1.50" Brass Floor Cones / Speaker Spikes

Brass Speaker Spike 1.50" floor cone best price

These spikes are perfect for larger speakers or sub woofers.

They are machined from brass and have a Black Chrome base and a Gold Nickel tip.

They are 1.50" tall not including threaded rod and are 1.25" wide.

The threads are available in 1/4-20 (standard) and custom threads of  M6 (6mm), 5/16, M8 (8mm), 3/8, and 1/2". Please see the Speaker Thread Sizes by Manufacturer page to find the thread size for your speakers.

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 very heavy duty spikes and great for larger loudspeakers or subwoofers.

The spikes do not come with the match floor cups but they can be added to your order by following this link. Brass Floor Cups.

** Spike Tip ** - Mount (2) of the 1.50" spikes on the rear and (2) of the 2.10" spikes to the front of your speaker to obtain the correct "tilt" for correct imaging.
