They were referred to subwoofers in the past - could that comment be a legacy reference to the last generation of Utopia's?
One of the reasons I prefer Focal is the in house development of their components. I'd just like to get confirmation of my interpretation of your post in regards to the 1028be tweeter specifically and confirm the 100 max break in. I've got the specific question out to one of the Focal engineers I've been in contact with before and will post the response when it arrives.
Well, they do have a true Sub Woofer that also uses the EM technology. in the previous Be series, The Grand Utopia's Be 16in driver I think was called a Sub Woofer but they simply call it a woofer on their site now. The EM "woofer" is powered by its own power supply that allows you to fine tune how much Tesla force is put out. Also, see the following link.http://www.grande-utopia-em.com/en/technologies/em.php
As far as the cross over and how it potential breaks in, here is the reply I got. Remember, you asked for this
Understandably odd concept to wrap your head around.
When you pass an electrical signal (Current) through any conductive materials (Usually metals), electrons pass the energy from one metallic crystal to the next one. Each crystal has a "Wall" that defines the physical size, shape of the crystal. These walls need to be "Climbed over" (Not really - more like passed through), or in automotive terms, these "Walls" are like toll booths on an interstate - you need to slow down, pass through the boot area, and then accelerate again.
Remember - we want theoretical unlimited instantaneous speed from the moment we decode the musical signal from our source, to the moment we deliver the amplified signal via the amplifier, and instantaneous movement of the drivers (Why we place so much importance on low mass in driver technology - faster (Shorter time) acceleration (Transference) of energy to your ears, which you interpret as music.
ANYTHING that slows this time based energy decoding / transfer / amplification / driver movement down will be "Heard" as a loss of information, or a mixing together of information that was discrete and separate from other moments of energy that we saved (Recorded for later playback).
So if you've followed me so far; when these energy waves travel from crystal wall to crystal wall bombarding the metal crystals that make up solder , PCB boards, resistors, capacitors, speaker wire, interconnect cable (AND Digital packet transfer, even though we're sending binary numbers, NOT analog wave patterns - we call these slowdowns in movement "Jitter Error"), some of these walls end up have "Channels" (Weaker spots electrons can travel through quicker than other stronger places along that same boundary wall) that let energy waves (Actually NOT waves at all - energy being passed like a fire fighters bucket chain with people passing buckets of energy from one person to the next, rather than one person walking the length of the line (Cable)) travel with less resistance. Less resistance, faster travel, less time based errors, less mixing up of older and newer energy information that we hear as loss of details, sound stage, etc. Think of our toll road analogy - each crystal boundary is like the toll - cars with electronic dashboard passes can drive through the toll and NOT stop; cars that need to take a paper toll card have to come to a stop and take the ticket - that car arrives at their destination after the car that had the electronic dashboard pass.
So - with that concept understood, over time, after millions of energy waves bombard each of these metal boundary crystals, a path of lower resistance (Easier, faster passing) is formed. Speed increases, music opens up, low level detail is better heard/felt and our music systems sound more "Real". Turn a system off, leave it for a few months and the process has to start over again since metal crystals are NEVER at full rest. They shift and contract even though they look "Hard" to us, they are fluid to some tiny degree.
So there you go
