My experience may not be very relevant since my Druids are somewhat modified. Anyway, I have had great success using two JL Fathom f110 with my Druids. Features such as inbuilt auto dsp, phase, and roll-off options provided by these subs makes it fairly easy to achieve good integration. I use two because I am a bass-freak but one should be adequate and can be acquired used at your budget.
Subwoofer for "seamless" integration with Zu Druid
I've had a pair of Zu Druid Mk-iv's for about 3 months now. I'm really digging them, but miss the lower octaves. I don't know much about subwoofer design or manufacturers. Anything that would give me solid response down to 30hz (or even lower without sacrificing speed) but still be fast and tight.
What is the best design for integrating into speakers such as the Zu's (sealed, ported, with passive driver, etc.) and what brands/models should I be looking at? I'd like to spend no more than $1,000.
The REL's are reviewed well, and the Zu Method and Mini Method seem an obvious choice, but aren't manufactured anymore and are scarce on audiogon.
