Hi Norman,
yes this driver sings still very well. I'm planning to implement a tweeter, it works nicely without, but the sweet spot is thight unless I toe the speakers in to a "isocele" configuration. When I do that the deepth of the stage comes to life, but the width is a bit shrinked. I would a sound that cames out the speakers, like left of the left speaker and right of the right speaker. I had this kind of stage with a W4 1320 in a MLTL.
The speaker starts to beam at 2Khz-ish, I wonder if the crossover frequency is better at 2K, or 5Khz to let all the "idiophile magic" of the voice, but there will be some lobbing problems between the dispersion of the FR and the dispersion of the tweeter.
Anyone did experiment FR + tweeter?
regards,
seb

Me.
Nothing wrong with a 6db time aligned crossover, at all.
24db @ 5khz is close but not better to my ears.
Given the impedance plot is flat on th 2145, that will make it much easier to do a crossover.

I design a MLTL for the W8 2145
30Hz@-3dB
length: 143cm
CSA 880cm²
driver 62cm from the top
port: 110cm² area, length: 12cm
stuff the up 2/3 with 1Kg of fiber.
