3dmax+vray
the 3d-modeling is one of my real work.
That explains my confusion with the shadow around the exponential curves of the left and right sides of the horn waveguide. I stared at it long enough as it doesn't make sense.
You need to improve your 3-D modeling skill. Just kidding 😀
hi cka,
have a look at minidsp, its fantastic for active setup.
cheers

no way) for that project mini dsp is a joke
the dacs a simply crap
the digital part is crap too.
sorry.
sub-bass without any absobers of course
Why is that?
But damn that looks nice!
no need in absorber on bass unit
it can only decrese speed of bass
and if it is sub with active filtering there is no way it can produce midrange from port)

correct stuffing has minimal effect <100Hz and will just impede airflow to the port. Good luck with your project they are very nice looking boxes.

dac pcm1794 apergio h-cmos (10v outut)
amp for woofer LME49830 2 pairs of sk1530+sj201
amp for mid-woofer LME49830 1 pair of sk1530+sj201
tweeter amp - power follower 99 with 2ск1529 and 10uf output polyprop cap
midrange amp - power follower 99 with 2ск1529 and 100uf output polyprop cap
steped 8 chanel attenuator
the xover is my own work based on tas3108
11mhz clock(hello mini dsp with 3mhz clock)
44khz (that is realy important no resempling)
An externally hosted image should be here but it was not working when we last tested it.

sounds fine to me
for me like crap.sounds fine to me
there is no way it can sound normal if you already listend good quality dac and hi-end quality loudspeakers\amps
is there something new?I got one thing from this thread - sounds like there's lots of crap out there
🙂 in audio 80-90% are crap
about the minidsp
fs is too low
dac are build in
dac output is like in pc audio cards entry level
48khz only (suxx)
need to add anything?

Have any schematics for these designs? I'm always interested in improving things. My main issue with the Minidsp is the whole dac thing but for the money & ease its great for beginners like me. I did have a dac with a valve output stage working for a while but eventually killed it somehow, fried a component on the board I think. I will admit even through the passive crossover it sounded very nice, let me guess, valves are crap 🙂
