Any comments on this graph

Hi,

I have a new SVS 20-39pc+ that I am trying to setup. This is my first time using REW and I am not sure how this graph looks??? This my sub w/ the mains, any suggestions? I have tryed to flatten the response using the phase, but to be honest I am not really sure what I am looking for.

Thanks,
Terry

The phase affects the area around the crossover frequency.

So, if your crossover is 80Hz, then make adjustments to the phase to get the smoothest transition between the sub and mains around 80Hz (~70Hz-90Hz).

Overall your response is very, very good......

I am using the bass management in my amp, it's a Denon 3801, it is supposed to be at 80 but when I ran just my mains it appeared as if the crossover is closer to 70. I think that this is the smoothest response I can get. Would I get any benifit from a BFD?
My setup is in the living room and I cannot move anything else around and I cannot add any bass traps or other treatment.
Is there anything I can do about the null at 23hz? I have the SVS setup for 16hz, it is much flatter than 20hz in this room.

Thanks

Not that you'd notice.

It's hardly deep enough to even talk about.

Thank you very much!
Maybe now I can stop obsessing and start enjoying

Luckily for me my wife has been busy studying for an exam so I have had the last 2 weeks to "play" without interruption
Now I must resist the urge to tweak it more because I know I will screw it up somehow…

Hehe excellent!

I also recently got to the point where it was so good I was afraid to tweak anymore in fear of ruining it!

I recently also tried toggling the BFD on and off....oh boy what a difference. I truely can't thank this forum enough for the wakeup call I got on bass and all the things I've learned - and still learning

I have one more follow up question.
With the setup I have above I am finding that music doesn't sound as good anymore, is this where I should be using the "house curve"? I primarily use itunes for music should I just play with the EQ to see if that helps?
I watched Stardust last night and it sounded fantastic! I am not sure if it was just this movie or if it was the tweaking or both but I found the range in this movie to be remarkable.

Thanks again!

Don't take this the wrong way, but have you found this problem started after you changed to itunes music? I wouldn't really qualify any encoded music such as AAC (.m4p/.m4a) or .mp3 etc as critically listenable. These formats are great on the go, but have you tested your system with a CD and still find that it 'doesn't sound as good' ?

I think you'll find that a simple tone control adjustment can offer the same effect as a house curve. Most receivers still have tone controls or loudness buttons. Have you given that a go?
