Default 2 side-firing drivers in push/pull thoughts???

My goals are are a smaller/slimmer design for better wife approval(lets say) and putting as much LF in a single cabinet as possible.
Can you put 2 woofers crossed at say 50-70hz,ish on the side wired in a push/pull design to keep box size down yet give good bass for 2ch.I have searched and not seen any info on this type.I know all about clamshell and front to back etc. but not sure if this would work.
I can get about 9ft3 but need 3ft3 for midbass(2) and bracing,leaving around 6ft3.Most drivers will require 6ft3 for a single box for a Aura NS-18 so I was curious if this may work
Just a thought?

You can have 2 or 4 drivers in a push/pull isobaric situation for a smallish enclosure.
Google Isobaric loudspeaker and you have this interesting link

Ok, that's not a smaller box, 2 drivers -> double internal volume, unless something else that I don't get...

If size it's a limiting factor (not your wife ) you can use a better adapted woofer for small internal volumes and use one or two ""one above the other"" as you stated, that's not a problem.

You need a high WAF...

You need a good driver.
Again size it's not a problem, and isobarics with woofers pairs can be smaller in size and more expensive.

Agreed.....smaller box req either a driver with higher motor strength or Isobaric. What you propose...push pull, while reducing distortion, results in a need for a larger box. There's often confusion on the topic....isobaric is not push/pull as the air space between the drivers needs to be physically seperate from the enclosure volume.

I have 4 NS-18 and I am putting one side firing in my main cabinet and the other pair in separete floaters.I am keeping the main cabinet at 12.75 wide and it will also house 2-10" Volt and a ATC mid and a SS 7100.
