Guys, just bought and hooked up my Dali suite 1.2 sub with my Yamaha RX-V663 AVR. Until this point I was running my Axioms without a sub. After being done with running a monster THX sub cable to LFE input of the sub from my AVR's pre out for sub-1, turning the sub on in AVR settings, and setting the cross over at 80Hz. All I am getting from my sub is a very very muffled, barely audible sound (which cant be called bass) even with the sub volume turned on to max, frequency (at subwoofer) turned to max and playing my Yamaha at -5dB (can try higher than that but my neighbours may not like it because the rest of the speakers are certainly doing their job). Seems to me that the AVR is doing its job because the sub goes from 'standby' to 'on' which tells me that my AVR is sending LFE signal to the sub, but there is something going on with the sub. Tried unplugging/plugging the sub, pushed the off/stndby/on button to on etc., but no luck. Does anyone have any ideas. I am planning on taking my sub and AVR to a friends place later today to check out if it is an AVR issue or a sub issue but any ideas will be appreciated
Hopefully the sub isn't hooked up out of phase:

Is it a new sub or old sub? Have you used it before?
You sure you have it hooked up to the LFE out and not to, say, the Center out? Easy to hook it up to the wrong one.
It is a brand new sub, opened the box yesterday. Connected using RCA coax, so I am not sure how I could have it out of phase?
If it is indeed hooke3d up to the sub out on the AVR. I would suggest, as Tyler did, to take out the woofer and make sure it is wired in phase.
Or you could just flip the phase switch. A tad easier than taking out the woofer, no?
On the AVR side, It is connected to pre out for sub using an RCA coax and on the subwoofer side to the LFE in. Are you suggesting that I open up the sub cabinet to make sure it is connected properly? I would go with kcarlile's way fo phase change then :).
If you haven't already, check to see if your main speakers are set up as "Large" in your receiver's settings and if they are change them to "Small", that should redirect more of the lows to the sub.
I didn't know the phase switch could reverse incorrect wiring in the box?
The phase switch merely switches the polarity of the wiring in the box, so yeah.
I should trademark that phrase.
What source are you running?
I was running DVD. Had a pro look at it and the sub definitely has some issues. I am getting it replaced under warranty.
Thanks guys.
