bass 80hz lowpass

Click the image to open in full size.
low mid 80-400hz.

Simulations for lowmid looks really bad, but now i have kind of phasey bass section and i dont like it.
i have to try this thing, it looks similar to whats simulation says on bass.

i hope i can call the phasey away tomorrow

Nothing special going on here, just changed shelf filtering to PEQ and phase curve got little bit better, upper graph is steep linear phase and lower is 1st bessel, window is 2ms. measured over listening spot couch.
wavequidos seems to bend phase a little bit.

These two are best xo´s i have worst is LR2, LR4 ain´t to bad either.

I had forgotten how your setup had evolved. It's looking very similar to what I'm thinking: TPL-150H above 2kHz, a cone-driven horn from somewhere in 400 to 600Hz in a wide horn, dual 10" midbasses side by side below the horn, and separate subs.

Which JBL Cinema horn are you using? Is it 6.5" or did you adapt it to the FST? BTW, I have FSTs in my B&W speakers and like them very much. And I might need to venture into phase plugs to extend my 5" Faital midranges a bit.

Lots of similarities between the projects!

quido is from 3730. i have plans to evolve that wedge style phaseplugs, easy to fit with fst.
upper graph is steep 90-150db/oct 420-2200hz, that round phase plug helps that 2k area, tpl crossed @2k phase rises little bit more.

Haut-parleur PHL Audio 1500Nd-SQ, 8 ohm, M17Nd, charge arrière close
this has been on my mind too, but i dont need any more db to midrange. fst runs now -6db below others!!!

amp gains revisited

old: low lowmid mid high
29 26 22 22
pre 0 0 -5db 0

new: 25 22 22 22
pre 0 0 0 0

tpl´s got 3,3ohm serial resistors and fst´s 7,5ohm, thats -4db to tpl and -9db to fst.

-4db overall to dsp noisefloor, hiss from dsp is now much better.
