Hi ! the simple minds like mine love myths
In the photo below one of my old myths
But looking at them better an expert eye can notice a rather questionable design choice
I say this after reading that in fact that choice has caused problems in the practical use of the speakers
Can any of you identify it?

I can see a few things I might have done differently myself, but in fairness I'll wait until it is revealed.
It's a terrible design by the looks of it - why so many tweeters and are those vertical ones tweeters or mid?
Hi 🙂 no I could give a hint
a speaker this big is clearly designed for big rooms to be filled with a decent sound pressure full range
a design mistake can cause the speaker to break down in some weak points
8 ribbons 6 tweeters and just one weak midrange with a paper coil former ?
a death foretold
and actually there are stories of midranges broken when the speakers were pushed a little

could be But i see it used alone also in other smaller speakers from the same brand
one things is sure They really liked it
It should be a Philips ad5060/w8 probably also used in the dq10
it covers from 200 to 600Hz
the fact that is used in such high end speakers has put it on my radar
and also made me think that even good but not particularly expensive parts can provide great sound when used correctly
but its small size coil and a paper former make it not suited to tolerate high power levels
they could have used more in parallel on the side of the tweeters
in the dq10 is cut at around 400Hz by the way

Thanks a lot for the valuable advice However there could have been an easy fix doubling or triplying the driver or changing the driver for a more robust one
If i had these speakers i would immediately look for a replacement
becuase even if it does not break under pressure it could distort a lot
to provide 200Hz at lets say 110dB/1meter with 1% distortion a robust 8" is a minimum I guess
the domes and the ribbons i guess are up to the task easily The woofer i do not know
Yes they are magnificient But almost anything can be improved
I see a startling difference in size between the big woofer and the tiny midwoofer
I am sure some distortion measurements at 100dB would show some peaks in the Philips range

Might, but I guess a lot of research and engineering would need to be done.
And... they would lose their value. 🙂
Thanks a lot weird choice i do not understand the reason and the working principle
i just notice that is more an exception than a rule i do not see almost any woofers around with dual coil these days
I think that the very strong point of Infinity speakers has been the look after all They are very beautiful products
But i would like to see more measurements
Google DVC (dual voice coil)

All the above is true, but dual voice coil woofers are used for different reason. The two coils are connected to different taps of the crossover, and this way +3 dB can be added below a certain frequency, where the second voice coil steps in. It is used for extending the low region.
They can. Part of my response was that it isn't being used over a wide enough band to evaluate it's breakup performance. Sometimes when used with a limited crossover, this will be on show.
