JBL 4888 Line Array - LOAD IN- Cone Water Proofing 

Installing some brand new 12LW1400 from my favorite speaker manufacture Eighteen Sound. Waterproofing Speaker Cone, simple and secret. After this upgrade the speaker new program rating increased to over 3000 watts.per cabinet......thats what I'm talking about. Changing out crossovers to match new speakers also....in a later video.
