Yes, by all means, try All Small with Mono Sub.

And set the crossover a little above 35Hz (Minimum). The 35Hz Spec is usually after the speaker is starting to drop off and is fully capable somewhere above that spec. My speakers are also 35hz and I set the Cross Over to 40Hz. Since you can't set crossover per speaker you need to set it above the smallest speaker.

It's really a good idea to get comfortable with something like REW Software because you need to get the Phase/Distance correct because different subs have different delays through them and your distance value you set in preamp can be completely wrong. If it's all Meridian Speakers it's not a problem. But with anything non Meridian you have to sort it out yourself. And it's not easy.

I leave the LFE Crossover value at Default.

Yes, any channel can have low frequencies on it (Movies or Music).

- Fiddler (IMHO)

If you think listening to music is fun, try learning an instrument.
