Default Minuature Low Pass Filter

Hey wise ones

I'm building a portable speaker and i'm trying to cram it into the smallest space i can. It has a sub and needs a low pass filter feed it.

So far i've build a simple active filter off a lm358. The size came to 10mm x 40mm x 8mm ( w l h ) It's small but it's by far the biggest component. Bigger than my bluetooth module and amplifier. It's height is the main problem as i'm using hole mounted components. I could switch to SMCs but it looks fiddly ( i struggle with matrix board!)

Any suggestions on how to make it smaller.

Audio quality for the sub is not a concern here.
Power supply is up to 12v
Mono bass is ok
Max height is 5mm
