Which 10" drivers are used in JBL Synthesis S4S?

As the title says I am interested in knowing what drivers are used.

Perhaps a Synthesis dealer can order them as parts for you :dont-know:

EDIT: Here's a pair of those for sale woofers on Kijijji (https://www.kijiji.ca/v-haut-parleurs/ville-de-montreal/hauts-parleurs-354516-001-7115533/1266772839) in Montreal.

Thanks! I was too slow though :(

I purchased two of these sub transducers, but missed the backbox, which is about 75liters, and appears to be sealed. 88dB and -6@20Hz, high quality, but completely system engineered. Could I use these singly in a small room(not in wall), vented?

The info given here; SRS JBL Synthesis (https://www.jblsynthesis.com/productdetail/s4s.html) suggests the "BackingBox" is only about 46 Litres ( 1.63cu' ).

Info sheets say its 5.1" deep x 14" wide x 64" high.

Since the S4S is meant to be shoe-horned between a homes existing wall-studs ( with a bit of foamed isolation to prevent wall-rattles ) > those dimensions make some sense to me ( excepting the depth, which is assuming walls built out of 2x6's > which isn't really standard for inside walls ) .

Anyways, in the absence of TS parameters for these woofers your best off to place them in sealed boxes of appropriate size ( iow, the box size that JBL has used ).

Alternately, obtain the TS parameters by measuring a woofer with a DATS System (https://www.parts-express.com/dayton-audio-dats-v2-computer-based-audio-component-test-system--390-806?gclid=Cj0KCQjwyoHlBRCNARIsAFjKJ6A3mUiBlovB04ky cjr9rB60Ts_rB2zlaE19WLym4ZeYQJ-LaPyJOy8aAoGlEALw_wcB) ( or equivalent ) and then figure out the best box/driver alignment ( using something like WinISD Pro (https://www.softpedia.com/get/Multimedia/Audio/Other-AUDIO-Tools/WinISD-Pro.shtml) ).
