Eight inch Weber 8F150, ceramic magnet, 8ohms, 25 watts. I had this in an old Valco amp and it was killer. Excellent condition and already broken in.

From Weber website:

For replacement of vintage Chicago Jensen P8R, P8Q, C8R, and other 8″ applications where a lot more low end and overall punch is desired.

8″, 30oz Ceramic magnet, 25 watts, 1-1/2″ voice coil, ribbed cone. Big, strong, well controlled low end. Detailed, later breakup. Very loud and aggressive with a lot of punch and dynamics for an 8″ speaker.

Will not fit in tweed, or early BF Champs, (but WILL fit in Weber and Mojo 5F1 cabs) – The narrow basket will fit into 70’s SF Champs, and might fit in other tight-fitting combo amps – some amps can be tricky.
