Mr. Thiel
Thank You for the great detail and for giving up so much of your time .
"A factor that contributes to "great bass" is that of articulation which, in a first-order design, includes the low end of the mid-range driver. Jim's 3.7 XO treatment is much more sophisticated and uses better parts than the 2.7 due to budget constraints and designer choices. The 2.7 midrange is fed through a 400uF electrolytic cap, albeit with a PP and styrene bypass in parallel. The 3.7 uses a bank of 75uF polypropylene caps with a styrene bypass. Multiple smaller PP caps provide faster reactions and less distortion than a large electrolytic. "
This explains a lot .
Hopefully when you and Rob develop an upgrade for the 2.7s
they will based on the 3.7s design with new and higher grade components .
