How to "spread" bass?

In my room I have only one place a sub which is in the center of a wall. Being used for music only, I want to figure out how I can distribute the bass evenly from only one cabinet. I was thinking maybe daul opposed with the port facing forward has the best chance. What do you guys think? Also thinking of going with 2 18s like the HO or UM from Dayton.

Forgot to mention that it's not dead center and I have a few feet of wiggle room.

You will need more than one source of bass in order to "spread the bass around".

You will need more than one subwoofer.

Placed ideally the results can be OK, but with only one sub room mode sourced response humps and boundary reflection cancellation nulls will always be there. Two 18s in one cab will both excite the same modes and nulls. Put them in two cabs, and remove the phrase 'I can't' from your vocabulary. If size is an issue go with twelves or fifteens. Smoother response trumps higher output.

From what I gather, dual opposed is a sealed implementation and doesn't utilize ports. Will you elaborate? I'm just curious.

Dual opposed is an orientation and not exclusive to sealed.

It is possible to have dual opposed orientation in any alignment.

The M.A.U.L. for example, is dual opposed with four drivers and it is a vented/bandpass alignment. Not sealed.

As is the new Skorn on Data-Bass.

Learned something new today. Thanks for clearing that up Scott.

Subs have been known to be seen lurking about, surreptitiously and beautifully disguised as end tables , coffee tables.

a rather well executed example would be an end table from @squire s007

also, and maybe even better for "just" music, the BFM Table Tuba

give them a look

Yes sir I have an "end table" sub rite beside my easy chair, d.i. Y. Made by myself. 2.6 cubes net. Tuned to 38 Hz. 15" kicker driver. Works pretty well, but drops off about 34 Hz. Wanted to add a lil decoration so I went with a small engraved logo. It was a fun build.

Bass is best spread with a large butterknife.

AS far as the woofers go....... the RSS460 is the choice for JUST MUSIC. It has much more finesse than the UM18. The UM18 is better suited for HT duty.

I have 2 RSS460 in full Marty cabs....... Awesome sauce.

The simple key is bigger is not better with what you want
You want consistency, put another sub in the back wall in the middle and you will likely be thrilled at the result.

You might have to implement 8 8's, the bigger the better...

4 dual-opposed 8's, one in each corner or wall.

One sub (of any size) won't smooth bass over a wide area. Only one seat, if lucky...
