Professional metal corners designed for PA speaker and subwoofer cabinet repair and reinforcement. These 1.5" x 1.5" x 1.5" silver corners mount specifically to the back of speaker cabinets where standard front corners don't fit properly.

Each corner provides structural reinforcement at vulnerable cabinet joints while maintaining the professional appearance of your PA system. The metal construction handles the rigors of transport and setup better than plastic alternatives that crack under stress.

At 1.5 inches on each side, these corners fit most standard PA speaker and subwoofer cabinets without interfering with ports, handles, or other hardware. The silver finish matches common speaker hardware and won't show scuff marks like black corners. Eight corners per pack gives you enough for two full cabinets or spares for your repair kit.

Essential for mobile DJs who transport speakers weekly, bands on tour, and sound companies maintaining rental inventory. Also useful for churches and venues doing cabinet refurbishment or replacing damaged corners on house PA systems.

Each corner mounts with standard wood screws (not included) and fits flush against cabinet surfaces. The pack includes eight identical back-mount corners - no additional hardware or cables needed.

Seismic Audio backs these corners with a one-year warranty and ships them ready to install. Keep spares on hand for road repairs and cabinet maintenance projects.

Frequently Asked Questions

What's the difference between back corners and regular speaker corners?

Back corners have a different mounting profile designed specifically for the rear of speaker cabinets where standard front corners don't fit properly. The geometry accommodates the typical cabinet construction and hardware placement found on the back of PA speakers and subwoofers.

How many corners do I need for a complete speaker cabinet?

Most PA speakers and subwoofers use 4-8 corners total depending on size and design. This 8-pack provides enough corners for two smaller cabinets or one large subwoofer, with some spares for future repairs or other cabinets in your system.

What size screws do these corners require?

These corners mount with standard wood screws, typically #8 or #10 screws depending on your cabinet material thickness. The mounting holes accommodate common screw sizes used in speaker cabinet construction. Screws are not included with the corners.

Can I use these corners on homemade or custom speaker cabinets?

Yes, these corners work with any wood cabinet construction where you need back-mount corner reinforcement. They're commonly used by DIY speaker builders and cabinet shops for both new construction and repair work on PA speakers and subwoofers.

Do these corners fit both PA speakers and subwoofers?

These corners work on both PA speakers and subwoofer cabinets. The 1.5" dimensions and back-mount design accommodate most standard cabinet construction methods used for both full-range speakers and dedicated low-frequency enclosures.
