Show me a DSP IC that lacks power to make a pole-zero mover (bass equalisation), and the three simple single element equalisations that
@amirm applied. Any DSP IC on the market has more than enough power for the job.
I did say using the DSP only on the bass signal path is stupid. Not due to my special powers but my trust in engineering notion the designers will have.
Thanks for your reply. I was more wondering haw you know it only needed 3 elements of equalisation? My question was more how do you know that
no equalisation was applied, not the elements that where left out, but that there was zero equalisation done. Again, it clearly states that they do phase correction, that it's FIR but you said DSP was used for bass extension only, my point is that those are two contradictory statement Phase correction is "using DSP", that's at least one thing they used DSP for that is not bass management, ADAU1701 looks like quite a rudimentory DSP FIR chip. It looks limited in it's number of taps somehow but I agree you know better, you confirm that they could have done all this? FIR for phase and IIR for EQ? FIR for both? How many taps and bands are necessary? Me the point I am trying to bring is i am 100% sure you are competent at designing speakers, but you did not design these. So many time we look at a measurment report and we hear comments in the line of, why didn't they do that, it's free. And then again, we get unperfect speakers all the time, but it have been so easy to make it perfect, and the next one is not any better. I admit that I really have difficulty buying that. Engineer don't function like that. I never could pictture an engineer going, hey all that's missing is spending 5 minutes dialing in 3 bands of EQ, but hey I'm lazy, I'm just gonna release it like that... It's a 150$ speaker and I am 100% certain that the flaws it has as been studied, that they've put the engineering where it mattered for them, according to budget, design goal, marketing, many different reason that we'll never knoow, but the flaws in the response of this speaker, there is a decision, a reason behind that and it's not because the designer didn't know how to use an EQ.
