You could try the Sonatina Symphonic Orchestra collection http://sso.mattiaswestlund.net/, it's free, but pretty limited.

I travel around fair bit and therefore unfortunately only have a pair of headphones to mix on.

However, I've run into the issue that I can't properly hear the low end of the mix, and the bass or kick often comes out either too muddy or too loud, or too low when played at a club or live venue. I've also noticed in cars that sometimes the bass is at such a frequency that it resonates with the plastic in the car causing it to vibrate.

Just wondering the best way to get the mix to 'work' in the low-end. I've tried using reference tracks and comparing them in Ozone, but my mixes always sound more unrefined, and I've also tried pink noise mixing.


Cheers
