Jim - please keep us apprised of how the 2.3s do for you. The original 2.3 coax was the pioneer coax. Do you know when its upgrade happened?

My original prototype Brazilian Rosewood O2s from 1976 we given to our parents as an early appreciation gift for their support. They are in storage at my youngest brother's house in Virginia; I'll get them this summer and, of course, soup them up a little. The O2 actually started the audiophile ball rolling. The O1 was a 10" 2-way Rock-n-Roll Boogie Machine with 3rd order slopes and huge magnets for high efficiency and the EQ for 30 Hz bass . . .  but not much finesse. Some early supporters asked if Jim could design something more refined, which became the O2 6.5" ported 2-way with second order slopes. Quite lovely for its day. I will apply the boundary-layer airflow technology under present development to the port and driver circumferences, add some absorption to the baffle to reduce diffraction and upgrade the passive components. And I bet we'll have a sweet little bookshelf monitor.

Thank you,
Tom

@jafant Looks like either a qx-5 or dx-5 into an ax-5 will clip at about “40” on the indicator, assuming full output CD such as most rock recordings. Only a small difference between the models. This is for XLR connections. RCA will be more like “44”. This also assumes a stock AX-5. Apparently, there is a version with 6 dB gain resistors, so that will modify accordingly. Keep in mind this is not an exact science and other factors can influence the onset of clipping. 

@tomthiel I can’t wait to hear your airflow technology. I’m wondering how that might modify image density.

You guys facing inclement weather -stay safe and warm out there.

Beetle - patents are in the works, so no substantive news yet. I am beta-developing the technology using the CS1.6 as my test mule. The 1.6 / 1.7 slotted port is unusual in its airflow dynamics. Ports care where they are placed in their enclosures. The 1.6 long slot side-steps some of those placement issues by being placed in the lower chamber at large. So its airflow dynamics are more complex than usual, since the broad placement creates a gradient of interface parameters with the enclosure resonances.

I can report first-hand that the slot works.
I can also report that the interface technology will improve it as well as improve speakers in general - a fluid dynamics solution for fluid dynamics problems.

Plenty more to tell when I can.
