Bronze Member Username: HiphopanonymousPost Number: 12 Registered: 12-2003 | I've heard that type r's are not recommended for ported enclosures. has anyone else heard of this? what's the optimum enclosure for the type r to bring out its fullest capabilities? |

Gold Member Username: GlasswolfPost Number: 1252 Registered: 12-2003 | figure it by the numbers. get the TS specs for the subs. Efficiency Bandwidth Product (EBP) EBP = Fs / Qes 50 or less = best used in a sealed enclosure. 50 - 90 = flexible enclosure options. 90 or greater = best used in ported enclosure. |

Bronze Member Username: HiphopanonymousPost Number: 25 Registered: Dec-03 | alpine type r's measure in the 50-90 range. what do you mean by flexible enclosure options? build the box so the box can flex? i'm not sure. type r measures in at 68.4 ebp. help? |

Anonymous | type Rs work best in a 42 litre ported box with a 32cm long port. Check out www.alpine.com for full specs on their subs |
