I personally thought that the hk mids sounded a little thin, and the tweeters a little more forward, than I like. Now, they sounded pretty good - and for the budget we were working with, I think that leaving them stock and enhancing the sub-bass was a good choice.

But I don't have any doubt that Morel Hybrid Ovation, for instance, have better heft in the midbass and are a little warmer.

The Rainbow 210.25? I think the tweeters are just a little smoother while still having a similar level of detail (I think the Rainbow CAL25 is an amazing tweeter for the money), and the mid is similar. I suspect that some of the harshness or forwardness I hear is the top end of the 4" mid, and there's no low-pass crossover present to help tame that top end. The Rainbow does have a very good passive crossover (better than the new Morel HO 4 II).

But it's worth mentioning that IMO upgrading the speakers requires adding amp channels. The customer is willing to do this in future. However, adding two amp channels AND front speakers and a matching center does kick the price up. I think this is the right approach.

I still wanna hear the Dynaudio 1400 Esotar 4"
I dropped my son off for basketball practice tonight so I had an hour to kill and I decided to try and duplicate your set-up with the higher x-over points to see what impact it would have on the sound of the system. Honestly, I did not hear much of a difference from a tonality standpoint, but there definitely was a "draw" towards the center speaker. The image was shifted about 6" away from my "perfect spot" (right in front of me), over towards the middle of the dash, and I swear I could locate certain sounds as coming directly from the speaker, whereas before, with my old x-over points, none of the speakers were "detectable" at all. So my little experiment confirms that x-over points for front components and center channels need to be set as low as the speakers allow, otherwise you may have funky results.
