7040 APM : Surprisingly powerful

As expected this sub works excellently with 8010A and 8020B.

Nicely controlled, very clean, well balanced and more powerful than its specs would suggest.

The super broad range of sensitivity control and internal high pass filter mean it works well with all manner of non-Genelec powered monitors. Just order the correct cables because connections are XLR only.

I was surprised how much the sub adds with somewhat larger speakers such as Mackie HR624Mk2, provided you accept the sub's power limitations.

Auto-power off/on works well.

DIP-based adjustments are adequate and easy to configure, but not something you'd want to fiddle with every day because of their location.

The setup is used for critical listening to music rather than movie/nightclub use. This sub won't loosen your teeth, but provides precision bass reinforcement for smaller boxed speakers.
