Eminence Beta 10 CBMRA

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

The compression driver should be around 40 years old. It offers a 2.5 inch voice coil if I remember correctly as it is a midrange compression driver. The Frequency Response of the compression driver is 300 Hz – 3 kHz at its rated wattage although, with the horn it can reach to around 8 kHz before a heavy decline in the frequency response. 

As it was much faster to just piggy back the input of the compression driver amplifier to another amplifier using the Eminence Beta 10CBMRA loudspeakers, I just lowered the crossover point from 250 Hz to 200 Hz. No, the 250 Hz setting is not aimed towards Home High Fidelity. That is setting I used on that compression driver/horn for sound reinforcement before retiring it in early 2000 and buying EAW KF 750s.

The amplifier used to power the compression driver in the youtube video is a Crown Powerbase 2 and, the amplifier to power three Eminence Beta 10CBMRA loudspeakers was one channel of an AB Precedent 600 (First Generation).

Best Regards,

	The amplifier for the Eminence Beta 10 CBMRA arrived 20 minutes ago. The PV 2600 will feed each driver 450 - 500 watts from 125 Hz on up. I am planning to pick up another 2600 and 3 more Eminence Beta 10 CBMRA totaling 8 drivers possibly in a week or so. I will keep you updated. Best Regards,
