This is a used Kef SP160 woofer with a SP1377 center mounted tweeter out of a Q55 speaker. Being used, it does have some minor marks and could use a little cleaning. Woofer measured 7.1 ohms, tweeter 3.1 ohms.

Good condition mid-woofer from the KEF Q55 series. May fit others as well. Part number is B160, and also has the SP1377 code next to it. The cone of each speaker is warped. The surround is intact, and the woofer plays correctly and sweeps without any rubbing or distortion. I did some research on this, and it is a common problem with this woofer and the bass woofer (also a B160, but black poly cone instead of opaque). Priced accordingly. I have 2 - the listing is for a single woofer. If you want both, select quantity 2 in the drop down menu. These are no longer made, so new old stock or used are your options. These were carefully removed and tested before and after removal. I will wrap these safely and then package in a box for safe arrival. This mid woofer has the two sets of connectors to fit the Uni-Q tweeter the model Q55 came with. The tweeter mounts in the center of this woofer.
