new subwoofer help

[giggsy1977]

Rooms have peaks and nulls. Square rooms are notoriously difficult for home cinema sound.

I would play some music with strong bass that you familiar with and sit where you normally would. If the bass is weak of overbearing, move the sub to a different location and try again. The 'subwoofer crawl' works similarly in that the sub is placed in the main listening position, music played and you crawl around the room until the bass sounds best, then mark that spot and put the sub there.

Then run Audessey on the Denon (sub volume at - 10 to - 15) and see what dB the Denon sets the sub to (something around -5db would be a good result). That gives you some headroom if you wanted to turn it up.

Well, that could be a number of possibilities…the woofer may be out of phase with your main speakers. Try the setting for that purpose. (When you’re right in front of the sub, you hear its direct output, not how it reacts with the room)

Or the woofer might be better in a different position, or your chair is in a ‘dip’ due to your room dimensions, versus the wavelength of the notes you’re missing.

Just experiment - you can’t break anything. Move the speakers a bit at a time while playing bass rich music, preferably with you seated and a friend/partner doing the moving.

hi i did sub crawl and put the sub there but deep bass is good now but mid level is missing. also in stereo mode 2.1 music it feels bass is late delay can you help? denon x4800h

I’m afraid that’s rather beyond what I can do from behind a keyboard, other than suggest trying midway between where you have it now and where it was originally.

Have you tried the SVS app? You can tweak frequencies up and down.

Every room interacts differently to bass. The lower frequencies have a long wavelength so bounce all over the place.

You can alter the phase in 1 degree increments so that could be a place for starting?

tried phase slowly from o to 180 felt no difference

IMHO never used a Sub in a small room
Google room Nodes/Null/Standing waves , Deep bass you need a large room
Ideally for sub sonics under 20hz you need a 80/100feet room with multiple ( 2/4/8 Subs )
40 Hz wavelength of 8.58 meters/28.15 feet
20 Hz wavelength of 17.16 meters/56.3 feet.
