Attached is the group delay of the ported 38hz magnum in bold and the other line is the 20hz tuned passive. To me the higher group delay was audible in the ported version.

so the bottom end was all <sluggish> or phase funk, something wierd, ?

or was it just excessive and overbearing to the other speakers and sounds? as if it had crept up with more gain(not bad sound, just much of it maybe?)somehow?

Booger, I would describe it as the low bass thanks a little longer to build up to full volume and by that time it is behind the beat.

I wish I could have thought of that, very Well described! have you ever heard the opposite? Or what sounds like it maybe? tapped horn might be it, but don’t assume so because I don’t think it’s nit in other places too!!! A straight TL is a lot of things a bass reflex isn’t .. and a straight TL has a sound too. I’m
Not suggesting anything, but I am stating there is something to investigate as a group of people who have heard a variety of sounds and speakers.


I think i might be confusing , but I confuse myself too, lol!

Destructive or constructive interference are doppelgangers? But they have two types of twins. Identical or not. out past the obvious is the other and it’s gonna be a strange sound instead of flat out null or void... this is my best effort at abbreviating what I can’t technically say or could really if I tried?

Guerilla, I’m a hydrologist by trade but my hobby for 20 years has been speaker building. I believe that many things in life can be self taught. You could start by reading the loudspeaker design cookbook by v. Dickason.
