Main Frequency Response

notes included in photo



**as of 7/16/2016**

Bass Tone Control

I can't to go by with just ONE bass response. Some movies just need that bit more bass and sometimes there is one that needs to be tamed a bit. Or maybe I just feel like having more or less depending on my mood. With much trial and error I found that simply adjusting the BASS TONE CONTROL on the Yamaha to bet the most convenient and useful way to manage my need for changing the response on-the-fly. This next graph shows the effects of this tone control (only CC shown) and it's total range.

Notes included in photo.



**frequency response shown as of 7/16/2016**


Tactile Response

This information is related to the TACTILE RESPONSE of this system. These measurements were taken from a Nexus 7 tablet using the VIBSENSOR app available on the Android market (iOS also available). Essentially this information is showing the response shape and power of the TACTILE RESPONSE which is different from the above FREQUENCY RESPONSE graphs. Frequency response, as you know, is the audible range measured. These tactile response graphs show how you FEEL the bass. Frequency response shows you what you HEAR.

For more information about Vibsensor and the topic of TACTILE RESPONSE see this thread: The VibSensor Accelerometer Test Thread

As somebody who is a big fan of the "wall of sound" look and sound, job well done. I bet it sounds awesome. Though I think I see a couple of square inches of free space where you could have probably added another speaker...whats up with that slacker???

Love the mad scientist approach Scott. I like to think of you in your room with a white lab coat and goggles conjuring up your next permutation. Just one evolving experiment. Thanks for sharing all your experience with us.

What are the white things on the horns that look like little pieces of paper?

They used to be big pieces of paper.

Grant, I took that picture while I was still assembling everything and had labels "L, C and R" on each to keep consistency. They aren't on there anymore.

No but I guess I can post some of those too eventually. Every so often I go and make changes so that renders most of my "up to date" graphs as not so up-to-date. By the time I've posted one, it's already changed....maybe.

I think I did one last week when I took these pics (see the mic?) so I'll upload one or something.

Don't bother. They'll just get blown out by the subs.
Heck, they could probably get blown out by the horns.

Be honest, did that space use to be your walk-in closet?
