Thank you everyone for all your help. I do have another question. I had the focal ps165fx3 and have tuned them multiple times with helix mk2 and everything went well. But the last time my tweeter blew and I think it might have to do with the reference curve offset but not sure. I was using auto eq and it blew halfway while tuning the tweeter alone. Any ideas what could have caused this?
Recommend you get a 47 microfarad capacitor to protect the tweeter from unintended frequencies. Then regardless of any accidental signals from the DSP/amp, your tweeter will be protected. Put it inline on the positive side of the tweeter.
47uF 100V Electrolytic Non-Polarized Crossover CapacitorElectrolytic non-polarized (bi-polar) capacitors are perfect low-cost solutions for use in passive speaker crossovers. These capacitors feature axial leads, a 5% dissipation factor, and are rated at a 100 VDC working voltage which equates...
Thank you I'll try that too. Do you know about the helix dsp mk2 measurement curve and reference offset in the rta tab? The reason I'm asking is because that was the only change I made tuning it this time aroind
I have the helix p six dsp so I know what you’re talking about. Yes, I think it’s definitely possible when using auto-EQ to set the target too high relative to your measurement offset and blow something. (The helix even puts up a warning message about this possibility when doing auto-EQ)
I agree with the prior post on the capacitor to protect the tweeter.
I've have blown a speaker once before and it smelled like an electronic burn. This time it had no smell or sound. In the middle of running a rta sweep the tweeter just stopped working. The high pass crossover was set twice the given fs level. Factory fs is 1500 so I set it to 3000. I have the low pass bypassed altogether.
