So, a technical question I was thinking about.
I'm no engineer but as I understand it that 'plate maze' for the sound essentially routes the low frequency sounds through a very long channel, and because higher frequencies do not bend around objects as well they just end up 'lost in the maze' so to speak.
I'm wondering what advantage this mechanical filter has over trying to achieve the same kind of roll-off with the crossover electronics?
Also a bass tube with a curve on it - is that the same principle as found in the JVC FX100 / 200?
The high frequencies are passed straight through, rather than bending like bass. Shure are well aware of the technical details. From what I understand, Shure chose a mechanical routing low pass filter because it exerts less collateral effect on the rest of the frequency spectrum, at least vs. crossovers. At this point, no one can say for sure, but the low pass filter is an elegant, if expensive, method. And, it works. I am looking forward to more impressions.
