Suggested cabinet volumes are between 7 and 15L. The latter yields a Butterworth alignment with a bass system resonance of 50Hz and a frequency response that is -3dB at 50Hz.
Suggested cabinet volumes are between 10 and 25L. The latter yields a Butterworth alignment when tuned to 29Hz with a 2″ ID x 10″ port. The frequency response of this alignment is -3dB at 30Hz.
Measurements and Example Crossover
Our Custom Seas L18RNX/P woofer was installed in a sealed enclosure and a passive crossover was designed for an acoustic 2nd order LR low pass transfer function with a crossover frequency of 2KHz. This is a great transducer for a 2 or 3 way bookshelf or tower speaker crossed over to a midrange from 100 to 750Hz or a tweeter at 2 to 3KHz.
