Softening a huge speaker , a low efficiency one

[stormwalker100]

....ITS SUPPOSE TO BE STIFF lol its a P.A. type driver its made to be punchy and still handle mid bass well

[Max1636]

Not that it matters when doing this but you have your polarity backwards

[kel1981]

So this method is to run the speakers in?

[chrisbx1975x]

if that's the case then correct your first comment, don't talk to me about it.

[ReiMomo]

Everything is correct.

[chrisbx1975x]

his process is fine.

[chrisbx1975x]

it has two ports, it should be ok.

[ReiMomo]

A ported box will reduce excursion especially at box tunning frequency.

A sealed box is the opposite.

[ReiMomo]

you should use around 25 Hz on free air.
