shall I contact about this? What shall I do to do this? -

Haha plug & pray...I DID use the little microphone and it was fine but it is not any setting on the receiver that makes the difference. It is the subwoofer itself...the air that comes out makes a rather rattling noise. I cannot describe is more than like a shopping bag was stuck inside it. None of you have had this problem before? I hope I didn't spend $899 on a set with a bad sub :-(. Any tips would be appreciated!Knucklehead wrote: »From specs of this receiver:

I assure you my equipment is set up properly. I am not a beginner when it comes to setting up a home theater. I have tried both methods:
1) Connecting the satellites to the Sub and then connecting the sub to the receiver
2) Connecting the satellites and sub all directly to the receiver.
Also, I spent a LOT of time with my system making sure everything is how I like it. I have tried the woofer with different crossover freqs...currently set at 80 Hz. My apologies if I frustrated you. -

no frustration here....just trying to help. You say the air is so loud it overpowers the sattelites, this is telling me that you sub-driver is working and moving air, possibly not set-up properly.
You asked for possible solutions and suggestions, and then you said you were positive your system was set-up properly......
Shipping a heavy sub back to the place of purchase or manufacturer would be my last resort.Polk Audio Surround Bar 360

How far up do you have the volume?
Can you get access to the inside of the sub? I had a rattly FX speaker one time and it was just a giant hunk of glue that was inside the cabinet. Removed glue and problem was solved. My point is, if it sounds like something is rattling around inside, then maybe there is!

Oh absolutely! I am confident that the problem is not in my setup; it is a problem with the subwoofer itself. I was merely asking for suggestions on the sub itself. The rattling noise is there regardless of the way the system is setup. I have tried it with three different amplifiers and all produce the same result.
I just wanted to see if other people have had this sort of problem before and if so, what they did to fix it. -

Had one of my dogs drop a bag or something she was running around with and it was in front of my sub, well i heard it loud and clear later that day when I put my stereo up and my Velodyne had sucked that bag right up thru its front slot load, unless you haven't look in/at your subwoofer itself to see if somethings inside, you cant make that determination yet.Truck setup

The volume is up just under midway so around 4-5. I believe I can take the cone out and look inside but I do not want to do anything that would potentially void the warranty. It is not so much of an actual rattle, it's more of like a piece of paper or plastic is moving violently inside.
I wish i was adventurous enough to peek inside the sub...:( -
Taking out the driver may not void the warranty. After all, if the driver was dead and you needed a new one polk would have you ship the driver back not the whole sub
-
Can you rock it back and forth or maybe give it a gentle shake and see if you hear anything moving around inside?

I had that problem with my PSW300. turned out the spider separated from the frame. crazy glued it back together. not uncommon. if yours is under warranty, you could just return the driver to Polk should this be the case.
