Really Need help on this...1.2 @ 35hz?

[itzme218 10+ year member]

Ok so I'm trying to build a 1.2^3ft @35hz. with a 3" port. Inputting numbers into the RE calculator. Can't seem to find a f'in way to do it without external port or wasting internal vol.

And yes this is what pioneer recommends. Well they rec. 1.2^3ft with a 3" port.

Max: 1.6^3ft

Anyone know of some other calc that I can use to calc slot port and not L port...maybe that will help

Is the port sloted or round ? Either or there is some information missing in both cases.

It was a circle port. They recommend 1.2^3ft after sub displacement with a port of 3"x 3.5" and this turns out to be about 50hz...WTF

i got 10.75 straight or 11.75 flared

All three are tuned really high about 52/53hz. Box vol is after displacement of sub woofer, but i'm not sure if its after port displacement. Either or its still tuned above 40hz yeah?

i have no idea why they would recomend tuning that high for daily
