    Ok, My JBL PB10 is about 5 yrs old........I wake up in the middle of the night and the sub is loudly humming away. My system is turned off.
    I removed it form my system and everytime I plug it in, it has a loud hum.
    Did I blow something? I am pretty handy, I plan to open it up....
    Did I blow the driver?
    Any ideas...................?

    Response from JBL.....I am still covered under the 5 year warranty.

    Good evening and thanks for your inquiry. The JBL PB10 subwoofer carries a split 1/5 warranty, with the electronic portions (amp assembly, fuse, power supply, etc...) covered for 1 year, and the woofer covered for 5 years. If the unit was sold to you approximately 1 year ago, the unit may be close to the end of this warranty.

    From what you are describing, the issue sounds like it is in the amplifier section. I would normally refer you to an authorized JBL repair facility, for servicing, but, unfortunately, we were recently informed that your serial numbered JBL PB10 would not be able to be repaired, as the company that manufactures the main Power Amp Module used in your serial numbered unit is no longer in business. Because of this, we are no longer able to supply us with the main part of the amplifier assembly.

    This is not something we planned on happening, and, because of this, we are offering consumers 2 options. If the unit is under warranty, or just slightly past the warranty, we could replace the subwoofer for a brand new JBL subwoofer. If you can fax a copy of the sales order, showing the date of purchase, along you’re your information (name, address, phone #, e-mail address), I can begin the return process, if the unit is under warranty.

    If the unit is more than 6 months out of warranty, they would have the option of purchasing a brand-new JBL subwoofer (the new SUB10 would be the direct replacement) at a reduced price. Take a look at the new sub on our website (http://www.jbl.com ).

    If the customer wanted to purchase a new subwoofer, we can sell a brand-new JBL SUB10, which would be the current comparable model, at our accommodations price ($168.75 plus tax and shipping (for a new SUB10 or $138.75 plus tax (if applicable) and shipping (for a re-furbished SUB10)). The unit would come with a full Manufacturer's Warranty, starting from the date we process the order. If this option is something you would like to explore, I will need the following information:

    1. Name, as it appears on your credit card

    2. Billing address

    3. Shipping address (if different than billing)

    4. Phone number (secondary # if available)

    5. Credit Card type, Visa, MasterCard, Amex (we do not take Discover)

    6. Credit Card Number and expiration date.

    7. We will need for you to field destroy your subwoofer by sending us the entire cone assembly cut from the frame of the woofer as well as the entire power cord from the amplifier plate to the plug and send those 2 items to the following address.



    JBL Consumer

    Attn: Ed Carter

    250 Crossways Park Drive

    Woodbury, NY 11797



    Upon receiving your package, I will contact you directly to take your credit card information and complete the order process.





    Once the order has been created, you will be receiving a system generated e-mail, providing your order confirmation number. The replacement subwoofer will have a full 1/5 warranty, with your packing slip, and the order confirmation as your bill of sale. Please keep a copy of both for your records.



    I hope this helps.



    Best Regards,
