Hello again,

Set up my BFD today and would like some input. Here is what I started with:

Front subs:


Rear sub:


Through moderate low boosting (I know it's usually not recommended, but the concensus seems to be that it's okay if it actually helps), I was able to get it truly flat:

Front result:


Rear result:


Now, as most will agree, it sounds lacking. Should I apply a house curve? Is my boosting okay, given the graphs to show the result? Both amps are at only 1/2 volume, so headroom should be okay? Please advise.

Thanks,

Joe

P.S. - I calibrated the RS digital SPL meter in REW, but did not load the correction file. Is this accurate (being I compensated it in REW), or will I have to re-run it with the correction file loaded?

Wayne,

Thanks for the reply. I did fix the graph scales in the original post. Do you personally think I should try for a house curve? I had to boost the low end and cut the higher stuff already, so I'd have to do that even more to apply a house curve. I think it may sound better for music though. Thoughts? Any thoughts on whether I should load the correction file, or is it enough simply to calibrate the SPL in REW?

Thanks,

Joe

Brucek,

Not to sound terribly stupid or anything, but what does the impulse resonse application tell me? I hit "apply windows" as suggested (left all defaults in place, jut applied). I searched the help files in REW, but it wasn't in depth about using the .cal files. Also, the .cal file for my meter placed the black line on the graph. What do I follow now? Can you look at my modified graph and advise?



Thanks,

Joe

Brucek,

Thanks for the info. I guess what I'm asking is this. Once I load the calibration file and apply windows, I will likely start over. What type of curve am I after? Should I follow the original blue target line or the black SPL calibration line? Does this mean that there is already a house curve built into my "after" graph (since I didn't use the .cal file)?

Sorry for so many questions, just want to get this right,

Joe

Wayne,

As always, thanks for the info. The graph in post #5 is the existing graph with mic calibration added. When I added the calibration file, the graph itself didn't change (it just added that black curve to the mix). You mentioned that once I loaded the calibration file they would be correct. Can you elaborate, since the graph is the same even with the file added?

Thanks,

Joe

P.S. - Reason I am asking all of this is that it sounds sort of dead on music (you have to really listen to pick out the sub material. I prefer them kind of hot in the low end. I don't know if I did something wrong, or if this is how a balanced system is meant to sound...

Brucek,

I did exactly what you instructed. The front result graph in post #1 (before .cal) looks exactly the same as the graph in post #5 (after applying calibration and impulse windows as instructed). Am I missing something?

Thanks,

Joe
