Difference btwn DSP speaker and Non-DSP speaker?
 

Hello,

I'm upgrading my DSP speakers & Sub woofers,
after all, I'd like to sell my DSP speakers (2 tweeter, 4 mid bass, 2 front midrange and 2 rear mid range) but have no idea what's the value of them.
so basically, what's the difference between non-dsp speakers and dsp speakers and how much are they going for?
I've used them for 28,900 miles with Ice>Link Plus.
anyone can help me?

Thank you.
