I never thought I would find happiness with a sub-woofer working with the Apogee Divas, but a Muse 18 using the Diva "personality card" brings the Divas alive. Integration is spot on. The Muse company still makes the custom cards available for a wide range of speakers even though the sub is discontinued. The 18 provides three adjustments; level, dampening and delay. The latter allows exact integration with the satellite speakers. Hmm, seems odd to call the Divas satellites.
Cheers,
