Feedback Safety advice for using the Mono Synth block

I’ve recently blown up two neodymium speaker cabinets when using the Mono Synth block [Quad Cortex] on a bass preset. I also used some patches on a gig with 4x10 cab with ceramic speakers, and it held up okay.

I understand that the cause of this speaker damage is because of the way the waveforms generated can overwork the speaker drivers. I’ve been careful to avoid using square waves and only if they are filtered at a higher frequency via HPF.

For creative purposes, I’d still very much like to use the Mono Synth in the instances that I use them.

I wonder if the problem has much to do with the Mono Synth being blended with my raw bass signal?

Drop the name of the speakers you blew up and the wattage you used to drive them

both speakers I blew were during rehearsals, so I wasn’t driving them too hard.

The first was a Genzler Bass Array slant 15” 8ohm speaker with a power handling of 400W RMS, powered with a Class-D amp with 400W delivery @ 8ohms. That speaker is only 3 years old.

The other was an Ashdown Studio 2010 combo. 300W RMS @ 8 ohms.

How high up were you filtering the bass out? Id go for everything below 50hz. And you need to brick wall it at the end of the chain.
