Hi Otto, and thanks for the welcome and quick reply.

I do understand that REW only makes provision for one mic, but actually want to measure using 2 mic's to "acoustically" average the response. As far as REW is concerned this will still be one measurement. For now I have decided to stay with one mic (make the variables less).

The +6db boosts were applied at 32.9Hz and 44.9Hz. My cut filters are currently set at 23Hz and 72.9Hz, although I realise that the mains contribute a lot at his point as well.) I am using the standard 80Hz crossover on my processor (24dB to SUB/12dB to mains).

The 22Hz peak has forever been a problem in my room, and is definitely related to the size, which is 8m by 5m by 3m. My room is the typical shoebox shape.

Yes, sorry, my mains are on. I actually wanted to see the full response and integration between sub, a Revel B15, and mains, B&W N802's. I have tried a lot of room placements but in order to minimise dips in the response I always end up in the front corner, a couple of inches from the front wall. Although this creates significant peaks the dips are a lot less in this position.

The volume of the SUB is set at 70% at this stage, but this is mainly to prevent my processor from clipping. I do not hear any stress from the subwoofer, and listening to stereo music it actually blends in quite well (transparent) with the main speakers.

Again, thanks for the advice; I will confirm the order for my BFD now!
