Actually, I'm not recommending any avincar speakers over any of the speakers that BSW sells.
I'm recommending replacing or eliminating the OEM dash midrange. At the moment no one has a replacement. I've found one that can fit but I want to hear it with replacement woofs and tweets before I make any decisions.
I am *working* on a kit that would replace the dash mid and the other two speakers. It is not finished yet, because basically I haven't heard these drivers in the car yet.
But let's say that you eliminated the DSP amp with a respectable aftermarket 50W per corner amp, and then got any of the speakers which BSW sells - Rainbow, Dynaudio, etc. Any of those would sound great and sound MUCH better than if you connected them to the OEM amp channels and retained the OEM mid.
The avincar speakers are good speakers, very well made, but I don't say that they're better than Rainbow or DLS or Dyne or Morel.
