Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

I was about to say...that extra space in there is going bye-bye with a second woofer up front.

Would you be ditching the foam and the inserts under the carpet for a little more space?

I'm working on a center console idea after INAC next month.

In competition, there is a category of judging for linearity at the sub bass level. This is where we get detailed and picky. You could have GREAT sound at a low to moderate level but let's say your amplifier and sub don't mesh well because of power issues at high linearity...well, you get kicked down a couple points for it.

There's also the category of imaging, ambiance, and tonality. All are affected by the sub woofer at some level. It all blends really. If your bass is too overpowering, much like the dual DD1508 setup I messed with earlier this year, you get knocked down for it. That instance had a peaky enclosure with STOOOPID amounts of bass. I took the level down 12 dB at the source to try and tame the amplitude of the signal. I replaced that setup with the ID8 then dual ID8s. I don't know why I even considered a vented DD option (aside from flipping the bird to the SQ world for the hell of it).

There is one reason I'm not using a Hybrid Imagine woofer yet...actually two. One, I get better response from the sealed enclosure woofers and there's a Legatia 13 coming out in a few months that I get to play with.

No, I'm not going to remove anything under the carpet, MLV layer is above and rather keep the road noise away, and since it's only an experiment why bother now. If I really need the extra space I will, for sure.

Center console idea? interesting? but I can imagine it's going to be hard to accomplish. Expand please.

Thanks for the info about linearity at the sub bass level, I love to be picky in that department.

I know about the Legatia 13 coming soon, for now I get to play with 2-i6SWs I went to the post office today and there she was!

Just to expand more on this...

If every thing works in a positive way... I'm not only going to take out the inserts and foam... I'm thinking about cutting the metal floor and lowering it about 2 inches, then I can build a dual box for 2 i6SW's and rise the floor 1.5 inches.

Letting the vents breath the same way facing forward towards the center of the fire wall.

Just another crazy idea so I don't call this Build "Done!"
