new subwoofer help

[Yelamanchili manohar]

Will there be massive difference between REW and dirac live if i buy dirac?

No room correction system can fill the dips / cancellations. The only solution is to change your speaker + subwofer position or change the position of your listening chair or change the room . Iam afraid no DSP can help here.

Nice u bought umik 1. Ho much did u buy for?
I had the same problem of bass lack (even now it would be there), but now after i shifted woofer right behind me, its cool!
How big is your room? Is it open to a bigger space of some kind or closed?
Nice to know that you are now using those frequency loops!!.
Remember, now that your ears are tuned to subwoofer, you will never be satisfied with full range speaker. Try yourself and let know here.
Caz, i had the same notion. Now i can never be satisfied with my pioneer bass..The itch for more will keep growing...
There is a app called spectroid in android. And there is a youtube video called frquency sweep. Does it ring a bell??!!
ENJOY THE FUNNN!!

I have finally set my denon x4800h to LFE only and speaker crossed at 80hz i have no issues now. Music also have good bass now . I yesterday turned on paramatic eq on svs app it was like boom while the music was already playing. I have just got room eq wizard full book printed just got it. I will study this software fully now. It will atleast tell me where are the peaks and nulls and can also help with speaker and subwoofer timing match and all that. i have got dirac live manual printed will study that asll well.

In my limited experimentation with a small Qacousitcs 8 inch subwoofer, in 3 different rooms. I always ended up with the subwoofer placed right next to my sofa. It is easier to get a smoother bass response closer to the subwoofer than far away from it. So if you have the place, then place the subwoofer closer to your seat, as the AVR can delay the subwoofer to time align with the front and surrounding speakers.

Only in 2 channel systems we try to place subwoofer closer to the main speakers, so that both main speakers and subwoofer are approximately same distance from listening position. As 2 channel amps dont have any time delays or phase correction.

Edit -If placement next to seating position is not possible, then the next best location is in a corner, with the sub woofer placed as close as possible to the walls. The shorter the distance from the walls, the higher in frequency will be the bass cancellation in frequency. By getting this distance small, the frequency of cancellation will be way beyond the frequency the subwoofer is operating in. This will remove SBIR induced cancellation, but there will still be room induced peaks and troughs which have to be dealt via audyssey. Please read the below article for a detailed explanation :

Iam aware that Iam suggesting two different places to try the subwoofer. As this is the only way to experiment to find out which works best in your room, and at your seating position. However, if you want to remove the guess work and do it more sceintifically, then try the below

Edit 2 - REW is free for a PC. In REW there is a free room simulator. You can measure the dimensions of your room, and enter them in this calcuator, with the location of your speakers, the subwoofer and your listening positon. This is a very simple and extremely easy to use calculator. And as you move the speakers and subwoofer, the calculator will show the frequency response at your seated position. So without having to do sub-crawls etc...one can find the optimum position for thier speakers and subwoofers for the best possible frequency response. Below is a youtube link to the same. All the best

yes i just got REW manual printed i will study it fully. you are right 1 week ago i put my sub just to right of my chair it was very deep bass. but i dont want to put it there.
