I got myself a Jensen RI C10R for my ProJr/Tonedog cab in late Dec. I've spent a good amount time breaking in the speaker which really opened up the bottom end and smoothed out the top end. I got to play it out at a jam yesterday and it sounded fantastic. I had my amp set on 7.5 and the tone on 4.5, with my strat on 7 I got super dynamic rythmn tones and I just turned up from there for lead tones, it sounded great. I turned on the old SD-1(set clean) for some really singing OD tones. Even with the low effiency speaker, I had plenty of volume with a second guitar player, keys, bass and drums. The Jensen speaker has a long breakin time but the difference is the most dramatic out of all speakers I've owned.
