All of the above.
I've been using wide bandwidth, high fidelity type cabs for decades simply because I don't want a baked in tone from an amp/cab but the flexibility to create it, and vary it according to my needs. Next year I might be getting back together with the girls to gig again and I might be using bass, electric and acoustic guitar and baritone, depending on what we actually play musically. Add a clean amp, a 'FRFR' cab and a modeller like a Stomp and I can get all the bandwidth and clean SPL I need for any type of music in the one rig.
I design and build my own rigs, but the best I've heard in a single box is the Yamaha DXR15.2.
