Hi everyone,
I am chasing a measured impedance graph or plot for a stock pair of Polk SDA SRS 1.2TL speakers.
I know that Polk's official literature never released a factory curve and only stated that they are "compatible with 8 ohm outputs". Because of that proprietary gap, I am trying to see if anyone in the community has personally pulled an actual measured curve across the 20Hz–20kHz spectrum using a Dayton DATS, WT3, or similar analyzer.
We are specifically looking to analyse the reactive current phase angles and the worst-case impedance dips. The goal is to calculate a parallel current-equalisation network to flatten out the load and mitigate the back-EMF reaction feedback acting on the driving amplifier.
Does anyone have a saved measurement plot or a link to an old thread where a member mapped out a stock unit?
Cheers!
