Axiom just released its latest driver, a 6.5″-woofer that was borne of an almost ground-up rebuild by engineer Andrew Welker. Â Here is his description of what changes the woofer underwent under his direction, and what you can expect to hear going forward.
Andrew Welker: Â Ian recently made anÂ announcement on the message boardsÂ about a new high-powered woofer for theÂ LFR Omnidirectional SpeakerÂ and a new model that is going to be coming out shortly called anÂ M100. Â He’s asked me to explain what went into building the new woofer. Log in

A thread on our message boards about how we test loudspeakers in production inspired a new video and plant walk-about with Andrew Welker. Â Watch as he explains how we go about testing speakers and speaker parts in production.

Â It is not simply a sweep to see if the speaker makes sound: we actually do very detailed measurements every step of the way.

Andrew Welker: Â I thought it would be quite interesting today to show you a view of either a speaker you own, if it happens to be an Axiom Product, or actually what goes into building a speaker box. Â Obviously most of the time we only see what’s going on on the outside of the speaker, not what’s inside. Log in
