[QUOTE="ThirdCoastS-10, post: 1929514, member: 557199"] 9. Why don't you recommend vented enclsoures for the RL-i series? Simply stated, because the Premium series is geared better for the job. The RL-i Series is certainly capable of being used in a vented application, however ported enclosures cause the driver(s) to absorb more power from the amplifier, thus the risk of thermal failure is greater on the RL-i's 2" voicecoil with respect to the RL-p's 3" voicecoil. The RL-i's Qt parameter is also not optimal for vented enclosures, optimal being a Qt of 0.4 or less. If you are a responsible listener however, you should have no problem implementing a vented design for the RL-i Series and may use the following guidelines. Please remember that burned voicecoils are not covered under warranty and one should not use more than 300wrms on a ported RL-i series driver. RL-i10: 1.8 - 2.5 ft3 tuned to 25 Hz with a 4" x 20" long vent. RL-i12: 3 ft3 tuned to 22 Hz with a 4" x 20" long vent. from the SS site.... [/QUOTE]
