i don´t know is it this phase lump what comes up when crossing tpl too low and makes it sound bit offensive.
i now play my system 18sound nsd1095+1086 crossing 2,5k, thats too much for jbl mid horn and 1" cd is more dirtier sounding than tpl200h is.
phase curve is much more flat 1095+1085 than with tpl200h
funktion one resolution 2 8" midrange horn
raw driver with and without waveguide
810hz dip is from back enclosure, went away with wool sock but 2300hz is driver related
been listening for awhile and it really goes high, 6k crossing looks easy,
feels beaming lets see polars some day
now i have compact inlow 135hz horns
funktion ones are now bitum damped
took polars 0-180 outdoors too
i dont know if that 135hz horn is a keeper, phase response looks like it have to be crossed over 200hz (LPBW), 200-400hz with inlow
im not happy about going to 200hz with bms 18"
inlow 135 hz horn being open on back dipole horn i had idea closing its back.
here you go, 15ms window around 80cm from mouth in-room
yesterday i did DIY boxes for funktion ones... with jigsaw and glue
build quality is finest of fine
such small boxes as these theres lots of resonances so thousand and one measurements showed more filling the better.
maybe i have to buy lamb wool or other to see whats difference between fillings on midrange.
less felt 200hz goes up 1-2db, 1100hz dip goes 2-3db deeper.
this automotive felt musn´t be the best?
first run with these.
inlow is +10db over 12" bms in sealed
old set was really well tuned, feels really awkward after those
funktion 1 mid horn is too shallow to go 250hz with flat phase response, jbl is quite flat 420-2200hz.
theres an bit of an reflection from lower horn, i put pillow and cat pouch on it for a starter
bass what i got now, my lord, 70´s 9" heco vs. modern 18" high end bms, that is so dirty sounding
carpenter friend just started his 4weeks vacation so no tapped horn for long time

Hey.
Which are the JBL that are quite flat from 420 to 2200Hz?
