         Speaker Spikes FAQ

Installation is pretty simple:
Drill a 9mm hole (nearest decimal equivalent is fine .354") thru and then turn the insert into place using a 6mm allen wrench. I recommend using a smaller pilot drill before the 9mm so the 9mm drill doesn't walk around. Any hardware store would carry the allen wrench if you don't have one. They cost a buck or so.

I recommend centering your hole an inch from each edge. This would let the spike be seen but doesn't stick out the sides. I always say measure twice and cut once. Try the drilling and installing on a scrap piece of wood to eliminate any chance of messing up and getting your process down :) You can always back out the insert using the 6mm allen wrench.

If you don't have a 9 mm drill bit you can use a 3/8" (.375") instead.

It looks like some of your spikes (1.50" and 2.00") have a tip. What are these used for?

Our 1.50" and 2.00" spikes come in (2) pieces for (2) different reasons. Both of these spikes actually use the same base cone. The base of the spike can have .1375" or .626" tips screwed into them. This gives some flexibility to the end height and look of the spike. It also allows for some adjustment if you are setting your speaker on an unleveled surface.

Can I use spikes on my components?

The 1.50" and 2.00" both can be used under components by simply removing the thread from the base and placing under components. It is advised that the base of the cone by secured by using double sided tape which we will supply upon request.

Of course, we do have a few different component points that are specifically made for this purpose that would work even better.

To what depth should the spikes pierce the carpet?

Is is very important that the spikes tips pierce all the way through the carpet, pad, and touch the sub floor. Send them home!

My speakers are not on your manufacturers thread size list, how can I tell what thread size I need?

We usually ask that you find a local hardware store to find a couple different sized bolts that look about the right size. If the thread size is about the diameter of a standard pencil then it's probably 1/4-20 or M6 (6mm), if is bigger then perhaps 3/8-16 or M8 (8mm). It's always a good idea to double check if you're in doubt as speaker manufactures change inserts time to time depending on availability and weird engineers moods. They're moody you know...really.

 

** Spike Tip ** - Mount (2) of the 1.50" spikes on the rear and (2) of the 2.15" spikes to the front of your speaker to obtain the correct "tilt" for correct imaging.
