06 AC w/oem HU Speaker Upgrade brands?

theyre on the way...
JBL Club 64CSQ 1 $194.89
JBL Club 64SQ 1 $129.15

im sure whats left of my oem radio will sound better for a few months til I can find time to replace it w/updated HU; for now
I cant see these speaks being any worsethan the oem's. Have to admit tho, for 19yr olds, they sound good, in a 2006-stock way. IE: non jbl, thru oem amp [fujitsu?], BUT not much depth of sound or distinction.

 

Getting ready for install and reviewing the Crutchfield & JBL instructions.
Question:
Can anybody who has the Component Club 64CSQs [or any JBL Club series speaks] tell me specifically what I get [will I even hear the difference] from the X-over switch setting of 0db vs. -3db, before I bury it in the door panel?

 

Oh this is a fun one.

While that +3 actually has a plus in front of it, that setting of 0 should actually be nerfing the tweeter (specifically) by -3db, and maybe that's what you meant. Unless JBL is doing something markedly different than I've historically experienced, that setting is purely toggling the relationship of power between the tweeter and mid, i.e. at the 0, the tweeter will be nerfed by -3db, and at +3db, the tweeter will be playing at the "same" level as the speaker.

My take/general default/suggestion? Before bolting up the door panels etc. fire up the radio, and listen set to it set at 0db and +3db. What should you be listening for? Listen to how loud the mid is, in relation to the tweeter. Set it to 0, then switch to +3. Do you notice the tweeter more than the mid or vice-versa, in either position, such that it sounds lopsided, like maybe the highs are too sharp/crisp? If so, avoid that setting. I usually prefer the mid to be louder than my tweeter, personally.

If you notice the tweeter is unusually shrill with the +3 setting, it'll be more noticeable later, set it to 0db. It honestly varies from speaker manufacturer to speaker manufacturer, specifically based on the tweeter design. Some are brighter/sharper than others. I also find the source of power (internal HU amp vs. external amp) makes a difference.

Hopefully this helps? It's a really weird thing to explain, I never really think about it because I always listen to things before buttoning it all up and will check that. I'm typically using external amps, and I'll use my amps/crossover/DSP to tweak things out. I don't believe my Club components had a setting on the crossover.

 

ok, my gut was telling me to try both settings for a listen test, before buttoning up, but not yet installed. Not a word stated, but I'd expect JBL to describe the 2 settings in their instruction pdf; then again, maybe its audiophile generic meta data thing.
Yes, @Shifty, correct; it is 0 or +3, which likely means it minimizes tweeter hi frequency compared to the 6" driver tweeter?
Adding to the cryptic settings, the expressed numeric value, dB, increases as volume [or output power] decreases... [at least thats according to VOL +/- buttons on my 40 yr old SONY home Amp/Receiver]. Not being an audio engineering educated person, thats just my best guess.

Anyway, can hardly wait to fire this system up. Just set the tweets in the door panels, but waiting for re-paint to finish and get truck in dr/way to install Mid/Woofs and replace door panels.
