Sanity check: Bad Sub ? (REW Sweep results)

[shadyJ]

The measured response is largely the room. The sub probably measures OK. The dip in the response at is probably the distance difference from the port to the woofer, or maybe the port is over-represented. If you want to be sure, do a near-field measurement of the port (like 1 or 2 inches) and then a near-field of the woofer. That should at least tell you if one of them is misbehaving.

Did you measure that sub? Gotta link?

So you moved the better speakers to the front of the cabinet to avoid reflections?

The new speakers' fronts are slightly in front of the cabinet, and at the outer edge of the wall. They are 10.5" off the back wall, KEF says something like 9" minimum, and recommended I stuff the port with their provided paper muffle (which I did). The new sub is about the same width as the old so should fit i the same spot, but unlike the old which is downfacing will face outward, so won't be in a cave of sorts from the furniture.

The center is right at the front edge of the glass top.

I may try putting the sub outside the towers, which would look better, but the seating in the area is at or somewhat outside where they towers are now, so that would make the sound at the outside seats worse, I think, if they are put in closer. As it is, they are a bit of a road hazard of someone going around those corners.

In this shot the console is probably 4" further forward than I hope to get it, I've got some balled up sub cable (it's like 30' and really heavy) that I need to fix by buying a new coax cable, which this is a good reminder of, thanks.

Advice welcomed.

I think you need to ditch the remote sub idea with the all in one unit and when the new sub arrives and after best placement is determined get a separate RF unit if necessary. Low frequencies and rooms are the nightmare that ruins good sound and I wholeheartedly commend you for the effort you have made, not many would have dove head first into this hobby at the beginning of their journey.
