You can see from the photo the tweeter has damaged foam but it does not affect the function! The the bass unit, the coil is open circuit and all 4 units (brought two more spare) are due to the corroded connection at the flex wire to the paper cone. Thus this is not internal open circuit and thus I try to reconnect them using a wire as shown. After repair, the driver can be used without any issue!

JBL 4642A + Crown DSi 4000 tear down photos
Got these all at very good price back in March 2016! The amp and the subwoofer is used in one of a 70 seat cinema locally by government for film screening. All equipment are on auction due to relocation. Hope to hear more!

Got this B-stock only US$400 cheap from Harman on-line shop. Sound great for this amp! 125W x 8 channels. Good for 7.1, bi-amp, tri-amp use for home theatre or home audio etc…
No fan and this is really high tech! 1000W for a 1U box! This amp is good for studio use for quiet operation. Only issue is that it has no network connection and cannot bridge the output channels.
