What I have found with other brand Class D amps is their 800 watt models seem to be equal in output volume as other class AB style amps of 450 watts or so.
I don't know why.
Do they use FTC ratings ?
Again, no one in Vegas has any Ampeg's amps to try or Demo.
From experience, Ampeg seems to be accurate with their ratings. IMO.
So maybe a 450 watt Ampeg 3Pro may be equal in output volume as a 7Pro into the same cab with same Ω rating?
I wonder if the other brand Class D amps actually use FTC ratings when publishing their ratings?
And if they don't use FTC wattage ratings, it may a good thing to implement so the consumer has a more unbiased and equal view of what they are purchasing.
I somewhat understand why Bass amp builders may not use FTC ratings over RMS..
I "think" FTC is continuous to a point and RMS is an 'Averaging" with peaks over time?
A Standardization throughout the bass amp industry may be helpful and honest way to sell watts?
So coming back to the 3Pro vs the 7pro. Is it possible a 3pro non Class D amp be close or equal volume to the 7 Pro ?
