Acoustimass Subwoofer has a low "hummm" sound when turned on.


Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.

Try going through this troubleshooting procedure site first: http://logitech-en-amr.custhelp.com/cgi-bin/logitech_en_amr.cfg/php/enduser/std_adp.php?p_faqid=10&p_created=1083625594&p_sid=5*uWZ8vi&p_accessibility=0&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9NzgmcF9wcm9kcz04NDQsMTcmcF9jYXRzPSZwX3B2PTIuMTcmcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9ubCZwX3BhZ2U9Mg**&p_li=&p_topview=1 If you get no solution from this, there are other similar logitech speaker systems that have had similar problems on initial models. Although none appear to be from the z-2300 it appears that logitech have been very helpful with replacing speakers in the past if design is faulty. Give them a try.
