2 woofers is necessary if you are serious about getting the most of your HT investments.

1 sub if you subscribe to the belief of “got some bass, can already.”

Woofer/ low frequencies are non-directional.
This is what dolby website says.

I was thinking necessary or suitable for 1 or 2 depends on the room size.
Need to be very careful of too much low frequencies in a small room.... that's how you get bass boom and all the sounds become muddy.

Yes... Low frequencies can be... non directional.......until recently proven otherwise.
The sub for the back or surround channel is just to handle whatever lows encoded in these channels where the speakers used cannot handle well... act as supporting role or as handling role.

Agree with Jag and other bros here on having 2 subs! :)

I used to be in 1 sub setup for some time. Reknown sub brand. Though bass was enough, but it just lacked something. One problem I experienced was easy to localise the bass in certain scenes even with proper calibration. And the body tactile was not ideal. Plus I had wide band bass dips, so certain scenes Im missing certain bass Freq effect.

Adding a 2nd sub in a different location in my room with proper placement and bass calibration made a day and night difference.

First it smooth out the Freq and fill up bass dips. So I get most of the full spectrum of the intended bass and not have missing big pockets of bass due to major dips.

Secondly, the 2nd sub gives me a "3D effect inmersion of bass" where bass just moves like surround sound in the listening area and the bass hard to localise.  1 sub can't achieve this no matter how much I calibrate it .

Next, thru an additional sub, I am able to play with near field placement to get the tactile body effect (referring to sharp chest thump n layered low rumble) I need on my body, without having localisation issues

Without good placement and calibration, 2 subs could sound worse, which u pointed up muddy. IMO, muddy bass usually is not due to having dual subs. But likely due to the lack of good calibration and/or placement, and also the vibrating factors in the room.

I feel that u will benefit from dual subs regardless of room size, with proper placement and calibration.

And I suggest dual identical subs for easier calibration n integration

Bass is one of the most impt elements in HT. Place them well, calibrate it to your best u can and it will bring u a very big smile in your HT!

Hope this helps! ;)

+1 ... same experienced with sevenz

Muddy bass indicated that ur rooms response has deep dips... no 3D bass layers at all

Boomy bass (echoing) indicated that you have standing bass (peaks)

Watch movie... 'the nun' ... a lot of low freq deep bass and good active surr effects.
Good to test ur subs.

One is a must.
Two for balance.
Three I know you going to do something...
Four I don't know what I am doing..... till I do it.
If we talk of low freq it cover till 200Hz or something like that for most of the AVR....
When we talk of subsonic is down from say 50hz to I don't know how low most avr can goes....
when we can detect where the Bass come from or ppl refer to directional , it have much to do with room/placement/ corner loading/gain , as such can tell where the bass freq come from not just low or mid low freq .Boomy is a term refer to that sound Q of the sub not refer to directional .
We are not second hand dealer , all items we sell as used are tradedin from our customer and we don't rate it condition but for the buyer to decide on it own.
From time to time we may sell off some New but open up used for rental/standby/loan items and to ensure they cant be sold as Brand new , we will dispose off the box.

So 2 woofers it is.
Now what about placement?
1 front and 1 back or 2 front left and right?
Is it ok to have things in front of the subs?
I see some people have couch in front of the subs etc.

1 front and 1 back or 2 front left and right? IMO, I would recommend the former. How much flexibility in placement do you have? ie. can u place the subs anywhere and are there aesthetic concerns?

Is it ok to have things in front of the subs? preferably, not. A clear path to the MLP is preferred.

I see some people have couch in front of the subs etc. do you mean, placing subs behind their couch?

Now comes a twist on the question.
1 big sub or 2 smaller subs?
