Yes, vituix CAD does this. Mixed impedances are handled without issue
This will be the HF driver I am designing the rest of the speaker around. I’ve heard it in person in one of the pro audio manufacturers products Ive used regularly and it is quite simply outstanding
The in room transient response waterfall graph and unbelievably low distortion/breakup even when driven really hard make it far superior to other traditional HF compression driver design in a way the on paper specs dont fully show

Im kind of reviving my so called ‘soundstage 215<span class=””><span class=””>’ project. Started a separate post thread for it with more detail</span></span>
Bumping this to bring more attention to it as may have got missed and looked over during forum move and prior spam post flooding
Its one part of a really important umbrella topic that is amplifier specs that a lot of people need to gain better understanding of to get the most out the equipment they are spending money on
Another path of attack could be unscrewing the terminal plate and seeing if any pins/clips are visable going through the front panel
Depending on the adheasive type used some IPA may help release it
Not a hard reccomendation more something to consider
Can you remopve the back panel on this or is it fully sealed?
My studio monitors have a decorative plastic surround covering driver screws that snaps in with a few tabs that are hot glued in place on the inside, if i need to remove a driver I just unscrew the back plate, free the tabs and pop the plate off
I thought the epics had 2 PR per speaker so one each side of both speakers?
Adding my own path of experince to this as its quite different to most in the DIY audio space
I became fascinated by the 3 sciences and music technology as subjects in high school. College I studied music tech, physics and psychology then went on to do a degree in theatre and live performance technology with my dissertation subject being psychoacoustics in sound design. Now working professionally as a live sound engineer I have continued to widen my knowldge on low frequency control, electro acoustics (physics of microphones and loudspeaker drivers) and the psychoacoustic response to sound as specifc area of interest
As a result I dont have any guides or resources I would be able to share on here not because Im trying to guard any ‘industry secrets’ but due to where my combined knowldge has been aquired. I will always be very happy to answer (often in high detail) any specifc questions you may have though
youd use 4 ohm
speaker impedance matched or higher than amps impdenance config is safer than the other way round
The impedance changes wildy across the frequency range dependant on driver behaviour and corssover design, the total speaker rating just gives an indication of the nominal or average imdenace overall
I found a forum post from the PSA designer saying the final measured impenace of theirs was around 4 – 5 ohms. Spec sheet saying 4 is just rounding to a nice number following the standard categories of 2,4,8 or 16 consumers are expecting to see
drivers wired to present 5.33 ohms to amplifier
Rough coffee break ‘napkin math’ crossover result
I will not be sharing component details publically on the thread at this time
yes 8ohm model with diaphrams in parallel is 4ohm load
depends which model you use, the dcx464 comes in 8 and 16 ohm versions
