Product Details

B&C 8BG51 8" Neodymium Woofer

B&C's 8BG51 8" neodymium woofer is fitted with an optimized paper cone and rubber half-roll surround, and strikes a fine balance between bass output and overall efficiency. The 8BG51's ventilated voice coil gap ensures long term power handling and reduced power compression, and a copper cap on the pole piece reduces high frequency-degrading inductance. Highly recommended for compact 2-way speaker systems.

B&C 8BG51 8" Neodymium Woofer
B&C 8BG51 8" Neodymium Woofer is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Premium Driver For Line ArraysWe use these as our premium driver for our line array cabinets. They have good power handling and extension. The octagonal basket makes them quite sturdy and easy to mount close together in a multiple driver alignments. This driver is articulate and clean even when driven hard. It also has ability to deliver a level of clarity in the vocal range that we have found in few other drivers.

Rated 5 out of 5 by from Great speakersThese are the best speakers I have used to date ,the problem is ,I like to flush mount the speaker to the cabinet face but the rim design makes it impossible for me as a hobbyists to do .I would suggest that The boys at B&C redesign the frame to a round configuration also there are casting marks on the frame which makes them look cheap. I believe a speakers should look as good as they sound .

B&C 8BG51 8" Neodymium Woofer

Will it work good sealed

Would this driver perform well in a sealed enclosure playing down to 50hz (car audio application)? I know it works in a ported box but it will be tricky getting the recommended amount of cubes and the port length in an odd shaped enclusre.
Asked by: fyalinks
Yes you will be able to get 50 Hz from this sealed but probably not much lower. In a car application this should be relatively easy.
