    Hi everyone. I have some questions about port length.
    I found this:

    HTM-12 - 3" (tuning ~45hz) *On new 2020 design use ports at full length without cutting. How long is “full” length??

    Also, Could someone tell me the port length for the HT-12? I found the HT-10, but not 12.

  2. If you have the ports with the flare on the inside they do not need to be cut (not sure if they ship with these yet).

    If you have the ports without the flare they should be cut to 3" for the HT-12, or 4" for the new HTM-12.
