Only did a couple of test plays on it Hulk and Tron and it sounds great. A much better match to the PC13-Ultra than the mirage was. It also is only a little bit bigger in size to the mirage.
How do you get any bass out of your subs, when Audyssey
set there levels at such large negative numbers?
You'll need to go back and rerun Audyssey
again, but first you'll need to make some adjustments.
From Big Daddy
1. On the back of the subwoofer, turn the level to around 50%.
2. Set the crossover dial on the back of the sub all the way up to its maximum point.
3. Set the phase to zero or positive.
4. Place the subwoofer in a corner about a foot or so away from the walls, preferably in the front. A subwoofer in a corner will be very loud. If you move the subwoofer away from the corner and to the middle of the room, you may not hear any bass.
5. After you have made all these adjustments, run Audyssey
6.If Audyssey sets the level of the subwoofer to a very large negative number such as -10dB or -12dB, go back and turn the level on the back of the subwoofer down to around 30%+/-
. If Audyssey
sets the level of the subwoofer very high such as +10dB or +12dB, go back and turn the level on the back of the subwoofer up or move it to a corner.
7. After you have made any manual adjustments to the subwoofer, you must run Audyssey again
