2 Kingstons, 4 Berlins
Spray Silicon, Lithium Grease Brush (bag), 2 Step Ladders, 2 or 3 people, Stacking Instructions, 1” hard Foam Mat, 8 Stacking Bolts (5/16” x 2 ½”) and washers (16), Drill, Bolt Driver, Hand Broom, Level, Rubber Mallet, Hammer, Prybar, Lg. Screwdriver, Armorall, Rags, Speaker Stand, 1 Quad Coupler, 3 Dual Couplers, 2 6” Stacking Posts, 2 12/3 Wire Shims, 2 Pipe Clamps
Place 2 Kingstons side by side. Remove the 8 Kingston 5/16” x ½” Cap bolts from stacking stand holes. Place 1” hard foam pad on top of the side by side Kingstons. Place 2 large speakers face down on the 1” hard foam pad.
Prepare the Stacking Stand. There are 4 lubricated stacking posts inserted into the 4 post holes of the speaker stand. They are stored with the posts flush with the speaker/stand interface side of the stand. Knock the 2 outside stand posts 2” through the stand post holes so they stick out from the speaker stand, on the speaker side, by 2”. Place the speaker stand over the bottom of the face down speakers and locate the protruding stand posts over the outside post holes on the back of the face down speakers, and pound in partially with a rubber mallet. Then pound in partially the two inside stand posts into the opposing speaker post holes. Finish driving the 4 posts all the way in. Finish mating the speaker stand and speakers by clamping with the 2 pipe clamps, while the speakers are still face down. Tap each post with the mallet making sure they are all the way in.
Remove the pipe clamps, pull the face down speakers and speaker stand on the 1” foam pad forward, toward the front of the Kingstons and rotate up the the vertical position on top of the Kingstons. Line up the bolt holes in the stand with the bolt pattern on top of the Kingstons and bolt the stand to the Kingstons with the 8 provided 5/16” x 2 ½” bolts and 16 washers.
Place 6” stacking posts (without the rubber caps) in the post holes on top of the speakers attached to the speaker stand, and thread the (12/3) round rubber jacketed shim wire through the 2 speaker handles on top of the stacked speakers.
Stack the next level of speakers, joining the bottom posthole with the stack posts protruding from the top of the first row of speakers. Join 1 quad and 3 dual couplers to the back of the 4 stacked speakers.
If the stack is on the floor, and not on the top of the Kingstons, then a third row of 30-15 speakers can be stacked in a like fashion. In this case, 2 quad and 5 dual couplers will.
