I have no experience with that particular model so I can't tell you anything definitve about it. But I can tell you a little about VMPS. The company made its name be producing affordable true full range speakers. I mean full range 20hz to 20khz +/- 6 db and by affordable I mean something in the $1500 range per pair back in the 1990s.
I was a customer. I owned a pair of VMPS Tower II. They featured 2 12" woofers per side along with a 12" passive radiator. There were two midrange drivers and a total of 5 tweeters. They were almost 6' tall and weighed way over 100 lbs apiece and were nothing short of powerful and visceral. They were $1500 for a pair - not bad even in the 1990's.
The designer had a lot of problems with the high end audio community. The high end community doesn't care for affordable full range speakers. They feel full range speakers should be expensive and the VMPS were priced more like high end book shelf speakers. So they got bad reviews. They were blamed for being too dark sounding and too resonant.
My experience was quite different. The speakers included instructions on tuning the bass by using modeling clay around the passive radiator which was located on the bottom of the enclosure facing to the floor. The clay is included with the speakers. You just keep adding clay until the bass is tamed and in line with the other frequencies. You can do it with an SPL meter or by ear. The resultant sound was spectacular for me. I had only one pair of speakers ever that sounded better and they were way, way more expensive (and therefore approved by the high end community.)
Since then, VMPS has made some more expensive models (5 figures per pair) and has gained a little more respect from the high end audiophiles as a result.
The Tower II's I owned back in the 1990's were easily the best value overall in a full range speaker I have ever encountered in my life. Yes there are better ones and even a few cheaper ones but these were the most amazing sound for the dollar I've ever heard.
The bookshelf speakers you are considering aren't what VMPS is famous for but I'm willing to bet they are an excellent value for what they are. If I were buying bookshelf speakers sight unseen and unheard, I would have these on my list for sure. If they are going into a home theater with a powered sub, they should do a dandy job for you.
