Man, I was really disappointed in reading your review of the Morel Tempo Ultra 602s. Your experience and mine are totally different. I'm very pleased with the bass response. I think it is fairly deep and pretty tight. And, the tweeters are outstanding. I can play these speakers loud for a long time and NOT get ear fatigue. I love that about these speakers.
But, until I read your reviews, I was absolutely sure I would be getting another set when I get another car. Now, I am not so sure. I did appreciate your insights and your efforts with starting (and following through on) this thread.
Now, I did not have the opportunity to compare my Tempo Ultras with the other brands as you had. I did compare them to an appropriately prices set of Focals (I don't remember the model # of them) at a local shop and did like the Morels better. I guess I would have to look at those HSKs in the future, but I hear they have been discontinued by Hertz.
All in all, I am still absolutely pleased with my Tempo Ultra 602s. By far, these are the best front stage speakers I have ever owned.
