ALPHALITE™ 6A-CBMR Neodymium Series
Lightweight Neo 6.5” Closed Back Midrange for PA or MI use. Great in Bass Guitar rigs.
Please inquire about alternative impedances.
Multiple units exceed published rating evaluated under EIA 426A noise source and test standard while in a free-air, non-temperature controlled environment.
The average output across the usable frequency range when applying 1W/1M into the nominal impedance. Ie: 2.83V/8ohms, 4V/16ohms.
Eminence response curves are measured under the following conditions: All speakers are tested at 1w/1m using a variety of test set-ups for the appropriate impedance | LMS using 0.25” supplied microphone (software
calibrated) mounted 1m from wall/bafe | 2ft. X 2ft. bafe is built into the wall with the speaker mounted ush against a steel ring for minimum diffraction | Haer P1500 Trans-Nova amplier | 2700 cu.ft. chamber with
berglass on all six surfaces (three with custom-made wedges)
