Aside from what that particular instrument is or is not, I've got to ask whether you've ever played a Spector? While they have that very cool design that I think of as "that Spector layout", it's a design that includes a relatively short upper horn and the bridge is mounted on the body at a location that's up and away from the "bottom" edge. Playing one of these strapped on the shoulder while standing up can bring ergonomic challenges for some and the layout might also come with significant neck dive. Of course much of this depends on you, how you like to have a bass sit on you, and the particular bass in question.
I'm not at all throwing this brand under the bus - I had a Korean SSD (Stuart Spector Design) NS-94 some years ago that treated me well for many years early on. But even that variant of the Spector blueprint had no better than a mediocre fit and balance. It worked okay for me because I was younger and it was easier for me to accommodate a so-so fit with any bass. It also sounded pretty dang good.
In case you're not familiar with these instruments, I absolutely recommend spending a little chunk of time getting to know one or two of them to see how they fit you on a strap. Aside from the balance (that won't be much of a mystery after only a couple of minutes on a strap), I can say for sure that the listed weight would be an absolute no go for me. I put up with a decent parts J-bass for a lot of years that weighs 10.5 lbs. Terrific instrument that worked for me for a long time, but now that I'm 58, I just refuse to tolerate that load on my shoulder all night, even with a strap that's almost as wide as a doormat.
I'd only consider getting an 11.4 lb. bass for myself if it was perhaps a 6-string that I'd only use for a song or two at my gigs or that I'd mostly play while sitting down. No injuries or health issues here, but I'm at the point where I won't give any 4-string a second look if it's beyond 9.0 lbs. Your situation might be different in terms of what you can handle, but if that scale is accurate, that bass is really heavy.
