Axiom Home Page Forums General Discussion Stereo Bass reduction when sitting down

Hi Paul, I was thinking that maybe I should build a "riser" just to get some kind of air space between my seat and the concrete ?

More questions. What happens if you move side to side or move your head up and down at the love seat location.

Nulls can happen in any of the three directions in your room. That the bass returns with subs suggests its a null of some sort. Have you tried changing the location of your speakers at all?

I have a big la-z-boy, probably with cheap leather, that is beside my SW. It has a high back and lots of padding. When I sit in it, I hear the bass just fine, so I doubt it's your chair.

Mine is also a Lay-Z-Boy loveseat / recliner. Not sure why this is happening..

Hi Fred,

When I am sitting in the left seat, and move my head left, some same height, but basicaly my head is not leaning on the back of the chair, I hear way more bass. My butt is in the chair but my head is left of the seat back and the bass is there !.. it's the weird "chair back effect" LOL

I might switch the entire room around and see what effect that has..my seating position has walls on both sides while the speaker (and tv) side, the right speaker is 30" from the side wall, but the left speaker is 10 feet from the wall because of the room config.

So, if you shift the seat left as well, does that reduce the bass. If it does, that suggests the seat is part of the issue. If not, its a null related to room width.

I will try that tomorrow...as the child is now in bed and I have to be all quiet like :-)

Thanks for all the input everyone.. you made me think of things I had not considered.. that's what I love about this place !!

Cheers
Steph

So, to fix a null you can what ?

1. Alter the room physically ? by adding a wall etc.. ?
2. Try to get the seating position out of the null ? which could be very hard to do, since the "best" spot in my room seems to be 2 feet from the TV !!not the 10.5 feet I am sitting at.

3. Moving the speakers ? but if the speakers are not in a null or a peak and sounds great were they are and it's the listening position that is in the null, how does moving the speakers going to help ?

4. Other sugestions ?

I should also clarify, that when I use the subs, I "feel" more bass but that does not necessarily mean that I hear more bass per say. I just wanted to clarify my earlier statement that with subs I got " the bass back" which is not really accurate. I feel more bass, but it's subwoofer generated bass that does not sound like it's from the main front speakers even if calibrated. I know that I am probably just being too picky..but I just want to understand why it sounds great when standing up and sounds completely different and not in a good way, when I'm sitting down .. it's so frigging weird..

Stay standing while listening in 2ch.

Fred covered why this is happening in an earlier post

"Nulls can happen in any of the three directions in your room."

Nulls are created by the dimensions of the room and the frequency that corresponds to these dimensions are either enhanced or cancelled.

With the subs on you are feeling more bass because they can play all the lower end louder than you can get out of your speakers, but as you suspect you are most likely still not hearing the sound that is part of the null. I think if it was my room, I would just use my subs as I think the only way around this will get to be very expensive(room modifcations) and time consuming.
