Guys, I'am starting to use REW and the UMIK-1 and it is great fun.

I've measured few minutes ago an ultra low cost one speaker large range unit and I obtain something like that with REW. I was waiting for some catastrophic measurements but it is not so bad. Anyway I am really a newbie in this domain, so really would like to know your comments on the following graph:

Is this a single sweep or MMM RTA? Of one or of both speakers playing?

I suggest you measure one speaker at a time using MMM RTA pink noise as shown here. Re-post your mesurements for left and right channel with 1/6 smoothing applied and with vertical scale of 5dB.

Judging by this your speakers should be able to provide decent FR once EQ-ed.
