OK, I'm calling it a Modula PSD at this point, but the initials have changed and evolved depending on the brands of parts- the "P" has been constant, because of the PTT6.5X04-NFA woofer.
What's with the other letters at this point?
"S" = Seas, for Seas H1499 DXT tweeter. I picked up samples and did baseline measurements in 2019, saw some positive stuff but also figured optimizing a crossover would take some effort- day job was too demanding then.
"D" = Dayton RSS210PR, the smaller PR I've been waiting and hoping for, for certain system applications.
The LF analysis with two PRs looks very promising...
This PuriFi driver has some "quirks" regarding response, as does the DXT. But it seems possible to get them dance together nicely...
With data just from a sealed cabinet, without the extended LF performance, the crossover design has been optimized "on paper" from driver measurements.
Care has been taken to insure that the load impedance is not demanding high current monoblocks that this author is far too fond of...
Components are mostly on hand for a test build, some crossover parts pending. It's in the queue... And Steve has local friends that want a build like this!
