im modeling the box ive biult to try and get ahead start on what i think ill have to do to it to fine tune it. currently it sits at roughly 18-18.5 ish with subs in has 41x5 port thats24'' long comes out the baffle 4.5'' over all the box is 48x44x25.5 sides, bottom, and port are 1.5'' and...

From soundwesthost: "The maximum delay is 55ms at around 18Hz. Although this may seem to be "bad", it is actually a very good result. A similar delay at a higher frequency could be very audible - depending on the frequency. Group delay …

The audible threshold for group delay is about 30 milliseconds, although lower is desirable. WinSpeakerz calculates group delay to let you know if your design is within the desired range See Figure 4 for the Titanic system group delay (blue plot). As you can see, our example has a maximum group delay at 23 Hz of 9.2 milliseconds. Phase Response

Group Delay is directly related to the change of phase of a driver as it rolls off -- usually referring to the roll-off at the bottom of a woofer. The higher the order of the roll-off, the greater the Group delay. A flat curve would be best, but would require a speaker to be flat to DC. It's not going to happen.

This would imply that the group delay of a 50 Hz closed box system would be inaudible. Leach's differential delay works out to be about .475 cycles (or 9.5 ms) for this system at 50 Hz. Using Leach's differential delay makes the delay appear worse than if you consider group delay alone.
Group delay and phase delay - Wikipedia
https://en.wikipedia.org/wiki/Group_delay_and_phase_delay
In signal processing, group delay is the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay, in contrast, is the time delay of the phase as opposed to the time delay of the amplitude envelope. All frequency components of a signal are delayed when …

It is generally accepted that group delay should ideally be zero seconds at all frequencies; this is where the use of an advanced digital signal processor (DSP) comes in, to attempt to at least ‘align’ groups of speakers in a multi-way system in the event processing is not available to you to make time adjustments per cycle.
Time Correction - Hybrid Audio Technologies

Group delay is impulse response over time. Group delay increases significantly at low frequencies and is considerable in larger midbass and subwoofers. An excellent use of time correction would be to delay the smaller Legatia midranges and tweeters with respect to the larger midbass and subwoofers so that the low-frequency delay of these drivers is synchronized in the time …
