Hi,
I'm building a subwoofer and have a plate amp (DAYTON SA240 240W SUBWOOFER AMPLIFIER). There's not a lot of documentation on this thing.
One review says "A built-in “rumble filter” attenuates the lowest audio frequencies to help conserve amplifier headroom and protect drivers. The “rumble filter” is actually a 12 dB/octave high-pass filter that is centered at 20 Hz, the F3 is 18.2 Hz. Since most source material does not contain information below 20 Hz, usually we are not missing anything. But, in cases where information is available this low, we generally need to protect our drivers from this potentially damaging information. Since excursion demands increase with decreasing frequencies, even the beefiest sub can start to run into overexcursion problems. This is particularly a concern in vented subwoofer systems where overexcursion occurs rapidly below the tuning frequency."
I'm having trouble determining whether this thing has any sort of a high-pass equalization filter that I can use in my box calculations. If it does, does anyone know how exactly would I figure this into my WinISD Calculations.
Thanks!
Greg
