Hi Guys, I actually need some help. Recently my AVR Onkyo 609 died (it was set up by AVR Home cinema specialist), it was running 5.1 B&W Speakers and Sub. I also had an amp running my CROWSONs transducers for two sofas. When i bought my new AVR Onkyo TX-NR646 and set it up. I don't think I'm getting the same "correct" amount of Bass/Sofa Vibrations as i was getting before on quiter sounds. I have setup my AVR doing the following: Crossover for Subwoofer 120Hz and the speakers 80Hz each. Does that sound right? (I'm not sure what my old settings were). One new setting i found on my AVR was Phase Matching Bass, its really great as it adds oomph to really low/quite sounds. Maybe like a door suddenly opening, i tried it with this and without and when using without you don't feel anything at all when the door opens in a scene from World War Z, however when this mode is on, you get a tiny judder which is very effective. However, the issue with setting this mode is that it adds way too much bass to the already loud/high sounds! Shaking up my whole house in some scenes! Hence, i thought maybe Off was the mode i should select for this! What do you think? Is there any other way i can get the transducers to fire at those small sounds like the door opening but stay the same on the loud sounds like car crash etc...? So the issue I'm having currently is that all loud and mid-loud sounds are fine, but I'm not getting any bass (and my transducers are not working) for the low quite sounds, that you just know should have bass but doesn't. Its hard for me to exactly compare, but to me it feels as if i had bass and transducers working for those quite sounds with my old AVR. The Subwoofer has a dial on the back (Phase something) and the transducers amplifier has another one for LPF. These dials have not been changed from my old AVR so they should not be causing the problem. Also my Amps volume (that is running the crowsons) is currently on full. Any help with this please guys? Thanks.
