This is the second installment following the progress rebuilding our KV2 ES system. Containing the very first production unit of the ES1.0, this system needed to be brought back to factory spec and cosmetic appearance. Having Stripped the ES1.8 subs in the first part of our blog, this part shows the ES2.5 and ES1.0 cabinets stripped back before we begin the re-build.
The next step for the KV2 restoration was the ES1.0 mid-highs. Compared to the ES1.8 subs, these were in much better condition. Not surprising as they have been in the air rather than the subs which had been on the floor of a venue for a very long time. Issues with them include rusty metalwork, poor exterior paint finish to the woodwork, several damaged bolts for the waveguide sections and internal damping material soaked in the remains of smoke machine fluid. The waveguide sections needed to be removed by taking all button head socket head bolts out. This allows the whole waveguide section including both 6.5″ and 1″ drivers to be removed in one go. Once the waveguide is out, the 12″ LF driver is revealed along with all of the smoke fluid soaked damping material.
Once all exterior components were removed from the ES1.0s, the insides were inspected. This revealed the fibreglass internal damping material was soaked in smoke machine fluid. This needed to be replaced, but the original pieces were carefully removed and retained to be used as templates for the new pieces to be cut from. Lastly the low mid drivers were taken out, leaving the cabinets bare apart from the connector plates, which wouldn’t come off without being damaged. As one of these boxes is the first ever production unit of the ES1.0, serial 000001, the serial number on the original connector plate is a significant part of this system and we thought that it was better to leave the plates in place and mask them off when it came to painting.
