BASSBOSS Questions
I have a question regarding heat. Not the heat generated by the driver motor, but in the environment. When it's summer and over 100 degrees out I'm guessing I'll need to take precautions and set things up differently. I'll likely have most shows I do either indoors or at night, but this won't always be the case, so let me know what this will mean for use.

I'm guessing that since it has thermal protection it will keep things within reason, but does this mean it'll just operate at a bit of a lower output when it's blazing out?

Heat is always the enemy. The amp in the ZV18 doesn't tend to get very hot but if the amp plate is left in direct sun in the summer it would double the problem. Keeping the amps shaded would be a good idea.

Only 2 to 8% of the amp's output is converted to heat, so its cooling requirements are low. If it does get hot enough it will reduce output to prevent overheating. If the heat continues to rise after the level reduction, it will shut down. Fan cooling can be added if that becomes a problem. The air movement generated through the ports helps to cool the amp so I don't expect running it harder will cause it to overheat more. So far I haven't been able to get the amps above barely warm.

Please let me know if there’s anything else I can clarify.

Hey David,

Thanks for your reply. The heat thing though wasn’t a question about the amps, as i realize the efficiency of the Class D setup negates most issues that would occur otherwise. I’m asking about running the drivers hard in the heat. I have felt the magnets on a few subs after a hard session and they can seriously heat up. I figured the porting will help with this quite a bit normally, but if ambient temperatures are significantly high is where i was curious.

thanks,
Glen A.

Hi Glen,

Ambient heat will affect how well the drivers cool but there's not much to be done about it, other than turning the system down, that will reduce the operating temperature.

Amps run 90 to 98% efficient, meaning 2 to 10 percent of the energy is waste heat. Woofers run 1 to 4% efficient, meaning 96 to 99% of the energy going into them is converted to heat, the remainder into sound. Heat is the enemy, more so in the voice coils than in the amps.

We have to limit the inbound power to prevent excess heat buildup but ambient temperature will change how long they can be run at maximum output. If the limiters are set for high-temperature conditions, then max levels in cooler temps would be compromised. Normally we expect things to be pretty hot so even in the desert heat, you should be OK, just remember that you do have control over the level. Thinking of the volume knob as a 4 percent sound a 96 percent heat knob would be informative.

Thanks for the great questions!

Hi David,

Ahh, good to know more about the motor efficiency… I was thinking about the coils. I’m certainly not expecting max levels and will totally think of the volume as a heat knob. I just wasn’t sure how much the protections could do for that and how much i needed to keep an eye out.

thanks!

Glen
