I get 111 mm long. A mm is't going to make a big diff.

A quick check suggests that CHP will work in Mar-Kel70, but that a slightly lower port tuning would be needed to optimize it (not much thou)

Hello dave,

"A slightly lower port tuning". How can I translate this in port dimensions ?
Longer ports, enlarged port surface ?

I am thinking of building Mar-Kel, increasing ports height, allowing for tweaking by addition of wooden pieces in the ports.
Is this way the correct one ?

Thanks for your advice

Excursion by default is at 1w in. I usually leave it there, Power ratings on drivers for home use are largely irrelvent so i don'y pay attention to them
