I upgraded to a 90D without the premium sound this summer and I am looking for recommendations on speakers as the sound is just not the same. I was hoping to shop for an upgrade that was ~2k installed. Is Light Harmonic still around? There website/blog don't appear to have been updated for over a year... I stopped by two installers today and both were recommending speakers from Focal, with really expensive amps and dsps... and adding a subwoofer, price was 3500-4500. One was recommending the Focal PS 165F and the other the FX Are there any good drop in replacements for the door speakers and tweeters? Something will low enough bass that I wouldn't need worry about a sub?
