Default AE New Drivers

Hey guys John has the New TD6M & TD8M up on the website with charts and graphs. Take a look they look great. Would one of these be a better option that the ATC 75/150S. I was just looking at the TD8M with the Apollo Upgrade since it would allow me cross over lower say 200-250hz to include all midrange frequencies. Chime in, this is what we've been waiting on the New AE TD 6" & 8" midranges for a 3-way build. Excited to say the least.

The RAAL 70x20XR CSD shows the benefit of a 3k crossover over the 1.5kHz - 2kHz crossovers favored with the TD8M - TD6M polars and cone breakup SPL artifacts as illustrated in my earlier TD6M CAD design in Post #102 and #117. The latest TD6M SPL data continues to show similar polars and cone breakup.

Work with Jim Salk to get a low diffraction 3-way cabinet. Do you have a better design with the SM75-150S dome than the Avalon-style cabinet I modeled in Post #117? Do you favor wide and curvy?

Default Cabinet design

Thanks for your input, we switch cabinet design to clone the Wilson Audio Alexia but with one TD12S woofer with better bracing the added convenience of being able to switch out the midrange enclosure. He's building one for ATC 75/150S & Raal am70-20xr and one for the Audio Technology C-Quenze 15 H 52 06 13 SD & Transducer Labs N26CR2-G: 26mm Pure Al203 Ceramic Dome Tweeter. We decided this would give me the best of both worlds. What do you think.

Default Comparing the drives

This way I can compare the different combinations to see which sound I like the best in my listening room and sell the other drivers that I don't like or maybe keep both combos for a change of flavor. With the Pass Labs 3 way XVR-1 I can customize the crossover points and slopes to my taste.
