I have an older K3 and a spare speaker (part #E850300). Its hard to imagine
flange being bent with little 4-40 screws, BUT, in my assembly manual p52, last
step above Figure 74,it states in BOLD lettering, "Do not tighten the screws
enough to bend the speaker flanges!"
IF this were not an issue sometime in the past, one wonders why such a warning
would be stated in bold letters? Otherwise I find the little speaker to be
as Wayne describes in his reply. Steve could you really be the first out of
so many thousands to actually bend the flanges?

Hi Steve,
Sorry to hear about this. I've never heard this complaint before (and there are
tens of thousands of these speakers in use, in both the K3 and K3S). The frame
should not bend if the correct fibre washers are used and the hardware is not
over-tightened. I'll check with our manufacturing lead to see if the wrong ones
were shipped.
I'll also check with our tech writer. Perhaps the instructions could be
clarified.
The internal speaker is certainly of high quality, so I hope you can get one
installed (I'm sure customer support will send another, given your issues). It
has excellent sensitivity (95 dB SPL, due in part to the very large shielded
magnet) and a wide frequency response range. Given the large top cover mounting
surface, the internal speaker is quite loud, with a low natural resonance point.
