Vintage KLH Model Twenty 20 Speakers, Rebuilt/Refurbished, Ready To Listen 1968




Item History & Price

Information:
Reference Number: Avaluer:51793192Model: KLH Twenty 20
Brand: KLHCountry/Region of Manufacture: United States
Original Description:
Up for sale is a 1968 dated pair of KLH Model 20 speakers that have been brought back from years of neglect.  These speakers internal parts have a shelf life and in order for them to work at their best, they need to be refreshed.
This pair came to me with (1) seized woofer and barely audible highs coming from the tweeters.  The cabinets looked like they had spent a few years in the desert resulting in a dry appearance.
After sourcing a correct 4 ohm replacement Model 20... woofer, the drivers were pulled out so i could rebuild the crossovers.  
Each crossover was rebuilt with Jantzen and Solen film caps.  The tone selector switch was cleaned as well.
Before the cabinets were closed up, each woofer was sealed with Mor-tite rope caulking around the frame to prevent any air leaks.  After they were tightened down, the surrounds were treated with liquid rubber (Acoustic Research's in-house blend) to help seal the cloth surround.
Now the woofers will push in but very slowly return to position.  
The cabinets were wiped down with a few coats of orange oil which really brought back the factory walnut veneer.  This pair has some exceptional figuring in the grain along the raised edges on the front.  It also has some water damage from a potted plant living on one speaker for many years.  Most of the damage is superficial (no air leaks) but the veneer has lifted/warped from it.  They also have typical scratches/dings and marks from 50+ years of use.  
For now, i decided not to address the grill fabric.  It has discolored from being in contact with the masonite board over the years but since they are hole free, its best to be left alone.  The fabric used on these is not easily replaceable so if its original, don't replace it.
There are no grill badges but that's how these came from the factory 

In regard to shipping,  Ill pack them separately with bubble wrap and hard sheet foam to ensure they arrive in the condition pictured.  

These are classic speakers that sound wonderful no matter what you power them with.
