B&C 15NDL76 15" Neodymium Woofer is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great Full Range Driver!Replaced 4 heavy magnet jbl type 2226 15's with 4 B&C 15NDL76 15" Neodymium drivers for my 2 PA. mains. I was totally impressed with the smooth, clear and punchy sound. The bass thump was "very good", and at 10lbs. each compared to 25lbs., I dropped 30lbs. on each cabinet.

B&C 15NDL76 15" Neodymium Woofer

What size box ,sealed or vented & if so what size port ?

Asked by: djduane
This driver will perform well in a ported enclosure of approximately 4.0ft³. Two ports 4" in diameter, basically just holes in the box of 3/4" material will tune the enclosure to about 56Hz, with an F3 of approximately 53Hz.
