Sounds good, hard to beat that combination.
I had a MusicMan 130 wat head and a 1-15" folded horn at one point, made a sweet sounding bass rig.
I've also had a couple of the RD50 amps, a 1-10" that I stuffed a 12" into, it was scary loud for it's size. I played a lot of gigs with that one.
Later on I had the RD50 1-12, Chet Atkins used one for many years through the end of his career/life.
As for the EV speakers, I had a couple different rigs with those, starting with a pair of vintage Fender Champ chassis with consecutive serial numbers running stereo into a 2-12" cab with a pair of EVs. That sounded awesome if you just dimed everything and hit it with a Les Paul. Eventually I got a Mesa Mik III head and ran a Vox 4-12" cab iwth the same pair of EVs and a pair of JBL D120s. That was WAY TOO LOUD and I have the hearing damage to prove it!!!!!!
Just mos\tly using a Roland Cube 40gx now and it is more than I really need. Sometimes I tote a Boss Katana 100 Combo set to 1/2 watt instead. One gets tired of lugging heavy gear, no matter how good it may sound.
