This subwoofer works well for both sealed and ported leaning slightly more towards sealed. The following are recommendations based on 250 watts of RMS power. Great for tight places such as under the seat or a custom console install.
.5 Cubic Feet Sealed:
This size will give you a resonant frequency of 59Hz to 64Hz. Very pronounced drive with less sub-bass extension. 3dB down point of 49Hz.
.7 Cubic Feet sealed: (Recommended)
This size will give you a resonant frequency of 52Hz to 57Hz. Optimum for both SQ and overall output. Very smooth with a -3dB down point of 45Hz.
.9 Cubic Feet sealed:
This size will give you a resonant frequency of 46Hz to 50Hz. Stronger sub-bass extension with a -3dB down point of 41Hz. With this box you are at full excursion at 250 watts RMS.
1.2 Cubic Feet ported: (Recommended) (Port) = 12.56 square or 4” round by 15” long. This size will give you a resonant frequency of 47Hz with a 3dB increase over sealed. Sub-bass extension is good but also gives a very hard-pounding bass. Will perform very strong and broad range for a shallow subwoofer!
NOTE: 50% Poly-fill/Dacron was used for all box specs given.
