HU is a Pioneer DEH-80PRS running 3 way active with time alignment and 16 band EQ
Rockford Fosgate Punch 100ix running tweeters
Rockford Fosgate Punch 4040 DSM bridged mids
Rockford Fosgate Punch 40i DSM bridged running sub
Speakers
Audison Voce tweeters in custom pillars
Audison Voce 6.5” mids on aluminium baffles bolted to the solid and sealed inner door skins
Rockford Fosgate Audiophile RFA810 10 inch sub running IB on a 72mm baffle under the rear deck
I’m measuring with a RadioShack SPL meter at the drivers headrest with a phono to headphone adaptor into my laptop and I’m running a calibration file on the meter.
I’ve downloaded the full range Periodic Pink noise as a WAV File and I’m playing it via my phone into the HU via USB input
The response curve looks ok after a bit of EQing but the bass roll off is crazy and it can’t be true as if anything the bass is on the heavy side.
Is there something obvious that I’m missing?
