I'm not aware of any tests but at the end of the day these are small tower speakers with an 8" "subwoofer" and what would are presumably 2 x 4" midwoofers and a 25mm dome tweeter in an MTM configuration. If they're done well, they will be nice mid-fi speakers with average levels of nonlinear distortion, quite wide horizontal dispersion, and a somewhat narrow vertical sweet spot due to the MTM configuration. Could range from terrible to very good, but would be very unlikely to be competitive with the best active speakers in their price range, to which one could easily add a bluetooth receiver if one wished. They do weigh 19Kg though, so if the cabinets are well-engineered they should be pretty inert and non-resonant. They also seem to be a nice shape for minimising baffle edge diffraction, although it's hard to know for sure since the true baffle is hidden behind the grill cover and may or may not contain edges/discontinuities that are not visible without pulling the thing apart.
Personally at that price I'd go for something measured and verified to perform excellently.
