What large drivers need to do well is to handle the first few problem areas (rim resonance, cone breakup, etc.) that are inherent in these larger drivers. If the driver does that well then I'd consider it regardless of the cone mass. The LF lumped parameter variables are pretty much irrelevant to me. DSP can handle anything down at those frequencies. The sensitivity is a major factor of course as it needs to be matched to the compression driver, although with an active DSP crossover this too is pretty much irrelevant (relevant in a passive crossover however.)

i confess, i have a perversion addiction to 12V stuff. I had to buy 8-out car dsp when i saw it too cheap.
i hook it up with couple partsbin car amps. Funny thing is this is quite nice, no noisy fans and hiss from compression driver.
Processor eats analog and opt, coax. hook it with cd and keep on going.
speaker wire is 7wire trailer cable just ad 1 more wire to hook all four drivers.
I took dual channel measurements, throw them to vituixcad and got nicely matching slopes.
current 4th order crossover wraps 900deg, its bit different than main flat phase FIR set.
im an addict

i have to tune tweeter slope a bit, its bit steep at the moment. fir suffers from floor reflection mid twe, i could get it flat with fir file
Do you (still) use the DE25?![]()

Borrowed faital hf108 to test in jbl horns. 0 and 45degs compared to bms 4522.
seems that 4k bump is coming from horn. 4 drivers tested and best has been allready sold b&c de25 🙂 story of my life.
gotta try some felt padding inside horn if it helps, might be throat opening angle issue
No, i got bms 4522

Europe got redcatts i wanted to try but seems to be 4ohm version. Id rather buy 8 or 16ohm version.
Havent seen nice new 1inch drivers.
Been listening this cheap car amp setup, it feels more bass heavy compared to fir setup.
There was audison virtuoso dsp on blackfriday sale, almost bought it. It can do fir. Dang it
