db_speakerbox Posted August 27, 2015 Report Share Posted August 27, 2015 Nice! Watched vid and thought no way that is 20hz. Its way lower than that and then realized it was in slow mo lol. Listening impressions with new port? Link to comment Share on other sites More sharing options...
Mrop Posted August 27, 2015 Author Report Share Posted August 27, 2015 Everything started to flex like hell, but the "presence" of the bass is gone. It feels and sounds like a proper 4th order now, but the bass was more soft and deep without the port.Hard to describe, but first thought after the port was up was that i want it gone.. It was more musical without the port, but i'm starting to digg the lowlows more tho. But you cannot have anything when you're chasing your 160! The box still plays from 25 up to 50'ish. And the pressure in the ported section has helped in better excursion handling. I am not afraid anymore to go full tilt 20Hz, when without the port it was a "NONO" under 25Hz... I enjoy mostly at 28-36Hz -range, as it makes my windshield flex like hell!BTW!! I made some exterior changes: Made custom headlamps with spare parts from my another 245 volvo www.peranurkka.net Link to comment Share on other sites More sharing options...

db_speakerbox Posted September 1, 2015 Report Share Posted September 1, 2015 Congrats! I think if you could keep your voltage up a little higher you will be there! .25 is brutal tho, drawing some serious current. Love m4a amps, they are beast! What is your current port?
