This is one solution. But there is ARC, Trinnov, Audyssey and Velodyne auto EQ as well.

I personally own processors with ARC, Trinnov, and Ausyssey Pro, and I think they are the best solutions out there as far as getting the speakers to place nice with the room.

I thought this was a bad approach to the problem, but if you say they work I trust you, what is the best one and how it works? Eq? of corse it has to use a good mic to know whats going on...

I agree - a system that rolls off above 40 or 50Hz would have no high end at all!

Honestly tho, a system that can do a real, clean, solid 40Hz can certainly be a high quality system. Even at 40Hz you'll get plenty of low end and you'll even feel room effects from the recording venue - with a good amp. The rest of the system has to be good, of course.

The microphones that come with each processor is designed specifically for the characteristics of that processor. They are factory calibrated, and they can send you the calibration files so you can do it yourself as well.

Personally I think ARC and Audyssey are best for me, but all three as a whole are equally good and excel at different things. All three are equally good at flattening the frequency response at the "sweet" spot, and are equally good at getting at least 85% as good results at the seats around and behind that spot. None of them are good with handling model ringing, and that is why I recommend using passive treatments along with them. All of these auto EQ seem to perform better when passive treatments and ideal placement is taken into consideration.

ARC and Audyssey pro are PC based systems, so you can see the processing at work in real time. Trinnov has a nifty feature that allows you to resposition your speakers if they cannot by physically aligned ideally to industry standards.

All of these system are better than analog EQ, have far more analyzing resolution, and FAR more filters to fix acoustical issues.

Lastly, none of these auto EQ systems can look as deep into speaker/room interaction than Sim3 analyzer. It can do very complicated speaker measurements, and none of these processors can. Using them together however allows you to accomplish amazing and profound acoustical analysis and correction on your system.

I use 4 AE IB15s in push pull slot load IB with a crest CA12 amp. On three occasions someone had to leave the room to use the bathroom. HAHA

just to clarify my original post re going to low

no one bothered to ask what i meant by too low !!!
in my systems i always go for around the 30hz point as my cut off as below this point the room becomes the limiting factor and i dont like the sound of vibrating walls,car panels and such

i dont feel i,m missing anything by setting my cut off here and untill i hear a system that goes lower than this without the window shake and wall/house vibrations that go along with it i wont change my mind

i dont think low bass is rubbish just the sound of vibrating windows and doors/walls

Your posts seemed to equate the two. They don't have to be the same, of course.

Yes, it's a problem. A lot of things in the house start to shake with high levels of low bass!
