HI Art+/-3dB, close enough for rock & roll ;^).
The deep notch at 180Hz is interesting, looks like the plenum and port output may be 180 degree out of phase at that frequency, usually that sort of dip would show up in the simulation. That said, Hornresp is assuming one port, but there are four, so the port's "pipe resonance" will not be the same.
Some interesting discussion in this thread:
If the ports are capped off (covered/stuffed), does that dip still show up in the response?
Cabinets are finished!
unfortunately with 4 ports there wasn't space enough and the pipes went against the cone baskets.
If the weather allows me tomorrow I will test the whole pa at high spl in free field and check if the dip disappear!
I need to assemble dsp blocks on my audia solo 8x8.
I would to insert rms compressor and peak limiters (not a real limiter but the same comp with 100:1 ratio and 0.1ms attack possibly) each channel.
The rig is:
sinbosen k450 4x450 at 8ohm for the 2 channel of dcx464-8
proel psw2600 2x1300rms at 4ohm for 2xrcfmb12n351-8 wired in parallel per channel
sinbosen fp14000 2x2400rms at 8ohm for 1 18115-8 per channel.
How I can adjust limiters in the dsp to have good performance and safety ?
this powersoft manual is xhaustive?
Thank you very much
