I want to share this:
I have re-watched the video by Jude and I somehow do not understand the brilliance of the innovation and the genius of Shure's R&D dept.
It seems the SE846 is based on the SE535, developed as a result that the competition stuffs four drivers into the same housing and thus sells better. So Shure added an additional bass driver but noticed it muddies up the frequencies. To free the additional driver of mids and highs, a four inch intestinal was included, so only bass comes through.
Shure then realized the longer sonic distance lifts the sub-bass further off from the music. This feature is sold as a revolutionary subwoofer and costs 500 $.
Is this correct? Or where is the error in my train of thought?
Official reply by Shure:
"Is this correct? Or where is the error in my train of thought?"
Actually correct! The advantage - or uniqueness: two pure subwoofers are being used. Other IEM bass drivers use bass/mid drivers.
The use of low-pass achieves clean and dry lows - like I have not yet heard in our own in-ears.
Why do you raise concerns about the temporal delay? We are talking about frequencies below 75 Hz. If it should really be 10cm (I cannot verify this number in my documents), then I'd expect a phase angle of ca. 8° or 0,3 ms.

1. While Shure claims that other companies use bass/mid drivers, this is fairly generalized because I can think of some right now (universal and custom) that do not.
2. I read very little improvement over the SE535 except for two subwoofers. The main concerns of the SE535 were rolled-off treble, fatiguing mids and very limited soundstage.
3. The delayed bass is supposed to be unnoticeable. That might actually be very true. However, I'd expect an unhealthy dose of rumble.
4. Did Shure just confirm that they charge 500$ for the subwoofer feature?
It's nice to see Shure commented. I am still curious about the product but I am almost absolutely sure they will not please me as I listen to a lot of Classical, Jazz and Vocal.
I just wanted to share. Have a nice day!
