Dubwoofer's Tuba HT build

[Bill Fitzmaurice]

I had my voltmeter connected as I demoed the Tuba to a friend. If I had to guess, last night I was probably pushing about 35 volts

35 volts isn't going to bother anything per se. It's well below the driver Pe and Xlim, and chances are that there's not enough content at 20-25Hz for it to be reaching xmax either. I just say limit at 28v if you have a limiter as there's very little to be gained by running hotter than that.

Difference between 28V and 35V: 2.5dB

If you need more low end, build another. +6dB.
