Redux. It's a lot tastier than reflux. Past my review of Martin Gateley's sound|kaos Vox 3a, the Swiss auteur began to experiment with Louis Motek's LessLoss Firewall for Loudspeakers modules. Those are passive ultrasonic filters which install inline at the loudspeaker terminals to become de facto extensions of our speaker cables. Being as pleased with the results as I and Dawid Grzyb had been using them externally, Martin opted in. His clients could henceforth order his smallest speakers with these very effective modules installed inside their solid-wood cabs. Martin uses two per channel, a $1'656 layout at retail.

A pair so fitted then flew to Warsaw to be reviewed by our regular Polish correspondent. We published our syndicated outcome here. That review too ended in an award. If you want more reading material on the subject, here are two on the Vox 3f, one on Positive Feedback, the other (in German) on HifiStatement.

After his 3awf assignment, Dawid reviewed an elite €34'100/pr 2-way monitor. When asked which he'd rather have were cost no issue, he didn't hesitate to point at the Vox at 1/3rd the ask despite, for the occasion, commanding unlimited funds. Having reviewed the bigger brother to his alternate, I felt exactly the same. By November 5th, my own pair had hopped onto the flying FedEx freight train. Upon arrival, it would permanently displace Acelec's Model One as our compact new reference upstairs.

Also inbound was that system's new preamplifier with active 4th-order Linkwitz-Riley filter, an icOn Pro4 SE from Pál Nagy of the UK's Passive Preamp firm. This custom-configured Slagleformer passive with 1dB steps and remote control would give me three possible hookups for our Zu Submission subwoofer: 1/ satellites unfiltered, sub unfiltered out of the preamp to use its own 4th-order low-pass as I always had; 2/ satellites unfiltered, sub filtered out of the preamp to stack Pál's and Zu's filters for a 48dB/octave 'brickwall' effect; 3/ satellites and subwoofer filtered through the preamp's crossover for perfectly symmetrical handover, so Zu's own filter bypassed.
