What is the recommended ported (bass reflex) box volume for Dayton Audio PN395-8?

According to electroacoustic alignment calculations, Dayton Audio PN395-8 performs optimally in a 71.4 liter vented enclosure tuned to 47.6 Hz, reaching an F3 cutoff of approximately 46.9 Hz.

Can Dayton Audio PN395-8 be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 31.4 liters with a Qtc of 0.707, the system exhibits an F3 of 87.0 Hz with tight transient response and natural roll-off.

What port dimensions should be used for Dayton Audio PN395-8 to avoid port chuffing?

To keep vent air velocity below turbulence limits at rated power, a minimum port diameter of 12.5 cm with a length of 13.8 cm is recommended.
