Heavy duty speaker spikes made of steel

These cones are our newest and largest all steel cones in our lineup.

They are machined from 1018 CRS and are available with a black BK-05 smooth powder coat. finish

They are 2.00" tall not including threaded rod and are 1.50" wide.

The threads are available in 1/4-20 (standard).

If your speaker does not have an insert already installed, no problem. Each standard 1/4-20 spike comes with a 1/4-20 stud and threaded insert. The threaded insert can easily be screwed into a 9 mm pre-drilled hole with an M6 or 7/32 Allen wrench. No need for this insert if your speakers already have inserts installed. Be sure to order the 1/4-20 (standard) to include the 1/4-20 stud and insert.

These are super robust and great for larger loudspeakers or audio racks.

We have used these cones in applications exceeding 1200 lbs with (4) cones!
