For those interested, here are the "naked" close-mic'ed curves of the rears, and dash tweets with Forscan in "flat eq" and with head unit tone controls zeroed. REAR Speaker. GREEN = zeroed head unit tone controls. BLUE = tone controls optimized, as shown in previous image. Notice the...

I was ignoring the 300 Hz high pass scenario. Only referencing before and after setting of Forscan "flat EQ I don't have the before snaps at the office to post. Will try and remember to post later or on the weekend. I also used a different app for the "before", as it was right after I...

Well, I can't speak for what people "notice", and many are notoriously poor at A/B comparisons if the switch is 30 sec to several minutes apart. I know what the MEASURED acoustical response differences are between factory and "flat eq" settings in Forscan.

The curve above is measuring the effective power response, which should NOT be flat but have a smoothly falling response of .5 to 1 dB/oct. I drew the red line to illustrate how well the measured curve fits a smoothly falling line. This represents how you will perceive the overall timbre of the...

Likely because your sub crossover is set too high (above 55Hz or so), exciting a cab resonance around 65 Hz, and because the Forscan "flat eq" setting leaves the the factory speaker acoustical response with a very broad suckout from about 150 to 700Hz. The effect is that the low bass from the...

Yes, "flat EQ" removes ALL electrical LF rolloff, and the 70Hz LF boost, HF boost and other small EQ, to ALL 4 speaker circuits for XL/XLT audio units.

It does. The electrical response is not longer steeply rolled off at 60Hz to ALL speakers circuits when "flat EQ" is employed.

Doesn't matter which XL or XLT speaker circuit(s) you tap for the sub, when you set Forscan to "flat EQ". The rear speakers are a far EASIER place to tap.

With Forscan set to "flat EQ" the "All seats" and "Driver seat" are identical--no difference in response or speaker levels.

Maybe the poll should also ask EB or Hybrid?

24p-p, 8.5vrms from the head unit. 8 ohm speakers, up front at least, that I've found. 9W max. Net system sensitivity is likely ~92dB, so max spl ~102dB peaks midrange (voice range). Because of the factory EQ LF boost, in practice the max system output seems to be high 80's dB. I will note...

Resetting the BMS erases learned charge history/strategy, and makes it thoroughly sniff the battery behavior again. When used on a battery that's been in service for a while, it can help a bit. Similar to discharging a cell phone to zero and recharging to 100% on many phones recalibrates the...

Then, I guess you'll come to a stop. :wink:

Loudspeakers/system response, before, after...

Mine was free. Done at work parking lot.

Any measurements?

I would buy again. Despite dash rattles, the occasional rumble-strip pulsations from the drivetrain, and poor AM/FM reception, it is fundamentally the right size, right utility, right passenger space, right drivability and amenities, and the right price for the market we are in. I also got...

Yep, many Xinese plastics--especially softer ones-- have poor quality unstable plasticizers that leach out rapidly with heat and react with surfaces they contact. Heat can break them down and make them chemically agressive, I'm told. My bet is the dash cover caused it.

Astroglide silcone is also quite effective. I won't post the blush-worthy Amazon link.
