RE: 105db/meter NON horn loaded speakers

Posted by freddyi on April 23, 2017 at 17:33:10:
may take some input impedance cheating (and EQ)
pick 4-15's !ts ~0.3 and hot, vented box tuned to low 30's - EQ = Q=2 at ~Fb (traditional underdamped 2nd order electrical high-pass)
two "big" midrange per channel in parallel file:///C:/Users/Fenix/Downloads/MR10N301%20spec%20sheet.pdf
- not sure about a non-horn tweeter - could be compression driver on a baffle - might get 101dB from one over a limited range (?)
two paralleled Pyle pym1298 (~ same as Kappa12a) sim to 102dB in a Karlson bandpass - but do not go low
