FOR MANUFACTURERS AND RECONERS
THE FIRST STEP IN RE-CONING IS TO GET EVERYTHING ORGANIZED. MAKE SURE YOU HAVE ALL YOUR SPEAKER COMPONENTS AND THE ADHESIVES YOU PLAN ON USING. DEPENDING ON WHICH ADHESIVE METHOD YOU PLAN ON USING FOR THE JOB, IT IS ESPECIALLY IMPORTANT TO HAVE ALL THE COMPONENTS READY WHEN USING THE INSTANT ADHESIVES OR THE EPOXIES. THE SOLVENT AND WATER BASED ADHESIVES ARE A LITTLE MORE FORGIVING WHEN IT COMES TO SPEED OF ASSEMBLY. NO MATTER WHICH YOU PREFER TO USE ACOUSTICAL ADHESIVES HAS THE PRODUCT TO DO THE JOB.
WE HAVE PUT TOGETHER THE FOLLOWING PRESENTATION TO HELP ASSIST YOU WITH YOUR OPTIONS AND HOW TO APPLY THIS TO YOUR JOB. AS ALWAYS, IF YOU ARE IN NEED OF ANY ASSISTANCE, PLEASE DO NOT HESITATE TO CONTACT US AT OUR TOLL FREE NUMBER. WE ARE THERE TO ASSIST YOU IN MAKING YOUR NEXT RE-CONE A LITTLE EASIER AND FASTER.
STEP #1 BONDING THE CONE TO SURROUND
BECAUSE IT TAKES A WHILE TO DRY, APPLY THE WHITE FLEXIBLE WATER BASED #WD-32 ADHESIVE TO THE LIP OF THE PAPER FIBER CONE. THEN PRESS THE CLOTH SURROUND INTO THE ADHESIVE. THE EXCESS WHITE GLUE CAN BE CLEANED OF WITH A DAMP CLOTH. YOU CAN ALSO USE #GA-422 ON THESE FIBER CONES AND CLOTH SURROUNDS. APPLY THE #GA-422 TO THE CONE LIP, PRESS THE SURROUND INTO THE ADHESIVE AND THEN SPRAY THE LIGHTNING TACK ACCELERATOR ON THE SURROUND AND IT WILL SOAK THROUGH THE CLOTH AND INSTANTLY SET THE #GA-422. IF YOU ARE WORKING WITH FOAM SURROUNDS AND POLY-CONES WE WOULD RECOMMEND YOU USE THE BLACK SOLVENT BASED #BC-32 WITH THE SAME PROCESS AS ABOVE. IF YOU ARE LOOKING TO SPEED UP EITHER PROCESS YOU CAN USE THE #GA-410 INSTANT ADHESIVE. YOU WILL NEED TO PREP THE SURFACE OF BOTH SURROUND AND CONE WHERE THE BOND WILL BE WITH POLY-PRIMER..

STEP #2 APPLYING DAMPENER TO SURROUND
APPLY THE WHITE #WD-32 TO THE SURROUND IN 2-3 BEADS AROUND THE SURROUND. THEN BRUSH IT OUT TO COAT THE ENTIRE SURROUND. THE ADHESIVE WILL DRY TO A NON-TACKY CLEAR FLEXIBLE SURROUND TREATMENT. THE #WD-32 IS FAIRLY THICK AND CAN BE THINNED WITH WATER. ADD A TABLESPOON AT A TIME AND SHAKE IT UP AND CHECK THE THICKNESS TO SEE IF IT IS THE RIGHT THICKNESS YOU PREFER. WE HAVE ALSO HEARD SOME OF OUR CUSTOMERS THINNING THIS WAY OUT AND SPRAYING IT ON TO THE SURROUND BEFORE GLUING IT TO THE CONE.

STEP #3 BONDING THE SPIDER TO THE VOICE COIL
FIRST DETERMINE THE POSITION ON THE VOICE COIL WHERE THE SPIDER WILL BE. ONCE THIS HAS BEEN DONE APPLY A BEAD OF #GA-422 ABOUT AN 1/8” ABOVE FINAL RESTING POSITION AND SLIDE THE SPIDER DOWN THE VOICE COIL INTO THE CEMENT AND ONCE THE SPIDER HAS ENGAGED THE ADHESIVE ROTATE THE SPIDER 180° WHILE MOVING DOWN THE FINAL 1/8”. THIS WILL HELP TO MAKE SURE YOU HAVE GOOD ADHESIVE COVERAGE. THEN PUT A FILET OF THE ADHESIVE ON THE TOP OF THE JOINT BETWEEN THE VOICE COIL AND THE SPIDER. TAKE THE LIGHTNING TACK ACCELERATOR AND LIGHTLY SPRAY THE JOINT. THIS WILL INSTANTLY SET THE ADHESIVE. REPEAT THIS ON THE BOTTOM OF THE ASSEMBLY AS WELL. IF YOU FEEL THAT THE #GA-422 IS TOO RIGID YOU CAN USE THE BLACK INSTANT ADHESIVE #GA-410 WHICH IS MORE FLEXIBLE AND WILL WITHSTAND HIGHER TEMPERATURES UP TO 250° F, USING THE SAME PROCESS AS THE #GA-422. THIS PROCESS CAN BE DONE IN LESS THAN 2 MINUTES. WE ALSO OFFER THE EPOXIES AS WELL FOR THOSE OF YOU THAT ARE MORE COMFORTABLE WITH THIS PROCESS. THE #GEP-110 5 MINUTE EPOXY IS AVAILABLE IN 50 ML MIX-PAC SYRINGES.

STEP #4 BONDING THE CONE TO THE VOICE COIL
PLACE THE VOICE COIL THAT IS ASSEMBLED TO THE SPIDER INTO THE FRAME OR BASKET. NOW TAKE YOUR CONE AND PLACE IT ON TO THE VOICE COIL. TAKE THE #GA-422 INSTANT ADHESIVE AND RUN A BEAD OF THE ADHESIVE AROUND THE JOINT BETWEEN THE CONE AND VOICE COIL ASSEMBLY. THEN SPRAY THE JOINT WITH ACCELERATOR TO INSTANT CURE THIS JOINT. NOW TAKE THE ASSEMBLED CONE, VOICE COIL AND SPIDER ASSEMBLY OUT OF THE BASKET AND RUN A BEAD OF THE #GA-422 AGAIN AROUND THE OUTSIDE JOINT OF THE CONE AND VOICE COIL, AND SPRAY ACCELERATOR ON THIS JOINT AS WELL. THIS IS THE FASTEST WAY TO ACCOMPLISH THIS ASSEMBLY. YOU CAN ALSO USE #GEP-110 EPOXY OR THE #BC-32 HEAT RESISTANT CEMENT, WHICHEVER YOU ARE MORE COMFORTABLE DOING IT IN THIS FASHION.

STEP #5 BONDING THE SPIDER AND CONE TO THE FRAME OR BASKET
NOW THAT YOU HAVE THE WHOLE ASSEMBLY PUT TOGETHER YOU ARE GOING TO ATTACH THE SPIDER AND CONE TO THE FRAME. WE RECOMMEND THAT YOU USE THE #BC-32 CEMENT. THIS MATERIAL WILL PROVIDE A VERY FLEXIBLE BUT PERMANENT BOND IN BOTH OF THESE JOINTS. APPLY A BEAD OF THIS TRANSLUCENT BLACK ADHESIVE ON THE FRAME WHERE THE SPIDER WILL BE POSITIONED AND A BEAD WHERE THE SURROUND WILL REST IN THE FRAME. LET THE ADHESIVE SIT FOR 2 MINUTES TO GET TACKY BEFORE DROPPING THE CONE, VOICE COIL, SPIDER ASSEMBLY INTO THE BASKET OR FRAME. THEN PRESS THE SURFACES OF THE SPIDER AND SURROUND INTO THE ADHESIVE. THIS WILL TAKE ABOUT AN HOUR TO CURE. IF YOU WANT TO SPEED THIS UP YOU CAN USE A HAIR DRYER TO CURE THE ADHESIVE IN FIVE MINUTES. IF YOU ARE HAVING PROBLEMS WITH SPIDERS COMING LOOSE OR YOU WANT TO SPEED UP THE PROCESS YOU CAN TRY THE #GA-410 INSTANT RUBBER TOUGHENED ADHESIVE ON THIS JOINT. PUT A BEAD ON THE FRAME AND A BEAD ON THE SPIDER AND LIGHTLY PRESS THIS INTO THE FRAME. THEN SPRAY ACCELERATE ON TOP OF THE SPIDER ABOVE THE ADHESIVE. THE LIGHTNING TACK ACCELERATOR WILL WICK THROUGH THE SPIDER TO QUICK SET IT.

STEP #6 BONDING THE VOICE COIL LEAD WIRE TO THE CONE
WE RECOMMEND THAT YOU USE THE black Rubber toughened instant adhesive #GA-410. PIERCE THE CONE WITH TWO SMALL HOLES AND PASS THE LEAD WIRES THROUGH. SO THESE DON’T VIBRATE WHEN THE SPEAKER IS IN USE PRESS THEM TO THE CONE AND COVER WITH A BEAD OF THE HP-4000. EVEN THOUGH THE #GA-410 IS THICK YOU WILL WANT TO POSITION THE SPEAKER SO THAT THE SURFACE YOU ARE PUTTING THE ADHESIVE ON IS HORIZONTAL. ONCE YOU HAVE COVERED THE WIRES SPRAY THE ACCELERATOR LIGHTLY ON TO THE BEADS TO CURE THE ADHESIVE IN 5 SECONDS. THEN APPLY A DROP ON EACH WIRE ON THE OUTSIDE OF THE CONE AND SPRAY THIS AS WELL. THIS WILL PROTECT THE CONE FROM TEARING UNDER SEVERE VIBRATION.

STEP #7 BONDING THE DUST CAP TO THE CONE
Depending on the variety of cap and cone you are working on will determine which adhesive to use. If you are working with a paper or fiber cone to the same type of dust cap we would recommend you use the #Bc-32 nitrile rubber cement. You can use the white poly vinyl acetate #WD-32 ON THESE BUT BECAUSE YOU CAN HAVE HIGH TEMPERATURES BUILDING UP UNDER THE CAP YOU ARE BETTER OFF WITH #BC-32. ON POLY CONES AND CAPS YOU CAN USE EITHER THE #BC-32 OR THE BLACK INSTANT ADHESIVE #GA-410 WITH THE POLY-PRIMER SURFACE CONDITIONER. SWAB THE AREA IN THE CONE WHERE THE DUST CAP WILL REST AND DO THE SAME TO THE FLANGED AREA OF THE DUST CAP. Then place a bead of adhesive on the flange and lightly press and hold this in position. then run a small fillet bead of #GA-380 in the gap and spray it with LIGHTNING TACK accelerator to cure it.

STEP #8 BONDING THE GASKET TO THE FRAME
PLACE THE GASKET PIECES AROUND THE FRAME FOR HOLE POSITIONING PURPOSES. THEN PIECE-BY-PIECE PICK UP EACH PIECE AND APPLY THE #BC-32 NITRILE RUBBER ADHESIVE ON TO THE BOTTOM OF EACH GASKET PIECE AND LIGHTLY PLACE IT BACK ON TO THE FRAME WHERE YOU REMOVED IT FROM. WHEN ALL THE PIECES HAVE BEEN COATED WITH THE ADHESIVE AND ALIGNED BACK ON THE FRAME, FIRMLY PRESS THEM INTO PLACE. THIS WILL TAKE ABOUT 30 MINUTES TO FIXTURE CURE. IF YOU WOULD LIKE TO SPEED UP THIS PROCESS YOU CAN TACK THE GASKETS SECTIONS AFTER YOU COMPLETED THE ABOVE PROCESS BY APPLYING A BEAD OF EITHER THE CLEAR #GA-422 OR THE BLACK #GA-410 AROUND THE INSIDE OF THE PROPERLY POSITIONED GASKET AS A FILET AND SPRAY WITH THE LIGHTNING TACK TO IMMEDIATELY KEEP THE GASKET FROM SHIFTING. YOU DON’T HAVE APPLY A COMPLETE BEAD, A SMALL BEAD ON AT LEAST TWO SPOTS ON EACH PIECE SHOULD DO THE JOB.
