Klipsch subwoofer when powered on producing 'boo' noises continuously after short use

I didn't register the product 

I guess your thoughts might be true, unfortunately. 

Thanks

Did you get a hold of Klipsch and ask for a repair ticket? Did you register your product when you bought it?

Some dealers sell a line of repaired factory returns just like yours may be if they decide to just swap it out.

Make sure of what you buy when the price is to good to be true. A lot of the store returns are sold as open box or store demos if there is a mark or two..

Factory repairs are different. Some sell refurbished factory units with limited warrantees.

Not for Amazon return but the Klipsch warranty, will try the local distributor.

Are you within the Amazon return window? Otherwise return to a Klipsch repair center, and ask if it's a warranty repair.
