TeleLock Speaker Pole

The Ultimate Support SP90B is a lightweight aluminium speaker pole designed for live sound and installed audio applications. Its TeleLock lift assist helps operators raise and lower satellite speakers smoothly. The pole accepts both standard 1.375in and M20 subwoofer mounts for broad compatibility.

Height Range and Load Limit

The pole extends from 36.5in to 57.2in using oversized 1.5in and 1.75in tubing. A weight rating of 150lbs sets the maximum load for the attached speaker. Exceeding this limit or extending beyond the stated range compromises stability and safety.

Capacity and Headroom

At 3.85lbs the pole is light enough for one-person setup yet rigid enough for typical satellite speakers. It comfortably handles cabinets within the 150lb rating at any height within the 36.5in to 57.2in window. Heavier arrays or taller coverage needs exceed the design envelope.

Questions about this item

Which version of the SP90B pole should I choose for a standard 1.375-inch speaker mount versus a thread-on M20 mount?

The SP-90 works with both a standard 1.375in mount and a thread-on M20 mount, so one pole covers either subwoofer adapter type.

What does the 150 lb weight rating mean when the pole is extended to 57.2 inches?

The 150 lb (68.2 kg) rating applies across the full 36.5–57.2 in height range, so a 150 lb speaker is supported even at maximum extension.

How does the TeleLock® lift assist interact with the 1.5-inch upper tube and 1.75-inch lower tube?

TeleLock® securely grips the telescoping 1.5 in upper tube inside the 1.75 in lower tube, letting you set height smoothly and lock it without a separate pin.
