Need help understanding DIY subwoofer amplifier power requirements.
Hi first of all, I’m a novice on the topic willing to learn. I noticed that for diy subwoofer high-powered amplifiers are used. At high level analysis, My understanding or assumption is, to compensate the DSP applied (ie a -6 db at 90hz with a q of 1) lo flatten the frequency response at 75 db you would need more power to get to the original 81 db.
i.e. originally 81 db required 100w ( i know, very inefficient, its just hypothetically)
75db 100w -> 78db 200w -> 81db 400w
can some one confirm or deny or enlighten me?
