Yaris with new audio DPS module installed - Gadget or really increasing sound quality

[Flyingmatdes]

Hi Folks, I'm new on this forum and I like it already... nice to have a Yaris forum.

I'm unfortunately not an Yaris owner, but I'm planning to buy one in following months.

I saw that (in Canada) we havee an optional sound enhancer module sold for almost 350$ called DPS from Bongiovi acoustic. It's supposed to enhanced (and correct) the sound pattern in your car. The nice thing is this module is supposed to work with your Yaris factory speaker....no need to change them...

I'm wondering if this module worth it's price or I rather choose better speaker without spending 350$ on a DPS module...

Somebody tried the difference in a Yaris ?
