Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

I'll be working the finishing glass and set in place with the kick panel on Monday. I'll throw some pics then. Until then I'm off to the M-4 range with the rest of the section. Gotta play with some NVGs too...

Why aim up? They're angled up about 30 degrees and out towards the source unit. Just getting a little more on axis.

I didn't like when I had my mids in an angle, Maybe been so close to my ears (a-pillar install) didn't work for me I know I had them more than 30 degrees but less than 45 degrees, isn't that against the document that Schott B. points at for "Advance System Installation? Brrrrrt after reading Lesson One, I guess 30 degrees it's ok, what do you gain or benefit with 30 degrees?, my judgment and very little experience tell me go "off-axis" completely.

"Lesson One: Off-Axis Response
When a speaker system like the Legatia is placed in an automotive environment, we hear the direct
(shortest path) and reflected (longer path) sounds, such as resonances and reverberations. The two
sounds are processed by the brain as one sound, and this influences our perception of height, width,
and depth of soundstage, as well as rearward ambience. For this reason, the off-axis radiation pattern
of any speaker in a vehicular environment has a significant influence on how natural the music
sounds.
The lesson to learn here is that most mobile audio sound systems benefit greatly from having the
front stage speakers at least partially “off-axis.” Off-axis means that the speakers are not pointing at
you, but rather at some angle less than 90 degrees away from you."

It is always a trade-off between stage (off axis sometimes helps this) and SQ.. you can make some temporary pods/baffles to try different speaker positions
