have you tried the TEBM46C20N-4B ?
I'm planning a 2.2 portable bluetooth speaker and want to use 2x Sonos Play 5 Woofers and 2 BMR drivers. I was looking at the CSS BMR56XE N8R but it seems not possible to buy some.

TheTEBM65C20F-8can not be used full range. And while the data for TEBM46C20N-4B looks good, i have read here on diyaudio that the speaker has some problems after some time, and the frequency response alters with time.

I also have thought about using 2x Tectonic TEBM35C10-4 for each side.

It would be kind if you would share your thoughts on which driver would be the best.

Thanks

Unfortunately I do not know the TSP parameters for Sonos Play 5 Woofer, but to make the right choice you should take into account the difference in power and sensitivity. Therefore, I assume that most likely you should choose the TEBM46C20N-4B. By the way, I have no negative experience with these drivers.

Thank You

i'll try to get some more reviews about the TEBM46C20N-4B

and yeah its hard to get any data for the woofer as it is not sold separately from sonos, but you can get it on ebay. the only "data" i have is that the "Xmax is 9.4mm each way" and a very low distortion.

The Sonos Play 5 (2nd Gen) has 3x the 4" Woofer and some DSP magic with which the Speaker goes <40Hz in such small enclosure. It should be one of the best portable speakers you can buy, but i have not heard it myself yet

this channel has some content about it, since its rare to find any info about Sonos speaker parts. i guess the people who buy Sonos don't really take them apart xD
