With our shipment, a setup sheet was provided. Did you receive the setup sheet?
Are you running a single port open or both ports open. We're setup for single port operation. Do you have Audyssey and have you run it yet?
Yes I did, it's pretty intuitive. Um using 2 ports open/Limiter On/Rumble Filter On/14Hz/Low Damping/LFE Input. I don't use Audyssey; I prefer manual set up. I mean all things equal, this sub just doesn't have that IT factor or may be um expecting a bit too much. The FR is roughly the same between this and DIY sub in the same spot in my room till about 22Hz. But something just doesn't sound right.
It's not the head room or enormous output. It's the SQ that is just not right. If low distortion/clean bass are attributed to this sub, I've heard it in my set up. I fried my iNuke a couple of days back. It should be back from repair shop tomorrow. I'd do an a/b testing with my DIY sub.
I hear this fluttering sound from inside the box during transient peaks. For example, The Conjuring end scene.....there is a very loud sudden burst of low frequency; I hear a lot of fluttering from inside the box. I know it's not the driver bottoming out or cone hitting the magnet. It rather sounds like something is loose in there. May be it's the limiter kicking in or something. Um not sure.
