Apologies. This was the "subwoofer" setting. I did 2 512k sweeps from 0-200KHz. The different graphs relate to various gain levels and crossovers.First you have to tell us what we're looking at?
It was sub + mains.So, this is the subwoofer without the mains, or the mains without the subwoofer, or subwoofer + mains?
It kind of is in a corner: well, by a recess but turn it up I will!Perhaps not, but in your situation it isn't doing its job, and maybe a result of having the volume to low. The spec on the BK XLS300/PR is 20Hz -3dB. You aren't getting that. Your best extension is about 25Hz. It should be better. Locate the sub in a corner and see if you can't excite your room a bit more. And turn it up.....
Well that will be goodAs long as your crossover is 80Hz or less, you won't localize the sub.
I couldn't find the embarrassed smilie but thanks for that I will bear that in mind!BTW, the Measured tab in REW is for overlaying and comparing graphs - rather than posting multiple plots, one plot would make it easier on you.....
Yes, 1/3 octave smoothing.These graphs all look like they have smoothing applied. Have they?
Thanks for your feedback.Well, your room is certainly cooperating, as you have no real problem modal peaks with a smooth response and crossover region, but your low end extension isn't what I would expect from that sub. It's stopping quite consistently at 25Hz rather than 20Hz ........ other than that the response is quite good.
