THIS IS A DIGITAL COPY OF A SET OF ORIGINAL AND VERY RARE 1958 BLUEPRINTS/PLANS FOR THE FAMOUS JBL C40 HARKNESS LOWBOY REAR-LOADED FOLDED HORN. 4 PAGES OF BLUEPRINTS INCLUDED MEASURING 24” X 36” EACH. THESE DIGITAL COPIES ARE FROM THE ORIGINAL 1958 PLANS AND SINCE THEY ARE DIGITAL COPIES, NO DEGRADATION DURING REPRODUCTION EXISTS ANYWHERE! SIMPLY DOWNLOAD THEM TO YOUR COMPUTER OR FLASH DRIVE AND THEN EMAIL THEM TO YOUR LOCAL STAPLES OFFICE SUPPLY STORE WHERE THEY HAVE THE EQUIPMENT TO PRINT THEM OUT ON BLUEPRINT PAPER OF THE SIZE NECESSARY. THESE PLANS ARE A MUST-HAVE FOR THAT PROJECT YOU HAVE WANTED TO UNDERTAKE WITH YOUR SON OR GRANDSON, DAUGHTER OR GRANDDAUGHTER. EVERYTHING YOU NEED TO BUILD YOUR OWN SET OF BEAUTIFUL AND LEGENDARY JBL C40 REAR-LOADED FOLDED HORN SPEAKERS. OR, YOU CAN TAKE THE BLUEPRINTS TO YOUR LOCAL LUMBER YARD/WOODWORKING MILL AND HAVE THE PARTS MILLED THEN MERELY ASSEMBLE THEM YOURSELF. MAKE SURE YOU USE ¾” BALTIC BIRCH PLYWOOD FOR THESE SPEAKERS AS THIS WOOD IS KNOWN AS BEING THE BEST FOR THE TRUE-TO-LIFE REPRODUCTION OF HARMONIC FREQUENCIES INDICATIVE OF THE FAMOUS JBL C34 AND C40 REAR-LOADED FOLDED HORN. YOU CAN ALSO BUILD A SET OF C34’S WITH THESE PLANS BY ELIMINATING THE LEGS, STAND THEM UPRIGHT AND ATTACH A 2” BOTTOM STAND. THESE 1958 JBL PLANS MAKE A PERFECT GIFT FOR THAT SPECIAL AUDIOPHILE IN YOUR LIFE! CHRISTMAS IS COMING! DO YOU HAVE SOMEONE IN MIND? NOW IS THE TIME. THESE .PDF FILES ARE TOO LARGE TO POST ON AUDIOKARMA.COM SO I HAVE PROVIDED YOU THE LINK TO MY GOOGLE DRIVE WHERE THEY ARE STORED. THESE PLANS ARE FREE FOR YOUR ENJOYMENT!
