Picked up a sa t of these at a church sale the other day for $2 a piece. My first ever real score! They had a plastic toy dinosaur inside for $1 more haha one of the smaller woofers is cooked but I already have a replacement on the way.

Congratulations! You can fix the woofer pretty easily. I'd suggest epoxying all the good ones so they don't shift as well.

Those missing tweeter mounting screws will cause air leaks, which affect the bass response.

How should I do that?

They were done today lol thank you for looking out!

How should I do that?

Remove the drivers and apply either Loctite Power Grab or JB Weld around the magnet plates, top and bottom.

Cool thank you

How should I do that?

Remove the drivers and apply a 2-part epoxy around the shoulders on the top and bottom of the magnet. Apply it evenly around the circumference and let it cure completely before going back in.

Edit: These'll work too!

Loctite Power Grab or JB Weld

I'm now using these on the B channel with my newly acquired Cornwalls on the A channel. Each on their own seem lacking in one way or another to me. The Cornwall are missing the higher end clarity I like and the M12 the depth. Together however, my house sounds like heaven!
