Iteachstem Posted December 18, 2020 Share Posted December 18, 2020 I wanted to document my upgrade process for those of you who wanted to take the tinkering/budget approach to installing the B&C DE 10 driver into your KLF20/30 etc. speakers. Feel free to ask any questions. I purchased these drop in fit drivers for $36 plus tax on ebay: https://www.ebay.com/itm/2-Paudio-PHT-409-Horn-Tweeter-Supertweeter-Klipsch-replace-K-79-K-75-K-76-K-84/372632527011?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 And the B&C Drivers: https://www.parts-express.com/bc-de10-8-1-mylar-horn-compression-driver-8-ohm-2-bolt--294-600 Then, I disassembled them as you will only use the horn parts. Remove the disc and cut out, dremel, sand, etc. these center phase plugs according to the pictures. The B&C Drivers already have a phase plug inside the housing. That concludes the modification of the lens assembly. Quote Link to comment Share on other sites More sharing options...
Iteachstem Posted December 18, 2020 Author Share Posted December 18, 2020 Next, I bought some bolts and washers to mount the B&C driver to the horn. ...and assembled the unit to test fit everything... Then, I mounted the horn... and then align and attached the driver. Do not over tighten. and connected the wires. (You need to cut the OEM connectors off and replace with larger ones) Final picture: Cheap horns about $40 B&C Drivers about $100 Misc. parts less than $10 I hope this was helpful! So, for about $150 you can have a great upgrade to your speakers! 1 1 Quote Link to comment Share on other sites More sharing options...

Iteachstem Posted December 18, 2020 Author Share Posted December 18, 2020 If anyone out there doesn't want to do all of the work, I have an extra set (Brand new) I built that I will sell for $175. Pick up in the Western Burbs of Chicago. 60511 1 Quote Link to comment Share on other sites More sharing options...
