Fender 65 Twin Reverb RI replacement speakers ?

i am looking for what you would consider the best replacment/upgraded speakers for my 65 twin RI would be. i am looking for a speaker that is a little more open and warm but will still maintain the chime and sparkle. the amp is great but is as im sure you know it is extreamly load and doesn't really open up till the volume is on 5 which is to load for some venues. so i would like a speaker that will also alow me to push the amp a little harder with out blowing peoples heads off. the stock jbls have started to sound better as i'v broken them in but i can still hit these highs that will just make ears bleed.

Thanks for any guidance you can offer.
