JBL 2261H sensitivity spec?

[profiguy]

I'm looking for the sensitivity spec on the JBL 2261H woofer.

Anyone have this info?

2261H efficiency is 1.4% according to Harmon, can it be calculated from that?

Google says there are two of these drivers in a VTX-V20. https://www.audioheritage.org/vbulletin/attachment.php?attachmentid=73973&d=1475996902

Yes, that works, given the base sensitivity derived from TSPs.

Looks like its around 94-95 dB/2.83v
