I have owned and used so much gear, that I actually sometimes forget that I had a particular piece of gear!
I've owned many 4-10 cabs, and a lot of bass speaker cabinets. SVT's Sunn, Sunn and Cerwin Vega folded horns- Bill Fitzmaurice, Schroeder, Mesa, Epifani EA, Carvin BRX- I still have them. My last count was 10 in my inventory. So, what does this 70 year old 50 year super critical pro bassist use right now? Most of my gigs are in small venues- casinos, or clubs, where a decent amount of volume is needed, but there is no need for any large bass cab, including a 4-10. I take one of my Carvin BRX 10.2's. I have two. One has the very first 300 watt Eminence neos in it. The other had the later Chinese drivers- which I removed, and put in two Avatar Eminence neos with longer X-max. If I DO need a 4-10, I'll take both. Those Carvin cabs are really killer- 44 pounds- a bit heavy for neos, but those Eminence neo magnets weren't really featherweights. My now sold EA VL-210 was 74 pounds, and didn't sound nearly as good to me as the BRX cabs. These Carvins, are absolutely the best bass cabs they ever made. A lot better than their old redline stuff. I believe that two cabs stacked especially vertically, makes the bass clearer, both to the player, and to the band- and to the audience. A 4-10, onstage, will be below the level where you can really hear it. THAT, is the same issue those of us who play upright face- you cannot hear the actual pitch of your bass, unless it is amplified into a small amp- or monitor at ear level. You just cannot really hear what your sound, or volume in the room is.
I often use my Genz Benz Shuttle 9.0 head, and I'd LOVE to have a Genzler Bass array cab, but I'm not really in a position to spend more money on yet more bass speaker cabinets.
