Internal software solutions like Audyssey and Dirac Live have been the go to for those looking to tweak the sound of their systems to accommodate ones room for the ultimate sound quality and balance. I understand that this comes in very handy for multi-channel amplification and speakers for HT but let's suppose one has a AV processor versus a receiver and or just wants to EQ for Stereo only? Why not use multi channel external EQ and not use internal digital processing like Dirac or other processing? There are fantastic low cost EQ one being the Behringer Ultragraph Pro FBQ1502HD 15-band Stereo Graphic Equalizer with FBQ Feedback Detection? \n\nTaking it a step further one sees outlandish priced speaker systems with crossovers, so why not use external EQ and bypass the crossovers? I see this as a great solution for DIY systems especially with separation of drivers being not all in the same box. I would think one can create an amazing low cost speaker system using external EQ vs software based EQ and crossovers. Thoughts?
