Hi All,
Happen upon the above, looks cute & seem to use quality parts & at reasonable price.
Wondering if anyone has heard them playing.

Thanks

It says these are using the CHR-70. Any idea what the crossover frequency is?

 

[L.rivera92172]

It says 2000hz on up but you can change it from there on up and attenuation for the compression driver and mark audio driver to suit your taste

Their stated 90db efficiency leaves me scratching my head though.
I would imagine XO to be 3k & above

Hi Dave,
Wanted to thank you for recommending the Seas Fa22, it really is very nice sounding but a little forward sounding when compared to my tweaked Coral
flat 8. Been playing with phase plug & what caught me by surprise is the lenght of the phase plug affects the sound greatly.

1/ The phase plug does a couple things: fills the holeleft after you remove the dustcap.

2/ the PP will block any waves traveling across the cone. Thus pushes those rsonances up at least an octave and much of it is redirected forward.

+1. Wishful thinking, or maybe that's for 2 speakers?

Hard to grasp that even the lenght of the PP affects the sound so much.
Btw I also played with installing a ball at the tip of the PP, now this affect dispersion
as well, here size matters Lol. Pinpong ball too big cuts too much of highs away.

Thanks again Dave
