Nice work Warp...

Brandon... that does look pretty good for a natural response, although it might be a little peaky at 45-50Hz. A BFD would easily level that out for you.

That bump at 45hz could easily be solved with an eq and it wouldn't take much work to get pretty flat resonse from there. Have you tried the sub in different locations?

Thanks Sonnie....

Brandon, you really need to post up some closer up pics of your sub since we routered all the corners before delivery, next to those Ribbon Tweeter Rosewood Songtowers, or I'm going to come over there and reclaim that product.

My preliminary thoughts, the 80hz crossover looks the best. Using the EQ, boost the 20hz range a couple db, then pull down the 40-45hz range about 4-5db and pull down the 63hz a few notches as well for starters, you would have a pretty smooth response.

I'd definitely go 80hz. Even though your speakers may be able to reproduce relatively flat response down into low frequencies, it's best to keep as light a load on them as possible and let the beastly subwoofer take care of the rest. A little distortion from the sub isn't very easy to notice, but a little intermodulation distortion from the woofers used in the speakers created as the result of trying to do too much on the low end while also handling upper bass through midrange will be noticed much more easily.

I ain't seen graphs like that in a long time. You really should try out REW... it will give you a much more accurate picture of what's going on with your response.

Heheheh I got the Galaxy meter and the external SC, but haven't had the time to get familiar with it just yet.... Working on it though.... Holiday season is a bit time consuming for me....

Not sure Nuance has the money for all the equipment just yet...

I've tried it a foot from the back wall, but the response was worse. I don't have much room to play right now, but maybe down the road. To show you what I mean I've attached a pic of my listening room. Sorry for the camera, hence the weird white marks on the wall behind the speakers. Gotta love the oh so appropriate Dora shot, though (I have a 2-year-old).

I kind of felt the same way, so I removed the 60 and 70Hz responses and am using the 80. Thanks, Steve.

True, but I am too poor right now to buy a decent mic. Eventually I'll get there, though.

Thanks for all the responses everyone. My main focus is paying Patrick back for the sub, then it's on to picking up an EQ. Until then, have a happy holiday!
