...I don't have the Video Essentials dvd, just Avia and it doesn't have a 'sub only' test tone on it, so I can't calibrate my sub independant of the front speakers, but I know VE Does have a test like this. How would I go about this until I can get a copy of VE? Is it possible to use a combination of Avia and the THX Optimode on one of my dvd's? It has a dedicated subwoofer test tone. Using Avia I could calibrate my five speakers to 80 dbs, and then pop in THX optimode, and set my sub to match my other speakers using it's sub test tone. Would that give me an accurate enough reading as compared to the sub-only test on VE? I hope this not too confusing, any help would be appreciated. ------------------ The Multi Channel Animal's truly, madly, deeply in love with Estella Warren!
