I am a basement with a L shaped room and unfortunately my sub is in the corner. I can move it to the other side of the TV in the middle of the wall but then i lose way too much ULF. I have use the Yamaha YPAO but then their EQ messes with the highs too much. I used the GQ mode to reduce the 63Hz range down on my fronts but it is still way too boomy. My crossover is set to 40Hz. I watched Dark Waters with my with, a drama mind you, and the mid bass was still insane. I have come up with a list of possibilities to rectify this.
- try adding bass traps in the corner behind the sub and right main speaker
buying a new receiver with better room correction. I assume a Denon with Audessey XT is what i need (no plans for dual subs) I am not sure how much control i get with Audessey since i have never used it.
Upgrade my sub to an SB 3000 so i can use the app.
I had NHT Super Zero's and i switched to these Paradigms and now I am wondering if I should have bought the next step down with only 2 woofers in each instead of 3 but it took me too long to realize my amp and cross over were not ideal.
Any advice is welcomed.
I have several suggestions. First, the use of Extra Bass (or "Double Bass") is almost inevitably going to make the bass sound boomy. If you have that engaged, I would turn it off now. Second, I would recommend setting your crossovers no lower than 60Hz. Those speakers don't need to be playing 40Hz frequencies. (Lower than 40Hz actually, since the crossover isn't a brick wall.) Third, you can attenuate the bass coming from your front speakers with the tone controls in your AVR. If I remember correctly, the Yamaha tone controls also affect the center channel.
The combination of 60Hz or higher crossovers, and the use of the bass tone control to remove some of the bass from the full passband (and not just at 63Hz) should let you better tune the sound to your own satisfaction.
I definitely recommend bass traps, but get good ones from GIK or ATS Acoustics. Large corner traps will help to reduce bass reverberation (ringing) down to about 60Hz or so. And, that should also help to reduce the boomy sound you hear. Finally, if you do decide to get an Audyssey-equipped AVR, get one with XT-32.
It isn't just a matter of having SubEQ with dual sub outs, it is also the quality of the calibration it performs. XT-32 is much better. You might find that you also really benefit from using the Audyssey app. That will let you EQ bass frequencies for all of your channels, and then cut-off the EQ above a certain frequency.
As for a subwoofer upgrade, that is also something that you might consider. But, I'm not sure that what you have said so far suggests a real desire for more bass. I think that between XT-32 with the app, the use of your crossovers, and the use of your tone controls, you will already have a lot of user adjustability.
If I were going to upgrade, I wouldn't do it just for the SVS app. I would do it for the specific frequencies I wanted to increase. My guess is that the upgrade would be for low-frequencies now, rather than for more mid-bass. For more low-frequency SPL, I might look at the SB4000, or a ported model, starting with the PB2000 Pro.
I hope that some of this helps!
