Note: Even though the bass quality and quantity are both increased, there's less apparent bass vs the mids and highs. EQ has become far more extreme to try to rein in the mid and high but overall sounds clear:

Low: 0
Mid: -6
High: -8

I use most of the other headunit sound settings too so your mileage may vary.

 

I've the same Focal IS TOY 165 in my BRZ. It's a 6 speaker system but 2 of those (in the dash) are just tweeters.

Have found the same, plenty of bass from the Focals, but the highs and mids are very prominent. Will have a look at my EQ setting again, although I reckon they are similar to yours.

At least now I can turn up the volume and not have the door speakers break up and distort!

 

are the tweeters noticeably better?

 

The tweeters are in another league compared to the weird sounding OEM ones. Some people think the Focal are "too bright" but after EQing they sound excellent to my ears.

 

I have the 8 speaker upper trim Toyota sound system with a beatsonic amp.

The Focal are a strong upgrade of the door woofer and dash tweeter. A big difference is that the OEM door woofer had a lowpass but the Focal woofers are unrestricted. Quality of sound is very noticeably increased across the full spectrum. Easy plug n play install.

It is? Do you have a picture of it? Unless it's crossed over in the amp, in all my years doing this, that'd be the first time I ever see a factory woofer have a lowpass filter built onto it. I know a lot of aftermarket companies are doing that to split the crossover instead of having a big box to mount somewhere, typically an inline filter for the tweeter and either inline filter for the woofer or mounted onto the basket itself. Usually only see passive filters on mids and tweeters from the factory.

 

I was going based on how they sounded before I changed em out and what I thought were previous discussions about this. Looking at the OEM woofer I don't see any inline filter. Here's a far more in depth discussion where there's mention of the door woofers being fed full spectrum from the trunk amp so it does look like I'm wrong on this if the info is accurate.

Correct. That's the exact seller i bought from. Got it relatively quick from Germany via fedex. Be extra careful with the tweeters' fragile dome.
