Experimenting with imaging in a 3-way design

Hey all,

I will be honest. I have been working with audio for many years, engineering source parameters as an ME, and I am taking a deep dive into building my ideal mastering main speakers.

No need to go into tons of detail in terms of driver specs etc too much. The plan is to use a 10" sub, 6" mid, and planar tweeter.

Many of my favorite designs use an MTM -type format, at least with the tweeter below the mid. Grimm LS1 and Stratus Gold come to mind.

Another thing I've noticed in the best presentations I've heard is having mirrored tweeters on the outside of the speaker. This seems to improve imaging as well, although in a different way than MTM.

I have a terribly inaccurate two-second mockup that shows two concepts for the design. Would love to hear people's opinions about what would perform better.

If anyone is interested in more aspects of the design, I'd be happy to share them. I just figure that I'm verbose enough as it is. haha

It's not really a MTM unless both "M"s are crossed to the "T" at the same frequency. Thus MTW is something different and by definition loses the ability to "pull the lobe" back up into the on-axis plane.

Generally, isnt it best to have the least distance possible between drivers that cross to the next; that implies back to the usual TMW stack?

I always dreamed (I'm a dreamer) of a multi way build with an individual cabinet for each driver. Then I could stack them in any arrangement I want for imaging experiments. I wonder what the crossover would look like for the "M" with a -6db switch on the back, for when you want to use two?
