Those are bass cabs that are made out of wood (or particle board at least). And each one costs at least as much as the headrush cab.
What is your actual goal? Figure out what your actual goal is and then you can figure out which gear makes the most sense. Do you just want to use modeling because it's a trend or is it actually the best fit for what you are trying to do?
For instance, I bought my uber quads because I wanted great sounding modern cabs that would give me the headroom I wanted (something north of an average single 4x10), but lighter than just having 2 4x10s. So the uber quads are about 2/3 the size of a 4x10 with about the same frequency response, fairly close sensitivity, and similar power handling (for each one). So now I have a total 115 lb rig rated at 1200w, 45-18k, and about 100db at 1w for the pair. And I could probably really get away with just 1 of them for most gigs, and then I save about 30 pounds over my Goliath III.
I honestly don't really get the desire to to use modeling for bass. Bass is bass. There are about 3-5 basic tones more or less, and then variations on that. In a live situation, the minor variations and nuances are likely not going to be noticeable in a band mix. So for a "variety" band, you might want a vintage-y tone (which is mostly the bass and string type), modern slap tone, modern but a bit more restrained, and a nice tubey OD sound. Most of the rest of your variety will come from your effects choices. You can get every single one of those tones with the right single amp (or an amp and a preamp pedal) and about 2 or maybe 3 basses. So why spend $1500 on a helix and 300 on some cheap consumer PA speaker, when the same amount of money could get you an absolutely SMOKING rig that's actually designed for bass? And for like half that, you could have a 1000w hybrid class D SVT7 with the SVT style tone stack and built in compression, and something like a GK NEO 4x10 which would just be a straight great sounding workhorse cab and be plenty loud and weigh what, like 60 pounds? Spend like $1000 on your bass of choice with rounds, then like $500 or so on something like a mexi P or J with flats for vintage stuff. Throw in a handful of carefully selected pedals (maybe including a pre or 2) up to $1k worth, and you're in for about $4k total and what else could you really want? You definitely won't want for onstage volume, tonal options, or overall sound quality. Foregoing the fancy bass and just getting like a really nice mexi or MIJ jazz with rounds, and spending about half as much on effects, but keeping the SVT7 and NEO 4x10, you've spent about the same as JUST the Helix and the headrush cab.
As a soundguy, I always die a little inside when bands are ampless (and/or drumless). If a dude shows up with an old Trace head and a Goliath or Eden 4x10, I know that if he is halfway competent and has reasonably fresh strings, he will sound killer. If he shows up with a helix, it's like "well, now I have to do all the work of making you sound good to these people, very likely fighting against whatever poor choices you made in your patch programming".
Air is what makes sound sound good. So the more air you can get involved in your sound (and I don't just mean pushing it), the better chance you'll have of sounding awesome.
