Can one use his tl enclosures designed for 3134 with hpd315 and adjust the weight of the damping material?
case stays more or less same
because dimensions are dictated by driver Dia (TL cross section) and desired F3 of box (wavelenght)
so, for similar drivers, box is similar/identical
My idea was to build the TL assuming the use of a 15”… using a replaceable motor board and panel where the port is mounted.
That way I can also try my 12” and re-tune it accordingly.

It would be good if only the length of the port or diameter too?dimensions of final TL opening tube
dimensions, plural
so, both Dia of tube and Length can change
all practically depending of mood of actual operator of simulating software ................. in short - should I allow you use of PVC sewage standard dia pipe, or should I choose hardest to find non-standard Dia tube, thus increasing level of necessary efforts in making the boxes, resulting in perception of much higher sound quality and value of favor I made for you

that needs confirmation; taking actual box sim for 15" driver, and inputing data of 12" driver, then trying to vary TL tube and stuffing to optimize for 12"
but, don't hold your breath; in this moment I'm 3 (5 ....... 7......... 9.......... 12?) years late with things I want to do ..... just partially resulting from time spent to really keep up with things I must do
Had to ask to be sure 🙂dimensions, plural
150mm br port was pretty dificult to find locally so it will be of much higher sound quality actualy the highest 🙂
As for the favor.. can’t measure that one
Thanks!

Ah yes, now I remember.
The overall box dimensions on the MathCAD sheet for the 3149 were also slightly different…not just the port and stuffing.
EDIT: That must be why it was so easy to rationalize old GRF cabinets purchase 😉

I've told you ....... but probably not clear enough
standard sewage PVC pipe - OD is 160mm, wall thickness 3.2mm, resulting in ID of 154.6mm
close enough in my book, even without re-calc for difference of 4.6mm ....... which is 6% diff of area, hardly bigger than any of other variables in system
Yes you told but sometimes if you don’t take the most difficult road it seems you didn’t get there
Used may be eroded on the I.D. which will completely throw your tuning out of wack😉
Also, as a general guideline…you don’t want your speaker to sound (or smell) like $xxx!

The port I have has thinner wall, 1mm so my ocd started to work since yesterday 🙂wall thickness 3.2mm
Would a port with thicker wall better?
