With a Deluxe Reverb's power rated at 22W, and this speaker being rated at 25W, it is possible to use, but we also encourage you to consider going with a speaker that is around double the amp's wattage, such as the P12N. https://www.amplifiedparts.com/products/speaker-jensen-vintage-12-alnico-p12n-50-watts-no-bell
