Technical question: Skar sub box decision: Between 12" and 10" Skar ported on Stock HK sub

[Mbrigh3]

Good morning, a few of us have moved our HK 10" sub to Skar 10" ported boxes which seems to work very well. My question is can we use the 12" box with a 10" adapter ring and have the same outcome? The 12" is a smaller box in length and height but it has a bigger port. I'll list specs below. I'm leaning toward trying the 12" box because it would fit under the rear seat better as its .6" smaller in height and doesn't extend pass the 60% portion of the seat.

I know I can get an aftermarket system but I don't want to delete my ANC, so this is the best situation for me. Our stock sub is 204w 6ohm 10"

The specs for the 12:

Port Width	2.00"
Number of Ports	1
Total Box Volume	1.20 Cubic Ft
Number of Subwoofer Chambers	1
Tuning Frequency of Enclosure	38 Hz
Number of Terminal Cup Connections	1

Enclosure External Dimensions

Depth	17.50"
Height	9.40"
Length	36.00"

SPECS FOR THE 10"

Port Width	4.00"
Number of Ports	1
Total Box Volume	1.41 Cubic Ft
Number of Subwoofer Chambers	1
Tuning Frequency of Enclosure	41 Hz
Number of Terminal Cup Connections	1

Enclosure External Dimensions

Depth	18.00"
Height	10.00"
Length	46.00"

Sub is going to sound horrible in a box not designed for it. You should reduce internal volume by about 0.2 cuft and it will work

That would mean the 12" box would be better. Its .2 smaller then the 10" box. I have it on the 10" box currently and it does sound good compared to stock box. The 12" box is sitting in my garage which will be tested tom.
