This is my first HT attempt so any advice is helpful. I currently have: Yamaha RX-V530 Receiver JBL NSP1 II Speakers DLS 10 Subwoofer PlayStation 2 (Temporary DVD Player) I have used Video Essentials to calibrate all channels to 75db using a Craftsman SPL meter. Here are my issues: 1. Surround speakers are not very noticeable playing both DTS and DD. At higher levels, Ref -20, sounds pretty good. But Ref -25 or -30 sounds pretty weak! 2. Subwoofer doesn't seem very noticeable too. I don't really feel it. Any advice? I'm waiting for a new amp from PartsExpress for the sub also because of the Auto-On problem. Does it have to do with the DVD player? I'm going to get a Panasonic DVD-S35 soon. Will that improve the audio? Any help is much appreciated. Thanks!
