REW sub measurement- is it ok?

[Mattknz]

I'm still in the very early stage of messing with REW. I'm not sure I really know what I'm doing so I'm taking things very slowly and decided a good place to start was with subwoofers.
I've managed to create some measurements so let's have a look at them.
This is two subs front and rear.

With phase data

What's going on with the phase up to 300hz on the lower graph?


That averaged line looks pretty good to me, is the weird phase on the lower graph an issue? What do I need to do to fix it if it is?

What do the experts here think? All comments/suggestions welcome.

The phase measurement looks wrong, I think, but the FR measurement looks okay.

In general people like to see 50dB scale on these things (makes it easier to compare) like from 45 to 95 dB or so.

I would also like to see the FR with no smoothing, if you are asking.

I certainly am asking

Ok here they are with 50dB scale

and with no smoothing

Тhis looks inverted, check polarity. Also you can invert impulse in Impulse graph\Controls:

Are these subs measured individually or summed?
