Druid EFX is a high efficiency, high output, direct radiating wall mount or bookshelf loudspeaker designed for high fidelity home audio, office, and home theater use. It is a crossoverless, full-range single driver loudspeaker, complimented by a high output super-tweeter. They excel in dynamic realism, and are fully capable of recreating timing, tone, texture and natural stereophonic sound despite their space and size friendly design. The main design intent of the Druid EFX is as the name implies for the effects channels in a multi channel system.
Druid EFX ship complete with the innovative May Audio Smarter Speaker Support for mounting, as shown in the photo.

All the Zu Druid series loudspeakers, including the Druid EFX, are a high efficiency design that also present a very friendly 12 Ohm load to the amplifier. Because of these two features, users are able to explore a whole new world of amplifier possibilities. Users of low powered amplifiers including vacuum tube single ended triod designs will have no problem mating with and driving Druid series loudspeakers to very respectable levels. And since all the Druid loudspeakers are given high power capacity, those who really want to light up the house just need to match a solid 30 Watt or better.
And one more point on the Druid virtues, one that cannot be overlooked by the majority of people and families enjoying music and movies in their home... those of us on a tight budget who would prefer to roll their hard earned money into the defining component, the loudspeakers, instead of obsolete within ten years electronics, can rest easy knowing that inexpensive solid-state receivers inherently sound better on the easy 12 Ohm load. Combine the fidelity improvement of easy loading of the receiver with the power and glory of Druids and honestly, the sound will totally amaze you. This lets you get the right loudspeakers in your room, get a real boost in enjoyment, and let you easily upgrade electronics when you’re ready.
Druid EFX Mk4 vs Druid EFX Mk4/08 changes and features
Super-tweeter changes• Complete remanufacture of tweeter driver with the removal of all shims, gaskets and screws.
• Ferro-fluid is removed from voicecoil gap.
• Polyurethane bonding and the removal of all voids and shims on tweeter top-plate waveguide / voicecoil frame.
• Complete bonding of composite phenolic dome diaphragm suspension to driver top-plate.
• Repositioned / enhanced voicecoil / gap alignment.
• Dynamic alignment process of voicecoil and gap to ensure correct tone and shove (pre PU adhesive set).
• Reflow voicecoil lead-in pots with high quality lead-free silver bearing solder (RoHS).
• 0.5% or better matching for quality of tone and efficiency.
• 160 hours minimum factory burn-in post network termination.
Super-tweeter high pass network changes
• Simple two component (Cs + Rs) network.
• Kimber Kap 1.0 uF now featured in place of the Solen based network.
• New top performing Mills resistor with revised values.
• Reduction of termination joints by two-thirds.
• Direct connection of capacitor, resistor, FastOn, via cold-forged and sealed termination.
• FastOn terminals are now terminated using the solderless Amp crimping process.
• Dramatic reduction of solder joints. In fact, the voicecoil lead-in pots are all that remain.
• 0.1% matching.
Full-range driver changes
• Improvement in cone and cone binders.
• Improved assembly tolerance.
• 0.5% or better matched pairs.
• 160 hours minimum factory burn-in, as we’ve been doing, but this time we kit and batch them to burn-in with the matched super-tweeter assembly. Also using some new music James selected for good, well rounded, musical appreciation.
Changes are the direct result of lessons learned with the research and engineering of our Zu / Denon phono pickup, like removing all possible voids and removing or controlling resonance on plates, we’ve created a dramatically improved tweeter. All the above listed tweeter changes reduce resonance by more than 30dB comparatively and spread the Q by an octave; together changes also yield very tight batch tolerances—80% of the batch measuring within 2%.
There are not a lot of changes to the full-range drivers, the majority of the improvements can be attributed to refined processes, batching, testing, matching, and QC to ensure identical sound between channels. These changes were not possible when we were doing small runs. Now that we are batching 100 units at a time, or greater, we are able to hit these pretty fantastic tolerances. We have also improved the binders used in the paper cone and now have about as consistent a product as can be had.
Druid EFX Mk4/08 loudspeakers also feature CNC machined from billet Alcoa 6061 super-tweeter lenses. Alcoa 6061 billet aluminum driver reinforcing 1/4” deep trim rings. Machined from billet aluminum binding post plates, machined serial numbers, machined driver motor components and input lugs. Other features include our Zu B3 silver alloy internal cabling, cold forged terminations for the highest possible conductance and fidelity between interconnecting terminals; CNC machined cabinets featuring an MDF core and composite shell; and the highest quality finish and finish tolerance in the business. One look, or listen to a pair of Druid loudspeakers will convince you that they are without question a world-class product made with the highest possible care—learning that they can be yours for a very approachable price is flat out bitchin.
Manufactured by us in Ogden, Utah—USA. Like everything we do.
