Product Details

B&C 6FHX51 6.5" Professional Coaxial Speaker 70 x 70 8 Ohm

B&C's 6FHX51 6.5" coaxial speaker offers pro-quality performance and a compact footprint. Point source loudspeakers offer improvements in overall coherency thanks to optimized driver alignment.

The 6FHX51's ceramic motor (woofer), polyester diaphragm neodymium HF driver, and FEA-optimized design produce high output and low distortion. In addition to the superior articulation and accuracy of coaxially aligned drivers, the 6FHX51 requires very little baffle area compared to separate LF and HF components.

Is there a pre-designed crossover i can buy with this speaker.  Basically looking for a plug and play with high quality sound.  I don't know how to design a crossover.  Or, would be willing to pay someone to design one for me.
