Impedance and Phase Plots

Hi everybody.

I'm still working on my design here. Working in Vituixcad 2 running simulations.

Here is a 2 woofer 2 mid range bass reflex cabinet design.

I have posted the impedance and phase plots here, and would like some feedback.

Minimum impedance is 3.24 ohms at 153 Hz.

My questions are:

What would the nominal impedance of this cabinet be?

Are there any issues with phase?

My amp is a two ohm capable class D. Is this a safe load?

It is safe, but lots of amps would sound weak in the bass as a result. This is what commercial speakers call "discerning" of amplifiers.

This amp is a Mesa d800+. It's rated by the manufacturer at 400 watts into 8 ohms, 800 watts into 4 or 2 ohms.

At 10% distortion mind you. So more likely 300/600 reasonably clean.

B&O Icepower 700 S1 module equipped if I'm not mistaken.

I can say however that it will generate a ton of spl with a good cab.

But that's a topic for another thread.
