Using the Stereophile test disc and my ears, it sounds as though I have a room dip between 70 & 150 Hz. The bass comes back with a vengeance below 50 and extends (although with roll off) to 31 Hz where it is still audible, but much reduced in amplitude.
Because my speakers are stand-mounted "bookshelf" units, I'm assuming that the dip is an artifact of the distance of my speakers to the floor?
Other than using a subwoofer, or TACT style equalization, are there other options to smooth out the bass?
Thanks - Boomzilla

These could be your room modes. Time for some bass traps. EQ is just a crutch.

And you need a meter, not your ears, to be sure.

Boom let me know how this goes for you as I also use a Mac mini and software isn't the easiest for macs still. Would love to improve my theater with measurement as well

Even just a cheapo rat shack spl meter would be helpful. Using your ears is pointless as you'll never know whats going on.

When measuring for a room dip, do I need to count myself too??? ;D

Maybe wall reflection/cancellation? Are you using a subwoofer? I have a rear wall cancelation that no manner of EQ'ing would fix. Some makeshift room treatments improved it for me, but I still need to come up with a more esthetically pleasing solution. |

My room's about 22 x 15. Could be cancellation. I'm still hunting for some OS-X based room configuration and measurement programs.

Yes, usually audionuts are the biggest dips in any room. I've heard if you place one in each corner of the room they will suck out the dip, problem is you have to feed them.  |

If you have an iphone there are quite a few db meter apps thatbare free... Jlaudio and ultimateears to name a couple.
Rew for the mac is great, but you need a mic to run with it....some usb mics can probably do the job, dayton sell one and a few other places like minidsp have them to that work fine with rew
