mga sir,
RCF L18-P300 is P22,800 each retail. discount depending on quantity.
we maintain and offer "dressed cone kits", not just voice-coil replacements.
The L18-P300 is one of the most used woofer in other brands.
TRIVIA: yung "inside-outside" voice coil was innovated by RCF more than 8 years ago, other manufacturers copied this concept a few years ago.
