Review title: Cerwin Vega CVHD 5.1 sub-woofer issues
Product review: I purchased Cerwin vega after reading rave reviews at cnet and other sites. I like the sound quality - produces great sound when it works.Noticed an issue with sub-woofer. The receiver volume has to be high for the sub to kick in and then it cuts off after about 20 mins if the volume setting is left as is. So watching a movie, the sub cuts out after 20 mins, then i have to raise the volume for it to start working again.Haven't yet called customer service so can't rate that.
