Many people refuse to acknowledge that you can work professionally with their products. However, I've seen those speakers in many studios where professional work gets done.
Behringer was somehow the "China of the music & audio world" : cheap clones of more expensive pro gears. While usually visually decent, it could be hit or miss soundwise. Mic preamps, guitar pedals or cabinets were bad for example while monitors (like the one you linked) were OK for the price.
Recently they bought companies like Midas and TC Electronics and I think their products have been getting better. Not enough for me to consider them usually but still :)
About speakers the real problem will only be the room and the benefits of expensive speakers are usually wasted because of that. There is only so much you can do treat a living room without cluttering it. The WAF of bass traps is not high.
So while we do get cheaper products that are 'good enough' from Behringer, for a long time they had a deleterious effect on the industry - I know of a number of products that didn't make it to market because it was known that Behringer would clone the design ..
I have experience with their cheap end mixer, and it was good until it started to slowly break down. One component at the time. Luckily it had some excess potential, so in terms of play hours/price it was still OK.
One problem though is that the existence of a company like Behringer making cheap products that are often good enough, is that it can tend to destroy the mid-market stuff that used to exist. Once that happens, your choice is either to buy something dirt cheap, or some ridiculously expensive "boutique" item, because there's nothing left in between any more.
(I'm not suggesting this is Behringer's fault, it just seems to be how things go when a mass market comes along.)
JBL LSR range is also a low cost budget monitor champ.
These are also studio monitors by the way, so they are not always great for hifi listening - I use separate speakers for that.
