The goal was to inexpensively improve the sound on the Rio4, without replacing the MHC. Chose between JBL, HERTZ and these in the same price range. Along the way, did Shumko in the doorway in three layers. The speakers were planted through rubber mastic on 22mm plywood rings (under the same landing depth with standard speakers). In general, controversial impressions. There are no complaints about the main speakers, but there is not enough bass depth, the tweeters play loudly, but they obviously do not play the sound correctly, capturing the frequency range that they generally "can't do". The Focal RSX-165 in the rear doors is generally cut in the frequencies of the MHC both at the top and at the bottom - it makes no sense to put two-component speakers back . At the same time, I don’t think that JBL or HERTZ would play much better. As a conclusion - cheap and high quality does not work .
