The lower you tune the more decibels you'll lose as frequency increases, but the enclosure tuned to 20hz will still be able to play 80hz, or 100hz, etc, until you've exceeded the frequency band of the woofer, or your crossover point.

notorious97200 Posted January 17, 2018 Report Share Posted January 17, 2018 Regular ported box/wall are easier to tune, and to build. And they are more musical ? Why bother to build a 6th order bandpass wall ? What benefits ? black BMW X1 2.0 l 192 hp OEM head unit, Amplifiers : Audison AP 8.9 amp with integrated DSP and Ampere Audio 1200. Focal ES 100 K in front doors, and Dayton RS 180 for midbass under the front seats. 2 SSA DEMONS 10" subs, in a 2.6 ft3 ported box. SecondSkin Damplifier on front doors, and Luxury Liner Pro for the cargo area. Link to comment Share on other sites More sharing options...

That's exactly what I said. You just contradicted and then confirmed what I said in the same phrase. My Build Log Link to comment Share on other sites More sharing options...

You must not have understood it, because what I said is only a contradiction to your statement. You said "No, because if you tune too low you won't have any high bass.", which is wrong, because tuning low doesn't mean you won't have high bass. To simplify what I said, your output will decrease as frequency increases, but it is not drastic and it is very capable of producing higher bass notes unless you've reached a crossover point, or the woofer can not reproduce that frequency.
