The VR4HSE is a magnificant design.
The gain system(rear tweet, read the manual) is very effective for 3d'ing the system.
The speaker can disappear really well. For sure use an amp with good bottom end control. As with all speaker that go deeply, a mushy sounding amp can be a disaster.
Plus you need rear room, behind the speakers to allow for both the rear tweet, as well as the omnipolar bass.
Mine are excellent, with dynamics of a horn, clarity exceeding an electrostatic, and imaging which seems lifelike.
You can not go wrong. Music is not about listening, it is about being inside and enjoying. These allow you to do this. Mind are only three to four months old and still breaking in, but now blooming very well. I say they outperform most speakers up to about 20K, and some above that. The bass is up about a db too loud for my taste, but you can adjust this by bringing more stuffing into the front port, from inside the cabinet according to the manual. How to do this with the cloth in place is not explained, but you can do it. Of course you may like the extra bass. I do most of the time. But on really bass heavy, and synth'd stuff it can become a little much.
I look forward to getting them into a larger room. My new listening room is two stories by 20x18. That will tell me even more.
