    Hi Quality with Unlimited Possibilities

    Posted by Nick Daerr on Oct 31, 2026

    Using just a radio and a cock box was 2010..Have you ever put together your system and felt it could be a bit better then what you paid for? Well this is your answer.. If you want to tune every single speaker and or channel on your ride this is the key. As well Being this has a 32-bit chip DAC and after owning a EZDSP612+ this one blows that one away being technology advanced, hands down this is an incredible piece of gear and keeps up with 1000$+ DSPs. Seriously don't pass up this gem to maximize the capabilities of your amplifiers and extend the life of all your equipment. 5stars! Thanks! D4S!

    1216 DSP

    Posted by Nick Hale on May 07, 2026

    What a value! Most 16 channel DSPs with these features will run you $1,600 minimum. IMO sounds better than the D4S 68+DSP. It definitely has a better sounding DAC than the other D4S DSPs. It’s not advertised as a High-res DSP but its frequency response output go up to 40,000Hz and sounds very good. It does not go on sale very often but when it does, it’s $100 off. It’s still a good deal at $600 though. My only criticism would be that it does not work with the current Down 4 Sound controller. That may be a criticism of the controller itself not the DSP.
