Stereo Integrity TM65 MkII drivers...

ChopsZ · 08-20-2017, 02:51 PM

Just for the hell of it, I ran the RTA on my system as it sits, nothing more than the Pioneer head unit, Memphis 2.75" dash speakers and bone stock base 6.5" door speakers.

I used my Dell laptop running Room EQ Wizard (REW) into the head unit via the new AUX input I installed in the dash cubby with an AudioQuest 1/8" cable, and the miniDSP UMIK-1 mic.

This isn't a perfect session as it's about 210*F outside as well as nosy neighbors wondering around (stinkin' apartment complex). So I had the engine running, AC running and me sitting in the passenger seat. I tried keeping my legs and laptop out of the way of the passenger door speaker as much as possible. This means I was sitting Indian style in the seat (which was a bit uncomfortable) and the laptop folded in half on my stomach.

To overcome ambient noise of the engine and AC running, I ran the pink noise up around 90 dB. With the pink noise playing, I really couldn't hear the engine and definitely not the AC as I had it running on its lowest setting. Though from the looks of the measurements, the mic was still picking up engine/exhaust noise, so just ignore the measurements from about 50 Hz down.

It's quite obvious in the graphs that I'm getting a fairly decent suck-out between 3 kHz and 6 kHz.

Other than that, it sounds amazingly good! Doing nothing else other than tweaking the EQ for a little flatter response, it made a huge improvement! I'm very impressed in the sound stage, imaging and width as well as the overall sound, all of which improved with the tweaking.

I know this sounds crazy, but I hope the Stereo Integrity setup sounds as good, only because I love all of the mids and vocals up on the dash.

Anyway, a few pics...

The red line shows the initial curve before tweaking...

And what the EQ looks like...

Are these the drivers in the dash to replace the ultra ear piercing harsh stock tweets? ( Whoever invented the stock tweets should be punched ):

PRX275 - Memphis Car Audio

Thinking of doing as much sound deadening as possible before going the amp/hu route...

Too late! ordered 'em! Gonna see how they work out with the stock head unit... Then focus on the MF'n road noise by doing the wheel wells before dropping $$$ on an amp+hu... as I listen to more podcasts than music these days.
